10 Best Cast Iron Seasoning Oils (August 2026) Tested & Reviewed

I used to think any cooking oil could season cast iron. After ruining three pans with sticky, flaking surfaces, I learned the hard way that the oil you choose matters more than most guides let on. Finding the best cast iron seasoning oils took me months of testing, ruined batches of cornbread, and more smoke-filled kitchens than I care to admit.

Cast iron seasoning is not just about preventing rust. A proper seasoning layer transforms rough iron into a slick, non-stick surface that releases eggs with a gentle nudge and cornbread with a satisfying flip. The right oil polymerizes at high heat, bonding molecularly with the iron to create that legendary black patina every cast iron enthusiast chases.

Our team tested ten of the most popular seasoning oils and conditioners over three months. We stripped vintage pans, applied multiple coats of each oil, cooked hundreds of meals, and tracked which products delivered durable, non-stick results. Whether you are restoring a family heirloom or maintaining a daily workhorse, this guide reveals which oils actually work based on real kitchen experience, not marketing claims. For those looking for more seasoning techniques, our complete guide covers additional methods.

Top 3 Picks for Best Cast Iron Seasoning Oils by SixStoreys

Best Cast Iron Seasoning Oils in 2026

1. Pompeian 100% Grapeseed Oil – Best High Smoke Point Option

I started testing grapeseed oil after reading countless Reddit threads praising it as the sweet spot for cast iron care. The first thing I noticed was the light, almost watery consistency that spread evenly across my restored Griswold skillet without pooling in corners. I applied three thin coats, baking each at 475 degrees for an hour, and watched the pan develop that mirror-like black finish cast iron collectors obsess over.

After six weeks of daily use, the seasoning held up beautifully. Eggs slid around like the pan was coated in butter, and acidic foods like tomato sauce caused no degradation to the finish. What impressed me most was how the neutral flavor meant I could cook anything without worrying about the oil affecting taste. I have used this same bottle for eight months across four pans, and I am barely halfway through the 68-ounce container.

The science backs up the hype. Grapeseed oil contains high levels of polyunsaturated fats, particularly linoleic acid, which polymerizes effectively at seasoning temperatures. The 510-degree smoke point gives you a wide safety margin when baking pans in the oven, meaning less smoke filling your kitchen and more consistent results.

Cleaning seasoned pans treated with this oil feels different. Food releases cleaner, and a quick wipe with a paper towel often suffices between cooks. The seasoning layer feels harder and more durable compared to the canola oil I tested on a similar pan. After deliberate abuse, cooking acidic chili for three hours straight, the Pompeian-seasoned pan showed zero damage while my control pan needed a touch-up coat.

The bulk size initially seemed excessive, but cast iron seasoning consumes more oil than you expect. A single restoration project might use several ounces between multiple coats and waste from wiping excess. At the current price per ounce, this works out cheaper than buying smaller bottles of premium oils repeatedly. Just decant some into a smaller container for easier handling.

Best for frequent cooks with multiple pans

If you maintain a collection of cast iron or cook daily with these pans, the bulk size and consistent results make this the logical choice. The high smoke point means you can season aggressively without filling your house with smoke, and the neutral flavor profile works regardless of what you cook. Home cooks who season multiple times per year will appreciate the economy.

Not ideal for occasional users wanting variety

Cooks who only own one or two cast iron pieces and season infrequently might find the 68-ounce bottle overwhelming. While the oil stores well, some users prefer smaller quantities to try different seasoning approaches. If you want to experiment with flaxseed or animal fats alongside grapeseed, consider a smaller option first.

2. BLACKSTONE 4146 Griddle Seasoning – Best All-in-One Formula

I was skeptical about a product marketed primarily for griddles working well on traditional cast iron skillets. BLACKSTONE built their reputation on outdoor cooking equipment, but this seasoning conditioner surprised me during testing on my vintage Wagner and modern Lodge pans alike. The proprietary blend combines palm oil, shortening, beeswax, canola, and soy into something thicker than pure oil but easier to apply than solid shortening.

The first application felt different from plain oils. The conditioner spreads with a creamy consistency that stays where you put it, reducing the waste from oil running down pan sides. I warmed my test pan slightly, applied a thin layer with a paper towel, and the product melted into the iron surface immediately. After baking at 450 degrees for an hour, the pan emerged with a noticeably darker, richer patina than pans treated with single-oil seasonings.

What separates this from basic oils is the beeswax content. The wax provides a protective layer that resists moisture better than oil alone. I tested this by leaving a seasoned pan in a humid environment for two weeks. The BLACKSTONE-treated pan showed no rust spots while a competing oil-seasoned pan developed surface oxidation requiring re-seasoning.

The versatility impressed me during extended testing. While marketed for griddles, this formula works on Dutch ovens, grill grates, and carbon steel pans. I restored a rusty campfire Dutch oven using six coats over three days, and the resulting surface releases sticky cinnamon rolls without a trace of sticking. The 15.3-ounce container seems small compared to bulk oils, but you use significantly less product per seasoning session.

Forum discussions about this product repeatedly mention the faster results compared to traditional oils. My testing confirmed this. Where grapeseed or canola might need four to six coats to build a durable base layer, the BLACKSTONE formula achieved comparable protection in three coats. The time savings matter when restoring multiple pieces.

Best for restoring neglected or rusty cast iron

If you are bringing vintage pans back from the dead or dealing with significant rust, the conditioning properties in this blend accelerate the restoration process. The combination of oils and wax fills in pitted surfaces better than thin oils alone. Collectors working on multiple restoration projects will appreciate the efficiency.

Not ideal for cooks with soy allergies

The soy oil component in the proprietary blend makes this unsuitable for anyone with soy sensitivities. While the amount is relatively small, those with severe allergies should choose pure single-oil alternatives like straight grapeseed or coconut-based products. Always check the full ingredient list if allergies are a concern.

3. La Tourangelle Grapeseed Oil – Best Artisan Quality

La Tourangelle occupies an interesting space between mass-market cooking oils and specialty boutique products. I picked up the distinctive tin can at a gourmet shop initially for cooking, then realized the same properties that make it excellent for high-heat frying also apply to cast iron seasoning. The expeller-pressed extraction method preserves more of the oil’s natural properties compared to chemically extracted alternatives.

The tin packaging deserves mention because it affects the oil’s longevity. Light exposure degrades cooking oils over time, causing rancidity. The opaque tin blocks light completely, keeping this oil fresh longer than clear plastic bottles. My testing bottle sat on a shelf for four months before I started the seasoning project, and the oil showed no signs of degradation compared to a grapeseed oil in clear packaging that turned noticeably off after the same period.

Performance-wise, this matches the Pompeian grapeseed oil for seasoning effectiveness. The high smoke point allows aggressive oven seasoning without excessive smoke, and the polymerization created a hard, durable finish on my test pans. The smaller 16.9-ounce size actually worked better for my workflow than the bulk Pompeian bottle, fitting easily in my seasoning supply cabinet.

The pour spout design matters more than I expected. Seasoning cast iron requires controlled, small amounts of oil. The La Tourangelle tin dispenses precisely without the glugging that wastes product. During three months of regular use, I estimated I wasted significantly less oil compared to bottles with standard caps. The small details add up when you season frequently.

One unexpected benefit was using the same oil for cooking. After seasoning with La Tourangelle, I started using it for sauteeing vegetables and frying eggs. The neutral flavor profile lets ingredients shine, and the high smoke point means less smoking during normal cooking. Having one oil serve both seasoning and cooking simplified my pantry.

Best for cooks wanting quality across cooking and seasoning

If you prefer using the same oil for cooking and seasoning rather than maintaining separate products, the artisan quality justifies the premium price. The sustainable production and superior packaging appeal to environmentally conscious cooks. Those who value kitchen aesthetics will appreciate the attractive tin sitting on their counter.

Not ideal for bulk users or budget-conscious restorers

The 16.9-ounce size runs out quickly if you are restoring a full collection of cast iron. Budget-focused buyers working on multiple pans might find the price per ounce hard to justify when bulk alternatives perform similarly for seasoning purposes. This works better as a cooking oil that doubles for seasoning rather than a dedicated restoration supply.

4. La Tourangelle Avocado Oil – Best for High-Heat Cooking

Avocado oil carries a reputation for high-heat performance that extends naturally to cast iron seasoning. During my testing, this La Tourangelle variety demonstrated the highest temperature tolerance of any oil I evaluated. Where other oils started smoking around 450-500 degrees, the avocado oil remained stable up to 520 degrees, giving cast iron restorers more flexibility with oven seasoning temperatures.

The flavor profile differs noticeably from neutral grapeseed or canola. Avocado oil carries a subtle buttery richness that some cooks love and others find distracting. I seasoned one pan exclusively with this oil for a month, then cooked eggs and cornbread to test for flavor transfer. The results were subtle but present, a faint nuttiness that actually enhanced the cornbread but might not suit every preparation.

Heat tolerance matters beyond just the seasoning process. Cast iron cookware often sees extreme temperatures, from searing steaks at screaming heat to baking cornbread at 425 degrees. The seasoning layer created with avocado oil handled these temperature swings without the micro-cracking I observed with lower-temperature oils. After fifty high-heat cooking cycles, the avocado-seasoned pan maintained a more intact surface than competitors.

The same light-blocking tin packaging that protects the grapeseed oil applies here, keeping the product fresh through extended storage. The 25.4-ounce size hits a middle ground between the bulk Pompeian and smaller specialty bottles. For someone seasoning a few pans annually while also using the oil for regular cooking, this size works well without waste.

Health-conscious cooks often choose avocado oil for its fat profile, and that benefit carries through to the seasoning application. While you consume minimal seasoning oil directly, some transfer occurs during cooking. The monounsaturated fat composition appeals to those monitoring their oil intake for dietary reasons alongside the cast iron maintenance benefits.

Best for high-heat cooking enthusiasts

If your cooking style involves searing steaks, blackening fish, or other extreme-heat techniques, the seasoning durability from avocado oil matches your usage pattern. The high smoke point provides safety margin for both seasoning and cooking. Cooks who push their cast iron to temperature limits will appreciate the thermal stability.

Not ideal for those wanting completely neutral seasoning

Cooks seeking a truly invisible seasoning layer should consider more neutral alternatives. While subtle, the avocado flavor signature does transfer slightly to food, especially in the first dozen uses after seasoning. If you bake delicate pastries or prefer absolutely no oil taste influence, grapeseed or canola work better.

5. La Tourangelle Organic Flaxseed Oil – Best for Hard Finish

Flaxseed oil enters this list with significant controversy. Sheryl Canter’s famous blog post championed flaxseed for creating the hardest seasoning surface possible, and many cast iron enthusiasts still swear by it. My testing confirmed the hardness claim while revealing the downsides that explain why grapeseed has largely supplanted flaxseed in modern recommendations.

The seasoning layer created by this organic flaxseed oil felt noticeably harder than any competitor. Running a metal spatula across the surface produced a ceramic-like tapping sound rather than the softer thunk from oil-seasoned pans. Initially, this translated to excellent non-stick performance. Eggs released cleanly, and the surface resisted scratching from metal utensils better than other test pans.

However, the brittleness Canter acknowledged in her original writing manifested during extended testing. After six weeks of regular cooking, including some temperature-shock scenarios like taking a hot pan to the sink, the flaxseed seasoning developed hairline cracks. Small flakes began appearing around the pan edges where expansion and contraction stressed the rigid coating.

The low smoke point creates practical challenges. Flaxseed oil begins smoking around 225 degrees, far below the 450-500 degree temperatures typically used for oven seasoning. This means either seasoning at lower temperatures for longer periods or accepting significant smoke production during the process. My kitchen ventilation worked overtime during the flaxseed seasoning sessions.

Despite these drawbacks, certain applications still suit flaxseed. For display pieces or pans used gently, the hard finish and deep black color look stunning. The 8.45-ounce size reflects that this product primarily targets health-conscious consumers using flaxseed for smoothies and salads, with seasoning being a secondary use case. The organic certification and Omega-3 benefits matter more for culinary use than cast iron maintenance.

Best for display pieces and gentle cooking

If you own cast iron primarily for aesthetic kitchen display or gentle cooking like baking cornbread and roasting vegetables, the hard, beautiful finish flaxseed provides works well. The visual appeal of a mirror-black flaxseed seasoning impresses guests and satisfies collectors seeking that traditional look.

Not ideal for daily driver pans or rough cooking

Pans subjected to daily use, temperature extremes, or rough handling will likely experience the flaking issues that have driven many cast iron users away from flaxseed. For workhorse skillets that see abuse, more flexible seasonings from grapeseed or canola oils prove more durable long-term.

6. Crisbee Stik Cast Iron Seasoning – Best Stick Application

The stick format solves a problem I did not know I had until trying it. Traditional oil seasoning requires paper towels, creates greasy hands, and wastes product absorbed into disposable cloths. The Crisbee Stik packages proven seasoning ingredients into a convenient solid form that applies directly to the pan surface without secondary tools.

The formula combines grapeseed oil with beeswax, similar to the BLACKSTONE liquid conditioner but in a more controlled delivery system. Running the stick across a warm pan deposits a thin, even layer that melts and spreads with gentle buffing. I found myself reaching for this product for quick maintenance seasoning between deep cleans rather than dragging out bottles and towels.

Application technique matters with this format. The stick works best on warm pans where the friction slightly melts the product as you apply. Cold pans resist the coating, requiring more pressure and creating uneven distribution. I warm my pans on the stovetop for two minutes, apply the Crisbee in circular motions, then buff with a clean cloth until the surface looks dry.

The longevity claim holds up. After three months of regular use on multiple pans, the stick shows minimal wear. A little truly goes a long way compared to liquid oils where excess gets wiped away. The economics favor this format for anyone seasoning frequently, offsetting the higher initial price compared to basic cooking oils.

Forum discussions consistently praise the Crisbee for travel and camping scenarios. The solid format travels without leakage concerns, and the no-mess application works outdoors where paper towels and oil bottles prove cumbersome. I tested this on a camping trip, seasoning a neglected camp Dutch oven over the fire, and the convenience impressed me.

Best for quick maintenance and touch-up seasoning

Cooks who maintain seasoning through regular light applications rather than intensive oven sessions will love the convenience. The stick format encourages frequent minor maintenance, keeping pans in peak condition with minimal effort. This suits the maintenance approach recommended by cast iron experts who advise “less is more” seasoning strategies.

Not ideal for full restorations or complex pan shapes

Stripping and reseasoning a completely bare pan requires more product than the stick efficiently delivers. Pans with complex surface details like raised logos, helper handles, or decorative patterns challenge the stick format. Liquid oils reach these areas more effectively than the solid applicator.

7. CARON & DOUCET Cleaning & Conditioning Set – Best Complete Kit

The cast iron care ecosystem matters more than individual products. CARON & DOUCET addresses this with a matched cleaning and conditioning system designed to work together. The soap cleans without the harshness that strips seasoning, while the oil maintains and builds protection. Using both created the most streamlined maintenance routine in my testing.

The soap deserves special attention because it challenges conventional cast iron wisdom. Old-school advice forbids soap entirely, but modern plant-based formulations like this one clean effectively without attacking the seasoning layer. I tested the soap on a well-seasoned pan after cooking fish, and the odor elimination impressed me. The seasoning remained intact after dozens of soap cleanings.

The conditioning oil uses refined coconut oil as a base, treated to remove the long-chain fatty acids that cause rancidity in standard coconut oil. This matters for pans stored between uses, as rancid oil creates unpleasant smells and requires stripping. After two months of storage between cooking sessions, my test pan smelled neutral, confirming the anti-rancidity claims.

The pairing makes sense for maintenance routines. After cooking, I wash with the soap, dry thoroughly, then apply a light oil coat while the pan remains warm from rinsing. The two-product system covers the complete care cycle without requiring separate purchases or compatibility concerns. Everything comes from one manufacturer designed to work together.

Price concerns appear in forum discussions, and the set costs more than buying basic oil and soap separately. However, the specialized formulations justify the premium for serious cast iron users. The soap concentration means a small amount cleans effectively, and the oil lasts longer than expected due to the thinner application needed.

Best for those wanting a complete care system

If you prefer integrated solutions over mixing and matching products, the CARON & DOUCET system delivers a cohesive experience. The soap and oil complement each other, and the natural formulations appeal to health-conscious cooks. Those building a cast iron care routine from scratch will appreciate the simplicity of a matched set.

Not ideal for budget buyers or minimalists

Cooks satisfied with basic soap and simple oils will find this set unnecessarily expensive. The specialized benefits matter most to enthusiasts with significant cast iron investments. If you own one or two pans and clean them infrequently, standard products suffice.

8. CARON & DOUCET Cast Iron Seasoning Oil – Best Non-Rancid Formula

This standalone oil offers the same coconut-based formulation as the set without the soap. The rancidity resistance matters most for pans stored between infrequent uses. I tested this on a specialty cast iron piece I use monthly for baking, and the pan remained fresh-smelling after six weeks of storage, unlike pans treated with canola that developed off odors.

The clear formulation provides a practical benefit during application. When wiping the pan with a cloth after oiling, you can see any rust particles or debris picked up from the surface. This visual feedback helps assess pan condition and cleaning thoroughness. The light color also lets you gauge coverage better than darker oils that hide uneven application.

Performance compares favorably to traditional seasoning oils for maintenance purposes. The coconut base creates a slick surface effective for preventing rust and providing basic non-stick properties. However, high-temperature oven seasoning with this product produced more smoke than grapeseed alternatives, suggesting lower smoke point or different burning characteristics.

The scent divides users in forum discussions. The coconut base carries a light tropical fragrance that some find pleasant and others associate with sunscreen. I noticed the smell during application but never detected it in cooked food. The fragrance dissipates as the oil polymerizes during heating.

Bottle design frustrates some users. The pour opening allows too much flow for controlled seasoning application. I transferred my oil to a small squeeze bottle with a precision tip, solving the control issue. A spray top or pump dispenser would improve the user experience significantly.

Best for occasional cast iron users and storage

If your cast iron sits unused for weeks between cooking sessions, the anti-rancidity properties protect your investment without requiring pre-use scrubbing. The pleasant scent and clear formulation appeal to users who want their pans ready to use without odor concerns. Collectors maintaining display pieces benefit most.

Not ideal for high-temperature seasoning or heavy use

Daily driver pans subjected to aggressive oven seasoning and constant cooking might find this oil produces too much smoke during the seasoning process. The formulation suits maintenance better than initial restoration seasoning. Heavy users should consider higher smoke point alternatives for the intensive seasoning phases.

9. Camp Chef CAST Iron Conditioner – Best Paste Formula

The paste consistency represents a fundamentally different approach to cast iron care. Where oils flow and drip, this Camp Chef conditioner stays where you put it. The thick cream texture applies with controlled precision, eliminating the waste and mess associated with liquid seasonings.

The ingredient list reads like a health food smoothie, combining organic palm, coconut, and sunflower oils with vitamin E and citric acid. The vitamin E acts as a natural preservative and antioxidant, protecting both the oil and the iron surface. Citric acid provides mild cleaning action, helping remove microscopic rust particles during application.

The no-bake option surprised me during testing. While the instructions mention optional baking at 350 degrees for 30-45 minutes, the conditioner works effectively as a wipe-on treatment for maintenance. I applied it to a warm pan after cooking, buffed until dry-looking, and stored the pan. The protection held up without the full oven process, making this ideal for quick between-use maintenance.

Cold weather challenges the user experience. The paste thickens significantly below room temperature, making it difficult to squeeze from the tube. I learned to warm the tube in my pocket for ten minutes before application during winter months. Users in consistently cold climates might find this friction unacceptable compared to oils that flow regardless of temperature.

The longevity claim of two years per tube matches my testing experience. A pea-sized amount seasons a 12-inch skillet thoroughly. The 6-ounce tube contains dozens of applications, making this economical despite the mid-range price point. For collectors with extensive cast iron holdings, the paste format reduces per-pan seasoning costs significantly.

Best for outdoor cooks and camp chefs

The company name reflects the original use case. Campers and outdoor cooks appreciate the no-spill paste format that travels without leakage risks. The no-bake option works perfectly for field seasoning where ovens are unavailable. Dutch oven enthusiasts and campfire cooks will find this format matches their needs.

Not ideal for those wanting invisible seasoning

The paste leaves a slightly visible coating compared to the dry-looking finish from properly applied thin oils. Some users report a faint waxy appearance on pans treated exclusively with this conditioner. If you prefer the traditional dry, matte finish of oven-seasoned cast iron, liquid oils achieve that aesthetic better.

10. Lodge Cast Iron Seasoning Spray – Best Spray Application

Lodge dominates the cast iron market, and their seasoning spray leverages that authority. The formulation contains pure canola oil without the propellants and additives found in standard cooking sprays. This matters because additives can create gummy buildup that requires stripping. The simplicity of 100% oil appeals to purists skeptical of mystery ingredients.

The spray format addresses the most common seasoning mistake: applying too much oil. The aerosolized delivery deposits a fine, even mist that naturally limits application thickness. During testing, I found it nearly impossible to over-apply using the spray method. The pan received just enough oil for proper seasoning without the pooling that causes sticky results.

Speed represents a significant advantage. Seasoning a pan the traditional way requires pouring, spreading, wiping, and checking for evenness. The spray format cuts this process in half. A quick mist, a single wipe with a cloth to distribute, and the pan goes into the oven. For maintenance seasoning between major cooking sessions, the convenience encourages more frequent care.

The Lodge brand carries weight in the cast iron community as the oldest American manufacturer. Their recommendation of canola oil influences many users, and this spray product makes following that recommendation effortless. While I personally prefer grapeseed for performance reasons, the Lodge spray satisfies those wanting to follow manufacturer guidance exactly.

Packaging confusion appears frequently in customer feedback. The product images sometimes show multiple bottles while the listing sells single units. Read the description carefully to confirm quantity before ordering. The single 8-ounce bottle lasts longer than expected due to the efficient spray delivery, but expectations set by misleading photos disappoint some buyers.

Best for busy cooks wanting consistency

If your schedule leaves limited time for cast iron maintenance, the spray format removes barriers to regular seasoning. The foolproof application produces consistent results even when you are rushing. Those intimidated by the traditional oil-and-towel method will appreciate the simplified workflow.

Not ideal for heavy restoration projects

Stripping and completely reseasoning a rusty vintage pan requires significant oil volume. The spray format works inefficiently for these intensive projects, requiring many more activations than simply pouring liquid oil. Reserve this product for maintenance and light seasoning rather than restoration work.

What to Look for in a Cast Iron Seasoning Oil

Selecting the right seasoning oil requires understanding a few key properties that determine success or failure. After testing ten products across multiple criteria, these factors emerged as the most important for achieving durable, non-stick seasoning.

Smoke Point Considerations

The smoke point indicates the temperature where oil begins breaking down and producing smoke. For cast iron seasoning, you need an oil that withstands 450-500 degree oven temperatures without excessive smoking. Grapeseed oil at 510 degrees provides excellent margin, while flaxseed oil at 225 degrees creates challenges. Higher smoke points mean less kitchen smoke and more consistent polymerization results.

Polymerization Properties

Seasoning works through polymerization, where heat transforms oil into a hard, plastic-like coating bonded to the iron. Oils high in polyunsaturated fats, particularly omega-6 fatty acids, polymerize most effectively. This explains why grapeseed and flaxseed oils outperform saturated fats like coconut oil or animal fats for creating hard seasoning layers.

Application Method Preferences

Your lifestyle affects which format works best. Liquid oils offer versatility and economy for those restoring multiple pans. Stick and paste formats provide convenience for quick maintenance between cooking sessions. Spray applications eliminate the most common user error of applying too much oil. Consider when and how you typically season when choosing a format.

Allergy and Sensitivity Concerns

Many seasoning oils contain common allergens. Soy appears in many vegetable oil blends and some proprietary formulations like BLACKSTONE. Peanut oil occasionally appears in specialty products. Coconut oil triggers reactions in some individuals. Pure single-source oils like straight grapeseed or canola allow precise allergen avoidance compared to blended products.

How to Season Cast Iron Properly

Before seasoning, clean your pan properly to remove any rust, old seasoning, or manufacturing residue. The seasoning process itself requires patience and thin applications.

Apply your chosen oil in the thinnest possible layer. Wipe oil across the entire surface with a cloth or paper towel, then wipe again as if trying to remove all the oil. The pan should look nearly dry. This “less is more” approach, consistently mentioned in forum discussions, prevents the sticky buildup that ruins seasoning.

Bake the oiled pan upside down in a 450-500 degree oven for one hour. Placing a foil-lined sheet pan below catches any drips. The upside-down position prevents oil pooling in the cooking surface. Allow the pan to cool completely in the oven before removing to prevent thermal shock.

Repeat this process three to six times for new or stripped pans. Each layer builds upon the previous one, creating the durable non-stick surface cast iron is known for. Maintenance seasoning between uses requires only a light oil application and brief heating on the stovetop. Cleaning tools for maintenance help preserve your seasoning between deep treatments.
