Top 3 Picks for Best Parts Washers

These three models stood out across all our testing categories. They represent the best balance of cleaning performance, build quality, and overall value for different budgets and use cases.

The Eastwood 40-gallon earned our Editor’s Choice because it handles the widest range of parts with its deep 10-inch tub and powerful 5.3 GPM pump. The Eastwood 20-gallon takes Best Value since it delivers nearly the same build quality at roughly half the price. For those just starting out, the JEGS 5-gallon portable is a proven Budget Pick with one of the highest ratings on our list.

Best Parts Washers in 2026

Here is a quick overview of all 10 models we reviewed. Use this table to compare key specs at a glance, then read the individual reviews below for the full breakdown.

1. JEGS 5-Gallon Portable Parts Washer – Best Budget Benchtop

I picked up the JEGS 5-gallon portable parts washer for a small engine rebuild project, and it immediately proved its worth as the best budget benchtop option on the market. At just 16.75 pounds and measuring 14.25 by 17.38 by 8.75 inches, this unit fits on any workbench without eating up valuable shop space. The 3.5-gallon solvent capacity is enough for cleaning carburetors, wheel bearings, and small engine components.

The 3.96 GPM pump delivers surprisingly strong flow for a benchtop unit. I used it with Simple Green Industrial water-based degreaser, and it cut through caked-on grease on a Briggs and Stratton carburetor in about 10 minutes. The removable tray is a nice touch because you can pull the whole parts basket out, dump the debris, and reload without making a mess.

One thing I noticed right away is that JEGS priced this washer at roughly one-third the cost of the comparable Eastwood benchtop unit. That value proposition is hard to beat for a hobbyist or small shop. The powder-coated black steel finish with the JEGS logo looks clean and has held up well after three months of weekly use. I also appreciate that it works well with water-based degreasers, which are safer and more environmentally friendly than petroleum solvents.

The downsides are real but manageable. There is no gasket under the lid, so solvent evaporates during storage if you do not add a weatherstrip seal yourself. The pump produces more flow than the small tank can comfortably handle, which causes splashing if you run it at full blast. A flow-thru brush attachment sold separately helps control the spray and makes the unit much more functional.

Solvent Compatibility and Maintenance

The JEGS 5-gallon is rated for petroleum-based solvent but does not include a fusible link for flammable solvent safety. I recommend sticking with water-based degreasers like Simple Green to avoid any fire risk. There is no built-in filter on the pump intake, just a basic grating, so you will want to periodically clean debris from the bottom of the tank to prevent clogs.

Who Should Buy This

This washer is perfect for bicycle mechanics, DIY engine rebuilders, hobbyists, and small-shop technicians who clean small to medium parts occasionally. If you are just getting into automotive work and want a capable parts washer without spending $200 or more, the JEGS 5-gallon is the best starting point on our list of best parts washers.

2. Jack Boss 3.5 Gallon Parts Washer – Compact with Safety Lid

The Jack Boss 3.5-gallon parts washer caught my attention because it is one of the few budget models that includes a fusible link lid for fire safety. That hinged lid automatically snaps shut if temperatures rise unexpectedly, which gives you peace of mind that the JEGS 5-gallon does not offer at this price point. The work basin measures 18 inches wide by 13.5 inches deep by 9 inches high, giving you slightly more working room than the JEGS.

I tested it cleaning wheel bearings, gears, and a carburetor from a motorcycle restoration project. The 110V electric pump does the job, but the 0.5 GPM flow rate is noticeably slower than the JEGS or redsun models. Parts take longer to clean, and you need more patience and manual brushing to get the same results. For light DIY work this is fine, but if you are cleaning parts daily, the slow flow will frustrate you.

The build quality is solid for the price. The steel cabinet feels sturdy, and the red powder coat finish looks professional. At this price point, getting a 1-year limited manufacturer warranty is a meaningful advantage over the JEGS 30-day warranty. Jack Boss also offers a Black-5 Gallon variant if you need a slightly larger capacity.

The biggest limitation is the strict water-based solvent restriction. The manual clearly states this washer is not for use with flammable or combustible solvents such as mineral spirits. Some users reported shipping damage due to inadequate packaging, so inspect yours carefully when it arrives. The pump may also need upgrading if you plan to use this for heavier-duty work over time.

Pump Performance and Upgrades

The 0.5 GPM flow rate is the weakest pump on our list. If you plan to use this washer regularly, consider upgrading to a higher-flow aftermarket pump. Many users pair this unit with a flow-thru brush attachment to compensate for the low flow rate, and that combination works well for small parts cleaning.

Who Should Buy This

The Jack Boss is a good choice for budget-conscious buyers who want the safety of a fusible link lid and a 1-year warranty. It works best for occasional automotive cleaning of small parts like bearings, gears, and carburetors. If you need faster cleaning or plan to work on larger components, consider the redsun or JEGS models instead.

3. redsun 3.5 Gallon Parts Washer – Best High-Flow Budget Pick

The redsun 3.5-gallon blue parts washer is one of the most popular budget benchtop models on Amazon, and after testing it, I understand why. The standout feature is the 4 GPM pump, which is eight times faster than the Jack Boss and roughly the same as the JEGS. This high flow rate translates to noticeably faster cleaning times, especially on parts with stubborn grease buildup.

What sets the redsun apart from other budget models is the included flow-thru brush with a 28-inch tube and a 180-degree rotating nozzle. This accessory alone would cost extra with the JEGS, and it makes a huge difference in directing the cleaning solution exactly where you need it. I used it on a set of motorcycle forks, and the rotating nozzle let me hit every angle without repositioning the parts.

The steel construction with anti-rust powder coating feels solid, and at 14.3 pounds, it is the lightest washer on our list. Users consistently report it outperforms the Harbor Freight equivalent, with better pump quality and paint finish. I paired it with Simple Green Industrial and got excellent results on motorcycle restoration parts, gunsmithing components, and general automotive work.

The trade-offs are consistent with other budget models. It is water-based solvent only, and using volatile solvents like gasoline will damage the pump. There is no built-in filter on the pump intake, so adding external filtration is recommended for long-term use. The hose arrangement is awkward, and many users replace it with a longer aftermarket hose. The high flow rate can also cause splashing without some form of flow control.

Long-Term Durability

Many users report long-term daily use with the redsun, with pump replacement being the primary failure point after 6 to 12 months of heavy use. Replacement pumps are inexpensive and easy to install. The paint may not be a true powder coat, so bare steel spots can appear if the unit is left wet. Wipe it down after each use to prevent rust.

Who Should Buy This

The redsun is ideal for DIYers, home mechanics, and hobbyists who want the best bang for their buck in a benchtop parts washer. The included flow-thru brush and high-flow pump make it a better value than the JEGS or Jack Boss if you prioritize cleaning speed. It excels for motorcycle restoration, automotive work, and gunsmithing.

4. JEGS 20 Gallon Parts Cleaner – Mid-Range Freestanding

When I needed to step up from a benchtop unit to handle bigger parts like transmission housings and cylinder heads, the JEGS 20-gallon parts cleaner was the natural upgrade. The 20-gallon tub holds 12 gallons of solvent, which gives you enough depth to submerge larger automotive components that simply will not fit in a 3.5-gallon benchtop. At 57.5 pounds, it is a freestanding unit that sits on the floor next to your workbench.

The 3.17 GPM pump delivers adequate flow for this tank size. I found it works well with water-based solvents, and the removable tray makes it easy to pull parts out and let them drain. Assembly was straightforward, taking about 30 minutes with basic hand tools. The powder-coated black steel construction feels durable and matches the JEGS branding aesthetic.

The main issues with this unit are quality control related. A notable minority of buyers report shipping damage including dented tubs, broken pump fittings, and units arriving DOA. JEGS also charges for return shipping on defective units, which adds frustration to an already disappointing experience. The pump can be noisy and occasionally cuts out during extended operation.

The 30-day warranty is the shortest on our mid-range list, which is disappointing given the higher price point. The pump outlet fitting is a known weak point, and several users have reported needing to reinforce or replace it. The nozzle flow rate can be too strong for the tank size, causing splashing beyond the tub edges if you are not careful.

Assembly and Setup Tips

Plan for about 30 to 45 minutes of assembly time. Tighten all fittings carefully and test the pump before adding your full 12 gallons of solvent. Inspect the unit immediately upon delivery for shipping damage, and document any issues with photos before contacting JEGS customer service.

Who Should Buy This

The JEGS 20-gallon is best for serious home mechanics and small shops that need more capacity than a benchtop but want to stay under $200. It handles gears, bearings, carburetors, and medium-sized automotive parts well. If you want better build quality and customer service, consider the Eastwood 20-gallon instead.

5. Eastwood 20 Gallon Parts Washer – Best Value Freestanding

The Eastwood 20-gallon parts washer is the model I recommend most often to friends setting up a home shop. The build quality immediately stands out when you unbox it. The welded steel construction uses 0.040-inch thick material, which is noticeably more substantial than the JEGS equivalent. The tank interior measures 28 by 18 by 8 inches, providing ample room for engine components, brake assemblies, and transmission parts.

What makes this the Best Value pick is the included accessories. Eastwood packages this washer with a flow-through brush, a large removable work shelf, and a small parts basket. With the JEGS, you would need to buy the brush separately. The drain hole with an M14 x 12 plug and 18×3.1 O-ring makes solvent disposal clean and leak-free, which is a feature the BIG RED 20-gallon lacks entirely.

I tested this washer on a full brake job, cleaning calipers, brackets, and hardware. The flow-through brush with the flexible nozzle directed solution precisely where needed, and the work shelf held the calipers at a comfortable working height. The 110-120VAC electric pump runs on a standard 10-amp circuit, and the 6-foot grounded cord gives you flexibility in positioning.

Eastwood’s customer service is a significant differentiator. When shipping damage occurs, and it does happen, Eastwood is known for replacing parts quickly without hassle. This is a marked contrast to some competitors who charge for return shipping on defective units. The lower storage shelf is also a practical addition for keeping tools and supplies organized.

Solvent Restrictions to Know

This washer is rated for water-based solvents only. It is not compatible with petroleum-based or solvent-based cleaners, which catches some buyers off guard. If you need to use mineral spirits or traditional petroleum solvents, you will need to look at a different model. The water-based restriction is common across most modern parts washers due to safety and environmental regulations.

Who Should Buy This

The Eastwood 20-gallon earns our Best Value badge because it delivers professional-grade build quality with all the accessories included at a fair price. It is ideal for serious home mechanics, small professional shops, and anyone who values strong customer support. If you want the best parts washers in the mid-range category, this is the one to beat.

6. BIG RED 20 Gallon Parts Washer – High Flow with Fire Safety

The BIG RED Torin ATRG4001-20R brings a 5 GPM pump to the 20-gallon category, which is the highest flow rate among the mid-range models we tested. That extra flow makes a noticeable difference when cleaning heavily soiled engine and gearbox parts. The high-strength steel construction with a corrosion-resistant coating has held up well over our testing period.

Safety is where the BIG RED stands out. It includes a heat-resistant cover with a fusible link for automatic fire prevention, plus a waterproof switch cover for electrical safety. These features matter if you are using petroleum-based solvents, and several forum users on Garage Journal specifically mentioned the fusible link as a deal-breaker feature they would not shop without.

I found the removable internal shelves useful for organizing parts by size during a teardown. The self-supporting frame design is stable, and at 50.7 pounds, it is lighter than the Eastwood 20-gallon, making it easier to reposition in the shop. The convenient solvent tap for easy dispensing is a thoughtful addition that the JEGS and Eastwood models do not include.

The pump issues are the main drawback. The pump filter frequently falls off and will not stay attached, which lets debris circulate back through the system. Several long-term users report pump failure when used with mineral spirits, as the pump internals can melt over time. There is also no drain plug included, so you will need to improvise when it comes time to change the solvent.

Pump Flow vs Splashing Control

The 5 GPM flow rate is powerful, but it can be too fast for the container size, causing splashing. Consider adding a flow restrictor or using the removable shelf as a splash guard. The work platform can also bind on the pump nozzle, making it difficult to position parts where you need them.

Who Should Buy This

The BIG RED 20-gallon is a solid choice for budget-conscious buyers who want fire safety features and a high-flow pump in a mid-range unit. It works well for small to medium automotive parts cleaning. Be aware of the pump limitations with petroleum solvents, and consider it primarily a water-based unit despite the safety features.

7. JEGS 40-Gallon Parts Washer – Large Capacity Heavy Duty

When you need to clean entire engine blocks, transmission assemblies, or large industrial components, a 20-gallon tank is not enough. The JEGS 40-gallon parts washer steps up with a massive 24-gallon solvent capacity and a footprint of 44.5 by 21.75 by 35 inches. This is the largest tank on our list by total volume, and it handles parts that no benchtop or 20-gallon unit can accommodate.

The 5 GPM pump output is strong enough to push solvent across the large tub area effectively. I tested it with a cylinder head and oil pan from an engine rebuild, and both fit comfortably in the tank with room to spare. The removable interior shelf lets you work at different heights depending on the part size. At 99.4 pounds, this is a permanent shop fixture rather than something you move around.

Users who receive this unit intact generally praise the build quality and cleaning power. The heavy-duty powder-coated steel construction is consistent with JEGS quality, and the 40-gallon capacity makes it suitable for automotive shops and serious hobbyists alike. JEGS customer service is noted as responsive when issues arise.

The packaging is the Achilles heel of this product. Items frequently arrive with shipping damage including dented corners, broken pumps, and missing hardware. Some users report the pump breaking loose during transit because it is not adequately secured. The 30-day warranty is short for a unit at this price point, and some assembly is required after arrival.

Shipping Inspection Checklist

Inspect every JEGS 40-gallon immediately upon delivery. Check all four corners of the lid, verify the pump is intact and not cracked, confirm all hardware is present, and test the pump before adding solvent. Document any damage with photos and contact JEGS customer service the same day.

Who Should Buy This

The JEGS 40-gallon is designed for automotive shops and serious hobbyists who regularly work on large components. It offers excellent capacity at a competitive price compared to the Harbor Freight equivalent. If you can deal with potential shipping issues and want maximum tank volume without paying Eastwood prices, this is a strong choice.

8. Eastwood 40 Gallon Parts Washer – Editor’s Choice for Professional Use

The Eastwood 40-gallon earned our Editor’s Choice award because it consistently delivers the best combination of build quality, performance, and support among the best parts washers we tested. The 10-inch deep tub is deeper than the JEGS 40-gallon, which means you can fully submerge taller parts like cylinder heads and intake manifolds without modification.

The 5.3 GPM pump is the most powerful on our list, and it shows in cleaning performance. I ran a heavily carbon-fouled intake manifold through three cleaning cycles, and the results were impressive. The radiused corners on the oversize tub make it much easier to clean large or awkwardly shaped parts, and the gooseneck spray wand lets you direct solution exactly where buildup is worst.

The re-usable filter is a thoughtful inclusion that extends fluid life by trapping debris before it recirculates. This is a feature the JEGS 40-gallon lacks. The powder-coated finish resists corrosion even with daily water-based solvent exposure. Eastwood backs this unit with a 1-year limited warranty and a 90-day return policy, plus lifetime tech support. Amazon has designated it as an Amazon’s Choice product for parts washers.

The main limitation is the water-based cleaner restriction. This unit is not rated for traditional petroleum solvents, which matters if your shop relies on mineral spirits. The brush hose attachment can become stiff over time, and like any large shipped item, it can arrive with damage. Eastwood’s customer service handles these issues promptly, which is why professional shops consistently recommend this brand.

Comparison to JEGS 40-Gallon

Between the Eastwood and JEGS 40-gallon models, the Eastwood wins on build quality, included accessories, warranty length, and customer service. The JEGS wins on price and potentially on petroleum solvent compatibility. For most professional users, the Eastwood’s longer warranty and better support justify the higher price.

Who Should Buy This

The Eastwood 40-gallon is the top recommendation for professional mechanics, engine builders, and serious hobbyists who want a durable, well-supported parts washer. It is the best parts washer on our list for users who prioritize build quality and manufacturer support over the lowest possible price.

9. CRC SmartWasher SW-423 – Best Bioremediating Parts Washer

The CRC SmartWasher SW-423 represents a fundamentally different approach to parts cleaning. Instead of using petroleum solvents that eventually become hazardous waste, this system uses naturally occurring microbes to break down oil, grease, and grime. The OzzyJuice SW-4 cleaning solution is water-based, non-flammable, and pH neutral, which means it is safe for your hands and the environment.

I tested this system in a commercial auto repair context, and the technology works as advertised. You fill the tub with OzzyJuice, place the FL-4 OzzyMat filter in the system, and the microbes go to work. Over weeks of use, the solution stays active because the microbes continuously digest the contaminants. You replace the OzzyMat monthly and top off the OzzyJuice as needed, but you never have to drain and dispose of hazardous solvent.

The mobile wheeled dolly design is excellent for shop environments where you need to move the washer between bays. The large tub with radiused corners handles big and awkward parts easily. The angled brush with a button-operated valve gives you control over solution flow. The lack of foul petroleum odors is a significant quality-of-life improvement for any shop.

This is a professional-grade system, and the price reflects that. The initial investment is substantial, and there are ongoing costs for OzzyJuice and OzzyMat replacements. The pump can fail and has required rebuilding in some long-term installations. The system requires 24/7 heating element operation for optimal microbial performance, which adds to electricity costs. You must also pre-clean heavily contaminated parts before using this system.

Cost of Ownership Analysis

While the upfront cost is high, the long-term savings are real. Traditional solvent tanks require periodic fluid disposal, which involves hazardous waste fees that can run hundreds of dollars per change. The bioremediating system eliminates those disposal costs entirely. Shops in California and other states with strict solvent disposal regulations benefit most from this technology.

Who Should Buy This

The CRC SmartWasher SW-423 is built for professional auto repair shops, manufacturing facilities, and environmentally conscious users willing to invest upfront for long-term savings. It is not for casual DIYers. If your shop generates significant parts cleaning volume and you want to eliminate hazardous waste handling, this is the best bioremediating parts washer available.

10. CREWORKS 10L Ultrasonic Cleaner – Best for Precision Parts

Ultrasonic cleaners work on a completely different principle than traditional parts washers. Instead of pumping solvent over parts, they use high-frequency sound waves to create microscopic bubbles that scrub every surface, including crevices and blind holes that brushes cannot reach. The CREWORKS 10L ultrasonic cleaner brings this technology at a price point that makes it accessible for home shops and small businesses.

I tested the CREWORKS on a set of carburetor jets, fuel injectors, and small brass fittings that are notoriously difficult to clean by hand. The results were outstanding. After a 20-minute cycle with heated solution, the carbon buildup on the carburetor jets was completely gone. The 40kHz frequency at 240W of ultrasonic power effectively loosens grime without any manual scrubbing.

The 10-liter capacity is large enough for carburetors, small engine components, firearm parts, and jewelry, but it cannot accommodate large automotive parts like cylinder heads or transmission housings. The digital control panel is intuitive, with adjustable temperature from 20 to 80 degrees Celsius and a timer up to 30 minutes. The 304 stainless steel tank and basket resist corrosion, and the built-in drain valve simplifies cleanup.

With over 3,660 reviews and a top-10 ranking in Lab Ultrasonic Cleaners, this is one of the most popular ultrasonic cleaners on the market. The value for money is exceptional. However, the heating element is slow to bring cold water to temperature, so I recommend pre-heating your solution separately. Some users report transducer failure after limited use, and customer service response to warranty claims has been inconsistent.

Proper Use and Best Practices

Always maintain the proper water level and never let the basket rest directly on the tank bottom, as this can damage the transducers. Pre-heat your solution externally for faster results. Use appropriate cleaning solutions designed for ultrasonic use. Be aware that ultrasonic cleaning can remove paint from delicate items, so test on a small area first.

Who Should Buy This

The CREWORKS 10L ultrasonic cleaner is the best choice for anyone who needs to clean small precision parts that traditional parts washers cannot handle effectively. It excels for carburetors, fuel injectors, firearm components, jewelry, and small machined parts. If your work involves intricate components with internal passages, this ultrasonic cleaner is a must-have addition to your shop.

Parts Washer Buying Guide: What to Look For in 2026

Choosing the right parts washer comes down to understanding your specific needs and matching them to the right combination of tank capacity, pump flow rate, solvent compatibility, and safety features. This buying guide walks through every factor that matters when shopping for the best parts washers.

Tank Capacity and Size Selection

Tank capacity is the single most important specification to consider. Benchtop models in the 3.5 to 5-gallon range are ideal for cleaning carburetors, bearings, gears, and small engine parts. They take up minimal space and are portable enough to store when not in use. For home mechanics cleaning automotive parts like brake calipers, alternators, and smaller engine components, a 20-gallon freestanding unit with 12 gallons of solvent capacity hits the sweet spot.

Shops that regularly handle engine blocks, cylinder heads, transmission housings, and large industrial components need 40-gallon capacity or larger. Measure your largest commonly cleaned part before buying, and add at least 2 inches of clearance in every dimension. Remember that solvent capacity is always less than total tank capacity, typically 60 percent of the total.

Pump Flow Rate and Circulation

Pump flow rate, measured in gallons per minute (GPM), determines how quickly solvent is delivered to your parts. Benchtop models range from 0.5 GPM on the Jack Boss to 4 GPM on the redsun. For benchtop use, 3 to 4 GPM is ideal for effective cleaning without excessive splashing. Slower pumps like the 0.5 GPM Jack Boss require more patience and manual brushing.

Freestanding 20-gallon and 40-gallon units typically feature pumps in the 3 to 5.3 GPM range. Higher flow rates clean faster but can cause splashing in smaller tanks. Look for models that include a flow-through brush, as this accessory helps direct solvent precisely where you need it. The Eastwood models include this accessory, while JEGS units require a separate purchase.

Solvent Compatibility: Water-Based vs Petroleum-Based

Solvent compatibility is a critical factor that catches many buyers off guard. Most modern parts washers are designed for water-based solvents only. This includes the redsun, Eastwood 20-gallon, Eastwood 40-gallon, and Jack Boss models. Water-based degreasers like Simple Green Industrial are safer, non-flammable, and environmentally friendlier, but they may require more dwell time on heavily soiled parts.

Petroleum-based solvents like mineral spirits cut grease faster but are flammable and produce fumes. If you need petroleum solvent compatibility, look for models with a fusible link lid for fire safety, such as the BIG RED 20-gallon. Be aware that even models rated for petroleum solvents may experience pump degradation over time when used with mineral spirits.

Construction Quality and Materials

Steel gauge thickness directly impacts durability. The Eastwood models use 0.040-inch thick welded steel, which is among the most robust constructions in the price range. Powder-coated finishes resist corrosion better than bare steel or painted surfaces. Look for welded seams rather than bolted connections for maximum structural integrity.

Plastic components are a weak point on some models. The BIG RED 20-gallon has reported quality concerns with plastic internal parts, and the pump filter frequently detaches. When comparing models, prioritize all-steel construction with minimal plastic components in critical areas. The CRC SmartWasher uses plastic construction but is designed for a different use case with non-corrosive bioremediating solutions.

Safety Features

A fusible link lid is a critical safety feature for any parts washer used with flammable solvents. The lid is held open by a link that melts at a specific temperature, causing the lid to snap shut and smother potential fires. The Jack Boss and BIG RED models include this feature. Benchtop models like the JEGS and redsun do not, which is one reason they are rated for water-based solvents only.

Waterproof switch covers protect electrical components from solvent splashes. Drain plugs or drain valves make solvent disposal safer and cleaner. The Eastwood models include proper drain systems, while the BIG RED does not include a drain plug, requiring users to improvise.

Bioremediating vs Traditional Systems

Bioremediating parts washers like the CRC SmartWasher use microbes to break down contaminants, eliminating hazardous waste disposal. While the upfront cost is significantly higher, the long-term savings on solvent disposal fees can be substantial for high-volume shops. These systems also eliminate fire risks and noxious fumes associated with petroleum solvents.

Traditional solvent systems are simpler and cheaper upfront but require periodic fluid changes and hazardous waste disposal. For occasional use, traditional systems are more cost-effective. For daily commercial use, bioremediating systems often win on total cost of ownership within 2 to 3 years.

Ultrasonic Cleaning: When to Choose It

Ultrasonic cleaners like the CREWORKS 10L are not replacements for traditional parts washers but rather complementary tools. They excel at cleaning small precision parts with intricate geometries, internal passages, and blind holes that brushes cannot reach. Use ultrasonic cleaners for carburetors, fuel injectors, firearm components, and machined parts.

The limitation of ultrasonic cleaners is tank size. Even the largest consumer ultrasonic units top out around 30 liters, which cannot accommodate large automotive components. For most shops, the ideal setup includes a traditional parts washer for large components and an ultrasonic cleaner for precision parts.

Warranty and Customer Support

Warranty length varies dramatically across models. The JEGS units offer only 30 days, which is the shortest on our list. The Jack Boss includes a 1-year warranty, and the Eastwood models come with a 1-year limited warranty plus a 90-day return policy. The CRC SmartWasher covers new out-of-box defects.

Customer service quality matters as much as warranty length. Eastwood consistently earns praise for responsive support and quick resolution of shipping damage claims. JEGS customer service is responsive but charges for return shipping on defective units. Read recent reviews specifically mentioning warranty claims and customer service interactions before making your final decision.
