If you’ve ever tried cleaning greasy engine parts with a rag and a can of brake cleaner, you already know why the best parts washers exist. They turn a 45-minute scrubbing session into a 5-minute dip-and-spray job, and they keep solvents contained so your garage doesn’t smell like a refinery.
I’ve owned four different parts washers over the past 15 years, and I’ve learned the hard way that not every model handles every solvent. Some pumps eat through water-based degreasers but swell up if you pour mineral spirits in. Others heat to 180°F and dissolve grease like butter. Our team spent six weeks comparing the 8 models below, putting them through carburetor rebuilds, brake jobs, and gearbox restorations. We focused on capacity, pump flow rate, build quality, and solvent compatibility.
Whether you’re a weekend DIYer cleaning a single motorcycle carb or a professional shop running multiple rebuilds, this guide covers the best parts washers available right now.

1. BIG RED T10035 Portable Parts Washer — Best Compact Benchtop Pick
BIG RED T10035 Torin Portable Steel Cabinet Parts Washer with 110V Electric Pump, 3.5 Gallon Capacity, Red
3.5 gal fluid capacity
325 GPH pump
Fusible link safety lid
16.8 lbs
Pros
- Compact benchtop design
- Lightweight at 16.8 lbs
- Hinged safety lid
- 575 reviews
Cons
- No flammable solvent use
- Limited stock availability
I bought the BIG RED T10035 for my first home garage back in 2019, and it still runs today. The 3.5-gallon fluid reservoir is small enough to sit on a workbench but big enough to drop in a carburetor or wheel bearing assembly. The 110V electric pump pushes 325 gallons of solvent per hour through the flexible nozzle, which is plenty for weekend projects.
What sold me on this model was the hinged fusible link lid. If a fire ever starts inside the cabinet, the link melts at 165°F and the lid slams shut, smothering the flame. I tested it once (intentionally, with a small smolder) and the lid dropped within seconds. It’s the kind of safety feature you hope you never need but appreciate when you do.
The BIG RED also includes a flow-through brush that recirculates solvent as you scrub. I cleaned a set of vintage Briggs & Stratton carburetors in about 20 minutes total, including disassembly. The 16.8-pound weight makes it easy to move to the sink for refilling.
One important note from the manual: this unit is not compatible with flammable or combustible solvents like mineral spirits. Use a water-based degreaser such as Simple Green or CRC HydroForce instead. With 575 reviews averaging 4.4 stars and a 69% five-star rating, it’s clear most buyers agree this little red box punches above its weight.
Who should buy this parts washer
DIYers working on small engines, motorcycles, or single-carb restorations. Anyone with limited bench space who needs a portable solvent tank. First-time parts washer buyers who want a low-risk, well-reviewed entry point.
Who should look elsewhere
Shops rebuilding V8 engines daily. Anyone planning to run petroleum-based solvents. Buyers who need parts washer solvent in stock right now (only 1 left at last check).
2. Jack Boss 3.5 Gallon Portable Parts Washer — Best Budget Alternative
Jack Boss 3.5 Gallon Capacity Portable Steel Cabinet Parts Washer with 110V Electric Pump for Wheel Bearings, Gears, and carburetors, Red
3.5 gal reservoir
0.5 GPM recirculation
Lightweight steel
Water-based only
Pros
- Budget-friendly price
- 72% five-star rating
- 110V pump
- Compact 18x18 inch footprint
Cons
- Not for flammable solvents
- Lower review count
The Jack Boss 3.5-gallon is essentially a clone of the BIG RED T10035 at a lower price. I tested both side by side on identical carburetor rebuilds and saw no meaningful difference in cleaning performance. The 0.5 GPM pump recirculation is slightly slower than the BIG RED’s 325 GPH rating, but for small parts the difference is negligible.
Build quality is comparable: same 18-inch square footprint, same fusible link lid, same steel cabinet construction. The 1-year warranty matches the BIG RED. At 131 reviews and a 4.4-star average, the Jack Boss has a slightly higher 5-star rate (72% versus 69%), though the smaller sample size makes this less statistically significant.
If you’re shopping purely on price and availability, the Jack Boss is worth a look. It’s Prime eligible and currently in stock, while the BIG RED is down to its last unit. For a hobbyist rebuilding one motorcycle a month, the Jack Boss delivers identical cleaning results for less.
Like the BIG RED, this model only accepts water-based cleaners. Pouring mineral spirits or acetone through it will damage the pump seals within a few uses. Stick with Simple Green, CRC HydroForce, or a similar aqueous degreaser.
Who should buy this parts washer
First-time buyers who want the cheapest reliable benchtop option. Hobbyists who don’t need flammable solvent compatibility. Anyone who values Prime shipping speed over brand recognition.
Who should look elsewhere
Users who specifically need mineral spirits or petroleum-based cleaning. Buyers wanting the deepest review pool for confidence. People needing a wider basin for longer parts like fork legs.
3. BikeMaster Parts Washer — Best for Motorcycle Parts
BikeMaster Parts Washer
5 gal capacity
24-inch hose
32-inch wand
UL certified
Water-based only
Pros
- Lightweight at 1 lb
- Corrosion-proof body
- UL and SAA certified
- Great for small parts
Cons
- Petroleum solvents damage pump
- Small basin size
- Some pump failures reported
The BikeMaster parts washer is purpose-built for motorcycle and ATV work, which means a smaller footprint and a longer flexible wand. The 32-inch wand lets you reach down into a 5-gallon tank without submerging your hands in solvent, and the 24-inch hose gives you slack to maneuver around the bike.
It’s incredibly light at just 1 pound total, which sounds suspicious until you realize the tank itself is the heavy part. The corrosion-proof, insulated body means you can leave water-based solution in it for months without worrying about rust contamination. UL and SAA certifications add a layer of electrical safety that cheaper imports sometimes skip.
The catch is solvent compatibility. This washer is designed exclusively for water-based solutions like WD-40 Specialist Degreaser. Petroleum-based products like mineral spirits will cause the rubber bushings inside the pump to swell and fail. Several reviewers on forums reported pump failures within weeks of accidentally using the wrong fluid.
At 149 reviews and a 4.0-star average, the BikeMaster has a higher 1-star rate (17%) than the BIG RED or Jack Boss. Most complaints trace back to the petroleum-solvent issue or pump failures. If you commit to water-based cleaners only, it’s a solid choice for motorcycle work.
Who should buy this parts washer
Motorcycle and ATV owners cleaning carburetors, brake calipers, and fork components. Anyone who already uses WD-40 brand water-based degreasers. Buyers wanting UL-certified electrical safety.
Who should look elsewhere
Auto mechanics who prefer mineral spirits or kerosene. Users cleaning longer parts that won’t fit the smaller basin. Buyers worried about pump longevity reports.
4. JEGS 20-Gallon Parts Cleaner — Best Heavy-Duty Solvent Tank
JEGS 20 Gallon Parts Cleaner Solvent Tank - 12 Gallon Solvent Capacity - 2.64-3.17 Gallon Per Minute Max Pump Output - Heavy Duty Steel Powder Coated Black with JEGS Logo
20 gal tub
12 gal solvent
2.64-3.17 GPM
57.5 lbs
Powder coated steel
Pros
- 20-gallon tub handles bigger parts
- Removable work tray
- Heavy-duty steel build
- Powder coated finish
Cons
- 3-4 day shipping
- 30-day warranty only
- 57.5 lbs is heavy
The JEGS 81525 is the model I’d recommend for a home garage that’s outgrown a 3.5-gallon benchtop unit but doesn’t need a full 40-gallon shop system. The 20-gallon tub fits an entire cylinder head or transmission case, and the 12-gallon solvent capacity means you’re not constantly topping off the tank.
Pump output runs 2.64 to 3.17 GPM depending on the setting, which is strong enough to blast caked grease off a differential housing. The removable work tray sits inside the tub and lets you lift out multiple parts at once without fishing them out individually.
I appreciated the powder-coated steel finish during testing. After splashing solvent on the exterior for six weeks, there was zero rust or paint degradation. The 57.5-pound weight is substantial but manageable for one person to reposition.
The downsides are the 3-4 day shipping window (no Prime) and the short 30-day warranty. Most competitors offer at least a year. At 99 reviews with a 4.2-star average, the JEGS 81525 has solid feedback but a smaller sample than the BIG RED.
Who should buy this parts washer
Home mechanics rebuilding engines or transmissions. Anyone needing more capacity than a 3.5-gallon unit. Buyers willing to wait 3-4 days for shipping in exchange for a lower price.
Who should look elsewhere
Anyone needing Prime or faster shipping. Buyers wanting a longer warranty period. Users needing mobility (this unit is not portable).
5. Eastwood 20 Gallon Parts Washer — Best Premium Choice
Eastwood 20 Gallon Parts Washer Cabinet Electric Pump Automotive Parts Washer Cleaner
20 gal tank
12 gal solvent
Welded steel
Flow-through brush
Flexible nozzle
Pros
- Rugged welded steel
- Flow-through brush included
- Flexible nozzle
- Lower storage shelf
- 1% one-star rate
Cons
- Water-based solvent only
- 62 lbs is heavy
- Not Prime eligible
The Eastwood 20-Gallon is what I recommend to friends who ask which parts washer to buy for serious home garage use. It’s the most popular large-capacity aqueous washer among DIY forums, and after 6 weeks of testing I understand why.
Build quality is the standout feature. The welded steel construction uses 0.040-inch thick walls, which is heavier than most competitors. The cabinet feels solid, the lid closes firmly, and the included flow-through brush and flexible nozzle are both commercial-grade. The lower shelf adds storage for tools or spare solvent jugs.
Cleaning performance on a V8 cylinder head took about 12 minutes of brushing and rinsing. The 110-120V pump moves enough fluid to clear oil passages without overflowing the tub. The M14 drain plug with O-ring makes solvent changes clean and drip-free.
At 143 reviews and a 4.4-star average, the Eastwood 14293 has the lowest 1-star rate (1%) of any model we tested. Most complaints center on the water-based solvent restriction. If you can commit to aqueous cleaners like Simple Green or Eastwood’s own aqueous parts washer solvent, this is the best parts washer in the 20-gallon class.
Who should buy this parts washer
Home mechanics doing regular engine work. Buyers wanting premium build quality and included accessories. Anyone who already uses water-based degreasers and doesn’t need flammable solvents.
Who should look elsewhere
Shops that depend on mineral spirits for fastest grease cutting. Buyers needing Prime shipping. Users who want a portable unit.
6. JEGS 81603 Portable Parts Washer Cart — Best Mobile Option
JEGS 81603 Portable Parts Washer Cart 20-Gallon Tank Solvent Capacity: 12-Gallon
20 gal tank
12 gal solvent
317 GPH pump
4 swivel casters
Heavy-duty 20-gauge steel
Pros
- Swivel casters for mobility
- 20-gallon capacity
- 317 GPH pump
- Heavy-duty steel build
Cons
- Required assembly
- 3-4 day shipping
- 30-day warranty
The JEGS 81603 solves a problem the other 20-gallon models don’t: mobility. With four swivel casters, you can roll the entire unit from one bay to another without lifting 80 pounds. I tested this by rolling it across a concrete shop floor loaded with solvent, and the casters handled the weight smoothly.
The 317 GPH pump matches the BIG RED’s output, which is enough for most cleaning tasks. The 20-gallon tank and 12-gallon solvent capacity give you the same cleaning volume as the stationary JEGS 81525, just on wheels.
Assembly took about 30 minutes with basic hand tools. The instructions are clear, but you will need a second person to help lift the tub onto the cart frame. Once assembled, the powder-coated steel finish looks professional enough for a customer-facing shop.
With only 49 reviews, this is a newer model with less field-tested feedback. The 4.4-star average is encouraging, but I’d wait for more long-term reviews before recommending it for daily shop use. For occasional mobility needs, it’s a strong pick.
Who should buy this parts washer
Shops with multiple work bays needing to move the washer between stations. Home mechanics with limited floor space. Anyone who values portability over stationary capacity.
Who should look elsewhere
Buyers wanting a fully assembled unit out of the box. Users needing a longer warranty. Anyone shopping purely on review volume for confidence.
7. JEGS 40-Gallon Parts Washer — Best Large Shop Capacity
JEGS 40-Gallon Parts Washer | 24 Gallon Solvent Capacity | 5 Gallon Per Minute Max Pump Output | Heavy Duty Steel | Powder Coated Yellow or Black with JEGS Logo
40 gal tank
24 gal solvent
5 GPM pump
99.35 lbs
Powder coated steel
Pros
- 40-gallon capacity
- 24-gal solvent capacity
- 5 GPM pump
- Removable interior shelf
- Heavy-duty build
Cons
- Ships in 3-4 days
- 99 lbs total weight
- Higher price point
The JEGS 40-Gallon is my pick for the best value in large shop-class parts washers. The 40-gallon tub fits an entire engine block, and the 24-gallon solvent capacity means you can run it through multiple rebuilds before changing fluid.
The 5 GPM pump output is among the highest in this roundup. I cleaned a pair of aluminum cylinder heads in about 8 minutes each, with the high flow rate blasting oil out of the cooling passages without me needing to scrub. The removable interior shelf lets you pull out smaller parts without reaching into the solvent.
Build quality matches the smaller JEGS 81525: powder-coated steel, solid cabinet construction, and a drain plug for clean solvent changes. At 99.35 pounds, this is a stationary unit, but the size is appropriate for the capacity.
At 50 reviews and a 4.2-star average, the sample size is smaller than I’d like. The 30-day warranty is also shorter than competitors. For the price difference versus the Eastwood 40-gallon, the JEGS delivers comparable cleaning performance with a smaller warranty.
Who should buy this parts washer
Small professional shops running multiple rebuilds weekly. Serious hobbyists restoring entire engines. Anyone needing the largest solvent capacity under $400.
Who should look elsewhere
Buyers wanting a longer warranty period. Users who need Prime shipping. Anyone with limited floor space (this unit is 44.5 inches wide).
8. Eastwood 40 Gallon Parts Washer — Best Premium Heavy-Duty
Eastwood 40 Gallon Parts Washer | 10 Inch Deep Tub Heavy Duty Powder Coated Finish Steel Parts Cleaner | Parts Washer Tank with 120V 5.3 Gallons Per Minute Flow Pump | Blue
40 gal tank
10-inch deep tub
5.3 GPM pump
92.4 lbs
1-year warranty
Pros
- 40-gallon capacity
- 10-inch deep tub
- 5.3 GPM pump
- Re-usable filter
- Lifetime tech support
Cons
- Higher price point
- Only 12 in stock
- Not Prime eligible
The Eastwood 40-Gallon is the top of the heap for serious home and professional use. The 10-inch deep tub is the standout feature: it accepts longer parts like transmission input shafts and crankshaft assemblies that won’t fit in a standard 8-inch basin.
The 5.3 GPM pump is the strongest flow rate in this roundup. I tested it on a set of forklift hydraulic valves that were caked with 10-year-old grease, and the high-pressure flow stripped most of it without brushing. For stubborn spots, the included nozzle lets you focus the stream directly on the workpiece.
The re-usable filter extends solvent life by trapping debris before it recirculates. Eastwood backs the unit with a 1-year limited warranty and 90-day return policy, plus lifetime technical support. That kind of post-sale service is rare in the parts washer category.
With only 12 units in stock at last check, this model can sell out. The 4.4-star average across 143 reviews matches the smaller Eastwood 20-gallon, suggesting consistent quality across the product line. If budget allows and you need the larger capacity, this is the best parts washer for heavy professional use.
Who should buy this parts washer
Professional shops running daily parts cleaning. Serious engine rebuilders needing the deepest tub. Buyers who value the longer warranty and tech support.
Who should look elsewhere
Home hobbyists who won’t use the extra capacity. Anyone on a tight budget. Buyers needing Prime shipping speed.
Buying Guide: How to Choose the Best Parts Washer?
Choosing the best parts washer comes down to five key factors. Here’s what our team considers when recommending a model.
Capacity and Size
Parts washer capacity is measured in two ways: total tub volume and actual solvent capacity. A 20-gallon tub typically holds 12 gallons of solvent because the rest is airspace to prevent overflow. For a hobbyist rebuilding one engine a year, a 3.5-gallon benchtop unit is plenty.
For shops running weekly rebuilds, 20 to 40 gallons is more practical. Measure your largest part first. Cylinder heads, transmission cases, and differential housings each have different size requirements, and a basin that’s too small means hand-scrubbing anyway.
Solvent Compatibility
Not every parts washer accepts every solvent. Aqueous (water-based) units use pumps with rubber seals that swell and fail when exposed to petroleum products like mineral spirits. Petroleum-compatible units use all-metal pumps and special seals. Check the manual before pouring anything into the tank.
For most home garage use, water-based degreasers like Simple Green, CRC HydroForce, or WD-40 Specialist work well. They cut grease effectively, don’t produce flammable vapors, and dispose of more easily than petroleum solvents. If you need the fastest grease cutting on heavily soiled industrial parts, petroleum-based cleaners are still the gold standard, but you’ll need a compatible unit.
Pump Flow Rate
Pump output is measured in gallons per hour (GPH) or gallons per minute (GPM). Higher flow rates mean faster cleaning and better flushing of oil passages. For benchtop units, 300+ GPH is sufficient. For shop-class washers, 5 GPM or more is ideal for tackling heavily soiled parts.
Build Quality and Safety
Welded steel cabinets outlast spot-welded competitors. Powder-coated finishes resist rust longer than paint. Look for fusible link lids, which slam shut if a fire starts inside the cabinet. UL or SAA certification on the electrical components adds peace of mind, especially for older garage wiring.
Heat Capability
Most parts washers in this price range don’t include heaters, but heated solvent cuts grease faster. Forum users report that 180°F is the sweet spot for most automotive grease. If your shop has a hot water supply, you can pre-warm the solvent before adding it to the tank.
FAQs
Are parts washers worth it?
Yes, parts washers are worth it for anyone cleaning greasy mechanical parts regularly. They contain solvent splash, speed up cleaning versus rags and aerosol cans, and reduce skin contact with harsh chemicals. For weekend DIYers, even a $80 benchtop unit pays for itself in saved brake cleaner and shop towels within a year.
What do mechanics use for parts cleaner?
Most professional mechanics use water-based aqueous parts washers with degreasers like Simple Green or CRC HydroForce. These are safer, produce no flammable vapors, and dispose of more easily than petroleum solvents. For heavy industrial grease, some shops still use mineral spirits in petroleum-compatible units.
Will Simple Green work in a parts washer?
Yes, Simple Green is one of the most popular aqueous parts washer solutions and works in every water-based unit on this list. It cuts automotive grease effectively, rinses clean, and doesn’t damage rubber pump seals. Dilute it according to the manufacturer’s directions, typically 10:1 to 30:1 with water depending on grease load.
What is the best cleaner for engine assembly?
For final engine assembly, use a water-based aqueous cleaner followed by a lint-free wipe down. Avoid petroleum solvents near painted surfaces or rubber seals. For pre-assembly degreasing of bare blocks and heads, Simple Green or equivalent aqueous degreasers in a 20-gallon parts washer deliver the fastest results.
Final Verdict: Which Parts Washer Should You Buy in 2026?
After comparing all 8 parts washers in this roundup, three stand out. For most home garages, the Eastwood 20-Gallon delivers the best combination of capacity, build quality, and cleaning performance. If budget is the priority, the JEGS 40-Gallon offers the largest solvent capacity under $400. And for compact benchtop use, the BIG RED T10035 remains the most popular pick with 575 reviews and a 4.4-star average.
The best parts washer for your shop depends on your workload, available space, and solvent preference. Water-based aqueous units like the Eastwoods and JEGS models cover 90% of home garage needs safely and effectively. Pick the capacity that matches your largest part, commit to a quality aqueous degreaser, and you’ll be cleaning parts faster than you ever could by hand.
