Engine cleaning can turn into a messy, frustrating job without the right equipment. Grease and grime stick to every surface, and trying to clean engine parts with just rags and spray degreaser rarely gets the job done properly. That is where a quality parts washer becomes essential for any garage or workshop.
A parts washer is a specialized cleaning station designed to remove oil, grease, and contaminants from engine components using solvents or aqueous solutions. These machines come in various sizes and configurations, from compact benchtop units perfect for small parts to large floor-standing cabinets capable of handling engine blocks. When searching for the best parts washers for engine cleaning, factors like tank capacity, pump flow rate, and build quality make all the difference in performance and longevity.
We spent weeks researching and analyzing user feedback on dozens of models to find the most reliable options for different needs and budgets. Our team focused on real-world performance, build quality, and value to help you make the right choice for your workshop.

1. JEGS 20 Gallon Parts Cleaner Solvent Tank
- 20 gallon tub with 12 gallon solvent capacity
- Compact design saves workbench space
- Removable tray for versatility
- Vital tool for cleaning and degreasing parts
- Heavy at 57.5 pounds
- Not Prime eligible
The JEGS 20 Gallon Parts Cleaner delivers exactly what most home mechanics need for routine engine cleaning work. Its 12-gallon solvent capacity handles everything from carburetor components to cylinder heads, while the removable work tray keeps smaller parts organized during cleaning sessions.
Our research shows users particularly appreciate how this unit fits comfortably in smaller workshops without sacrificing cleaning capability. The powder-coated black finish holds up well against solvent splashes, and the integrated pump provides steady flow for thorough degreasing. At 57.5 pounds, it stays planted during use but remains movable when needed.
One standout feature is the flexibility the removable tray offers. Mechanics working on multiple components can separate parts by size or cleaning priority, making reassembly more organized. The pump output of 2.64 to 3.17 GPM provides adequate pressure for most cleaning tasks, though professional shops might want something with higher flow for faster turnaround.
The compact footprint measures well for garage workbenches, and users report the unit operates quietly compared to larger industrial models. JEGS includes a 30-day manufacturer warranty, which some buyers note feels short for equipment at this price point.
Who Should Choose This Model
Home mechanics and small shop owners who need reliable parts cleaning without occupying excessive floor space will find the JEGS 20 Gallon ideal. It handles most automotive components including engine blocks, transmission parts, and brake assemblies with room to spare.
Potential Drawbacks
The 57.5-pound weight makes it less portable than benchtop alternatives. Users needing to move the washer between job sites might find this cumbersome. Additionally, the lack of Prime shipping means longer wait times compared to other options.
2. Jack Boss 3.5 Gallon Portable Steel Cabinet Parts Washer
- Lightweight and portable design
- Prime eligible
- 110V electric pump recycles liquid
- Hinged fusible link lid for fire safety
- 1 year limited warranty
- Not for use with flammable solvents
- Small 18x13.5x9 inch work basin
The Jack Boss 3.5 Gallon Parts Washer offers an affordable entry point for mechanics who need basic parts cleaning capability without the commitment of a larger unit. Its compact benchtop design fits easily on standard workbenches, making it ideal for smaller garages or occasional use.
Users consistently praise the Prime eligibility and fast shipping, which gets you cleaning parts within days rather than weeks. The 110V electric pump recycles cleaning solution at half a gallon per minute, which works well for carburetors, wheel bearings, and smaller engine components.
Safety features include a hinged lid with fusible link that closes automatically in case of fire. This detail shows thoughtful engineering for a budget-priced unit.

Best Use Cases
DIY mechanics working on motorcycles, small engines, or automotive subassemblies will find this unit perfectly sized. Carburetor cleaning, gear degreasing, and bearing cleaning all fit comfortably within its capabilities. The portability allows moving it between locations as needed.
Important Limitations
This unit is explicitly designed for water-based cleaners only, not flammable solvents like mineral spirits. Using prohibited solvents can damage the pump and create fire hazards. The 3.5-gallon capacity also requires more frequent solvent changes compared to larger tanks.
3. VEVOR 5-Gallon Portable Automotive Parts Cleaner
- Electric filtration pump with mesh filter
- Adjustable gooseneck tube
- Rust resistant powder coating
- Ideal for small parts cleaning
- Low 0.4 GPM flow rate
- Only 10 reviews available
The VEVOR 5-Gallon Parts Washer brings essential cleaning capability in an ultra-portable package weighing just 15 pounds. Its electric filtration pump circulates cleaning solution through a mesh filter, helping extend solvent life by trapping debris before it reaches the pump.
Flexible gooseneck tubing allows directing flow precisely where needed, covering parts surfaces completely.

Small Shop Benefits
Auto repair shops handling carburetor rebuilds, valve assemblies, and transmission components will appreciate the space-saving design. The circulating pump system reduces solvent waste, making it economical for businesses watching operating costs.
Capacity Considerations
The 5-gallon tank capacity requires more frequent solvent changes than larger units, which impacts overall cleaning efficiency for high-volume work. Mechanics tackling multiple engine rebuilds might prefer a larger capacity model to minimize downtime.

- Environmentally friendly water-based cleaning
- 325 GPH pump
- Spacious work basin

8. JEGS 40-Gallon Parts Washer
- 40 gallon capacity for large parts
- Removable interior shelf
- Heavy duty steel construction
- Good value for size
- Compact space-saving design
- Poor packaging causes shipping damage
- Pump may arrive broken
- 30 day warranty only
The JEGS 40-Gallon Parts Washer offers impressive capacity for shops handling substantial engine components. With 24 gallons of solvent capacity and a 5 GPM pump, this unit delivers the flow and volume needed for serious cleaning work on large parts.
Our analysis of 50 reviews shows strong appreciation for the removable interior shelf that adds versatility when organizing parts of different sizes. The heavy-duty steel construction provides confidence for long-term use, though the 99.35-pound weight means you will want to position this unit carefully before filling.
Compact design considerations mean this floor-standing unit occupies minimal footprint relative to its capacity. At 44.5 x 21.75 x 35 inches, it fits through standard doorways while offering generous internal workspace.
Users report JEGS customer service responds well to damage claims, replacing broken pumps and damaged components promptly. The 30-day manufacturer warranty feels short for equipment at this price point, however.
High Volume Cleaning
Professional shops and engine builders will appreciate having 24 gallons of cleaning solution available, reducing the frequency of solvent changes. The 5 GPM pump flow handles demanding cleaning tasks efficiently.
Shipping Considerations
Packaging quality appears inconsistent, with multiple reports of dents, broken pumps, and missing hardware upon delivery. Ordering with proper shipping protection or buying from local suppliers might mitigate these risks.
Buying Guide: How to Choose the Best Parts Washer for Engine Cleaning
Selecting the right parts washer involves matching your specific cleaning needs with features that matter most for your workflow. Consider these essential factors before making your investment.
Tank Capacity and Work Area
Tank capacity directly impacts what size components you can clean effectively. Benchtop models like the Jack Boss 3.5 Gallon handle small parts such as carburetors, bearings, and gears. Floor-standing units like the Eastwood 40 Gallon accommodate engine blocks, transmission cases, and cylinder heads.
Consider your typical workload when choosing capacity. A 20-gallon unit works well for most home mechanics tackling occasional projects. Professional shops or engine builders should consider 40-gallon capacity to avoid the frustration of undersized basins.
Pump Flow Rate and Performance
Pump flow rate, measured in GPM (gallons per minute), determines cleaning speed and effectiveness. Budget units like the VEVOR 5-Gallon offer 0.4 GPM, adequate for light cleaning. Mid-range models like the JEGS 20 Gallon provide 2.64 to 3.17 GPM for reasonable flow.
Higher flow rates like the Redsun’s 4 GPM or Eastwood 40 Gallon’s 5.3 GPM deliver faster, more thorough cleaning. These higher flows become essential when cleaning multiple parts or heavily soiled components. Look for GPH (gallons per hour) ratings as well, with the OEMTOOLS model offering 325 GPH for substantial cleaning power.
Solvent Compatibility
Understanding solvent compatibility prevents equipment damage and safety hazards. Many units, including all Eastwood models, are designed specifically for water-based cleaners only. Using flammable solvents in these units can damage pumps and create fire risks.
Traditional solvent-based cleaners like mineral spirits provide aggressive degreasing but require proper ventilation and disposal. Water-based aqueous solutions offer environmental benefits and work well with proper degreasing additives. Check manufacturer specifications carefully before selecting cleaning solutions.
Build Quality and Durability
Steel construction thickness and weld quality determine how well a parts washer survives daily shop use. Welded steel construction, like that found on Eastwood models, generally outperforms spot-welded sheet metal alternatives. Powder coating protects against rust and solvent damage.
Consider weight as an indicator of build quality. The Eastwood 40 Gallon at 92.4 pounds versus the Redsun at 14.3 pounds reflects their different intended use cases. Professional shops benefit from heavier, sturdier units that stay planted during aggressive cleaning.
Portability and Workspace Requirements
If you need to move your parts washer between locations or work areas, consider weight and mobility features. The OEMTOOLS 20-Gallon includes built-in casters specifically for this purpose. Benchtop models like the Jack Boss and VEVOR units offer easy repositioning at under 20 pounds.

Additional Features Worth Considering
Flow-through brushes attach directly to solvent lines, providing targeted scrubbing action. Removable shelves and parts baskets keep components organized during cleaning. Drain plugs simplify solvent disposal, while filtration systems extend solution life.
Warranty length and manufacturer support matter for long-term ownership. Eastwood offers lifetime tech support, while many budget brands provide only 30-day coverage. Consider total cost of ownership including solvent usage and replacement parts availability.
FAQs
What is the best thing to clean engine parts with?
The best cleaning solution depends on your parts washer type and the level of contamination. Water-based aqueous cleaners work well for most engine components when combined with proper degreasing additives. For heavily soiled parts with baked-on grease, solvent-based cleaners provide more aggressive cleaning action. Always check your parts washer manufacturer specifications to ensure compatibility, as many units are designed for water-based solutions only.
What do mechanics use for parts cleaner?
Professional mechanics typically use aqueous parts washers with biodegradable cleaning solutions for environmental compliance and safety. Many shops have transitioned from traditional solvent tanks to water-based systems that still deliver effective cleaning when paired with quality degreasers. Common solutions include water-soluble degreasers, citrus-based cleaners, and alkaline washing compounds. The specific choice depends on local regulations, part materials, and contamination levels.
What is the best parts washer?
The best parts washer depends on your specific needs. For professional shops handling large components, the Eastwood 40 Gallon offers excellent capacity and build quality. Home mechanics might prefer the Redsun 3.5 Gallon for its combination of portability and 4 GPM flow rate. Budget-conscious buyers should consider the Jack Boss 3.5 Gallon for basic cleaning needs. Key factors include tank size, pump flow rate, solvent compatibility, and build quality.
Are ultrasonic cleaners good for engine parts?
Ultrasonic cleaners work excellently for small, detailed engine components like carburetors, fuel injectors, and valve train parts. The ultrasonic cavitation process reaches into crevices and passages that traditional spray washers cannot access. However, ultrasonic cleaners require parts to fit into relatively small tanks, making them impractical for engine blocks or large castings. For comprehensive engine cleaning, many shops use both ultrasonic units for small parts and traditional spray or immersion washers for larger components.
Conclusion
Finding the best parts washer for engine cleaning requires matching your specific needs with the right combination of capacity, flow rate, and build quality. Our top pick, the Eastwood 40 Gallon, delivers professional-grade performance for shops handling substantial components. The Redsun 3.5 Gallon offers outstanding value for home mechanics wanting effective cleaning without breaking the budget.
For those just starting or with limited space, the Jack Boss 3.5 Gallon provides an affordable entry point with reliable performance. Whatever your needs, investing in a quality parts washer transforms engine cleaning from a messy chore into an efficient part of your maintenance workflow.
