Simple Green is another staple in our shop, valued for its balance of cleaning power and safety. This non-toxic, biodegradable formula tackles grease, grime, and dirt without the harsh fumes or skin irritation that come with many stronger solvents. It’s safe for use on metal, plastic, and painted surfaces, which makes it a versatile choice for everything from cleaning hand tools to degreasing parts before reassembly. While it’s tough enough for heavy shop use, Simple Green is also gentle enough to use in a parts washer, making it a dependable option when you want effective cleaning without compromising on safety or environmental impact.

Harbor Freight Parts Washer Solvent/Degreaser
The Harbor Freight Heavy-Duty Degreaser earns its place in the shop as a go-to for tackling the toughest grime without harsh chemicals. It quickly cuts through grease on machinery, tools, concrete floors, and more—yet remains biodegradable and nonflammable, making it safer for shop environments. For heavy-duty parts washer solvent needs, this formula holds its own in parts cleaning because it effectively strips oils and coatings while still being environmentally considerate. If you’re looking for a powerful cleaner that balances strength and shop-safety, this degreaser is a practical, low-cost workhorse.
Honorable Mention: Kerosene
Kerosene has been a traditional choice for cleaning and degreasing metal parts for decades, and it still earns an honorable mention for its effectiveness. It cuts through heavy grease and oil with ease, making it useful for stubborn buildup that water-based cleaners struggle to remove. While kerosene works well as a parts washer solvent, it does come with trade-offs—its strong odor, flammability, and need for proper ventilation mean it’s best suited for outdoor or well-ventilated spaces. For those willing to work within those limitations, kerosene remains a powerful, budget-friendly option for deep-cleaning metal components.
Important – make sure your parts washer is rated for petroleum-based solvents before running kerosene through your pump!

Choosing the right parts washer solvent can make all the difference in how efficiently you clean and maintain your tools, equipment, and workspace. From versatile shop staples like Purple Power and Simple Green to heavy-duty options like the Harbor Freight Degreaser, there’s a solution to fit every cleaning challenge. Even traditional choices like kerosene still have their place for specific, heavy-build-up jobs.
By matching the solvent to the task at hand, you’ll extend the life of your equipment, keep your shop running smoothly, and make every cleanup faster and more effective.
