There is no universal parts-washer fluid. Cold solvent tanks need a compatible petroleum solvent; heated or recirculating aqueous machines need low-foam detergent; bioremediating systems need their maker’s fluid. Never pour a random degreaser into a washer—the pump, seals, metallurgy, fire rules and waste stream all matter. These current products are grouped by washer chemistry so you can choose a real match for the machine.

Buying tips
- Read the washer manual and safety data sheet before filling it; solvent, aqueous and bioremediating fluids are not substitutes.
- Keep chlorinated brake cleaner, gasoline and mixed waste out of the tank—those combinations create safety and disposal problems.
- Dry cleaned ferrous parts promptly after aqueous washing and use the corrosion protection specified for the job.
