How to Choose the Right Solvent For Parts Washer

Different cleaning applications require different solvents. So, how do you know which one is right for your parts washer? Let me answer this question with another question. What kind of cleaning task do you need to do?

High To Medium Usage

If you intend to use your parts washer for all your cleaning jobs, go with a petroleum-based solvent like the B’laster. This is a heavy-duty solution that is specifically intended to be used in a parts washer only.

To get the most out of your cleaning solvent; it is better to go with industrial-grade products, especially if you are running a repair shop or a home garage. For a big facility that constantly decreases and maintains automotive parts, your need something strong.

Medium To Low Usage

For less frequent jobs, you don’t need a powerful solvent. This means anything with an eco-friendly tag like the Oil Eater or the Spring Green will be more than enough.

FAQs About Parts Washer Solvent

What solvent to use on a new parts cleaner?

If you don’t want to smell up the garage too much, I would suggest you go with something that has a low odor and is biodegradable.

Are water-based cleaners any good?

In terms of cleaning strength, water-based cleaning agents won’t perform as well as petroleum-based cleaning agents. With that begin said, most cleaning jobs won’t require the need for a petroleum-based cleaner.

Can I use mineral-based parts cleaning fluid for other cleaning tasks?

Aside from metal parts, you can use these cleaning agents to clean hard plastic objects.

Can I use a petroleum-based solvent on a parts washer designed for water-based solvent?

No. If you do that, the pump housing of your parts washer will distort, thus rendering the parts washer useless. It can also create a fire hazard since these are flammable liquids.

Can I use kerosene as a parts cleaner?

The usage of kerosene is quite common and has been in use in workshops for a long time. This is mainly because of the low cost. However, when it comes to removing bearing grease, kerosene is not very useful.

What Is The Best Solvent For Grease?

Alcohol is one of the best solvents for grease or dissolving fat. The grease particles are broken into small particles by the alcohol. Again, the alcohol molecules themselves surround the tiny particles of oil, which keeps the tendency to dissolve the fat quickly.

You can cut the grease almost immediately by using alcohol. But the thing that should be kept in mind is that it should be used only on non-porous surfaces like metal, glasses, etc.
