What solvent for parts washer?

Bill, you should really get hold of someone who has some MODERN safe degreaser. They have come light years ahead of what they once were. No need to worry about them being flammable, or hurting your skin. Also, on every parts washer I have ever seen.......at least since the 1980s they clearly say not to use petroleum based cleaners as that will hurt the pump.

I am telling you, if you have not tried it, you need to hook up with someone who has and see what I am talking about. I was like you and only used mineral spirits. I will never again use it.

Screw that water-based degreaser! Petoleum-based works one helluva lot better. I'm not going to be exposing my skin to it because I'm going to be wearing triple-layer rubber gloves, and I don't intend to spill it. Unlike water-based cleaners, you can use petroleum-based cleaner forever by simply decanting the liquid off the accumulated solids. Water based cleaners actually create more pollution because you have to dispose of them when they become ineffective.

But if you really believe that stuff, RRR, then our California Governor Jerry Brown has a position open in the state's Department of Environmental Protection, and I think you should apply for it.
