I just bought a 20 gallon parts washer and it's only supposed to use cleanign solutions between 6 adn 8 PSI. i was hoping to use the stuff from my degreaser bath (kerosene and biodegradable Degreaser) but have no idea what PH it has. What solutions has everyone else used? I'll be using it mostly for greasy parts like carbs, brackets, etc...

Without getting too technical, pH is a measure of acidity or alkalinity (acid/base). Neutral is 7(water), each number is a 10 fold increase so that 6 is 10x as acidic as 7, 5 is 100 times as acid ,etc. so looking for compounds bewteen 6 and 8 is pretty much looking for neutral compounds. Your degreaser should have that info available either on the label or through the manufacturer. You can check out their MSDS (Material Safety Data Sheet) on line and find this,too. You could also call the parts washer manufacturer and ask for specific product recommendations. Not to your point at all, but it would be interesting to know if the recommendation on pH was made for operator and environmental safety considerations, or because your equipment has some factor that will not stand up to caustic material exposure. Let us know what you find out about the cleaners.

Kerosene is neutral (pH=7), because it's an organic compound. The degreaser is the worry -- assuming it's some kind of detergent in water, pH might be 10.

I use a low-volatility paint thinner, which works fine on greasy stuff, lasts a long time, and is fairly cheap.
