Dom, I am not sure if they carry it in Kallyfornia, but Graingers use to have a Graymills product I used a lot. It was called Agitene, and Super Agitene solvent. It had higher flash points, and at one time had lanolin in it even, to help your hands, as well as a anti flash rust agent. Check your local Grainger to see.

Also ZEP products. Usually they have a lot of commercial fluids. They have always had a good product, and usually have distribution in larger cities.

Neither of these two are cheap, but usually real good stuff. Good luck..
