Fruita CO | The old hot tanks used stuff called Oakite, which was caustic soda. My old machine shop friend had a tank big enough for a D9 Cat block. When he closed down and had to move out of the building he just gave the tank to an oil field shop...they let me use it a couple times for blocks and heads, then it just kinda went away...I didn't ask, they didn't tell...
Last I knew, when you buy Oakite there's a EPA manifest that has to stay with it all the way to a hazmat disposal facility.
A truck shop here got busted for dumping hazardous waste down prairie dog holes in an open field by the shop...didn't end well for them.
The rotary cabinet cleaners I think just bake the paint and gunk off like an oven then blast it with hot water. I have had heads cleaned in them and you have to chase out all the threaded holes, they come out full of crud. Not as good as the old hot tanks but that's the world we're livin' in...
I bought hundreds of gallons of mineral spirits for 30c a gallon, last I bought was about 80 bucks for 5 gal...
I never could stand diesel to wash parts, just greasy and slimy.
