Need solvent, blast media & pressure regulator

Yeah, not looking for any water based cleaners. I've read a lot of people using odorless mineral spirits in theirs. Disposal won't be a problem, we'll just pour it on the burn pile. I think I'm gonna need at least 10 gallons.

Not really recommended. Pouring it on a burn pile still has some of it soaking into the ground. If you have a well, you will end up drinking it. If you don't, somebody else will.
