I got this old rig that looks like a flame thrower.

I hook my garden hose to it, it has a float in it and a big coil and it burns diesel fuel like a jet through these coils and blasts out enough hot steam and pressure to clean an fifthly engine block in about 10 minutes. I fear one day it will blow up.

Then my old old hot tank that has two hot water elements in it, 4x8, foam insulated and I still have two bagged pallets of this stuff that says "Caustic Soda" and it will eat bearing and AL parts out of anything in about 2 days.

Id say this is a killer setup for me, I hardly have a use for my lessor more common parts washer, I never liked those, the fluid would sting my hands.
