Engine "Hot tank" question

It takes something bigger than a 55 gallon drum too, but you can reclaim the stuff off the top and slowly dispose to sanitary sewer (it will degrease the municipal sewer nicely, about a quart every three days, the solution for pollution is dilution) and mix the sludge with bentonite clay and bag it up in your trash for the landfill. You didn’t hear it from me, though, lolol!

A 55 gallon drum will hold a small block and a slant, not at the same time, of course. I don't know about a big block. Never tried one. As far as disposing of anything, I haven't made one out here yet. I had one when we lived in the Macon city limits. When I changed it out, I neutralized it with vinegar. Anything acidic will work. Hydrochloric acid is usually used for its strength but vinegar is much more readily available.

My plan was when we moved out here in '02, to get some 1/4" plate and make a nice hot tank......among other things. But life happened and I never did it. I may yet, though, as a hot tank can come in handy for lots of cleaning. As seldom as it would be used the solution would probably stay strong a long time.
