I have been advised that a good solution for parts cleaning is 1/2 mineral

Do water and mineral spirits even mix? I'd look at what needs to be cleaned,
and what needs to be cleaned off it. I once read about some guy who washed
his lawnmower (with all that grass clipping crud) in Tide, and all the
paint fell off.

Would a 5 gallon container be sufficient??

I think that would depend on the size of your part.
