What about when the object is aluminum and you don't want to use a strong
basic? (I found a preme-o Devilbiss spray gun at the dump that I need to

Watch material firms sell an ammoniated (Stoddard)solvent based cleaner. It
has some sort of blue soap in it as well. Warning, it's pricey! In the 1970s
it was $30.00 CDN per gallon.
