"Mineral spirits," common paint thinner, is also known as Stoddard Solvent.
It's moderately active, somewhat less so than gasoline. A Coleman employee
once told me that this is what they used to sell as "white gasoline," but I
don't know that for a fact.

I hadn't heard it called Stoddard Solvent before -- my dad used to
just call it "solvent", and when I went looking for it nobody knew
what I was talking about!

I had heard Coleman white gas was indeed gasoline, but without
additives (especially no lead).
