Naptha won't help the flammabilty/explosive danger.

Thanks for looking at the problem from a scientific standpoint.

The main issue is that gasoline is a *fantastic* readily available and cheap
(relatively) solvent for eliminating the goop under the labels (after the
label is removed by soaking in water); but gasoline (a) stinks, and (b) is
flammable.

So all we're trying to do is reduce those two deleterious qualities:
a. Lower the stink (or mask it with a better stink perhaps)
b. Lower the flammability issue (probably by lowering the quantity)

Looking at naphtha as the diluent and gasoline as the solvent, and assuming
something around a 1:10 ratio of diluent to solvent, the first thing I find
is that naphtha is, like gasoline, not a single chemical in and of itself.

Looking up whether naphtha is a good diluent for gasoline, people do it:

But the results were too complex for me to glean the gist of the results in
a single skim, so I'll move on to the next suggestion for the moment.

Butane is even worse.
I don't see butane readily available either.
It might be (e.g., lighter refills), but it seems too flammable for me to
consider as the diluent.

Methanol is corrosive, VERY flammable and poisonous (absorbs
through the skin too)

The problem, I think, with *any* alcohol, is that they're gonna dilute it
with water, and water isn't what we want to mix with the gasoline, so,
unless we can find reagent grade alcohols, I think alcohol that we do find
will have water in it.

Dichloromethane may be an alternative but it has serious health risks
as well

Is that a common household chemical?
