Homebrew PCBs

I would not base an assessment of toluene based on trying acetone. I
have seen (and used) acetone as the suggested method to quickly remove
toner from a board after etching. Your toner may look fuzzy because
the acetone partly dissolved it.

Hmmm... gonna have to Google. What is toluene and where would I find
it? Maybe it is supposed to dissolve the coating on the inkjet paper
while not dissolving the toner?
