As an aside, I've found that citrus-based degreaser works quite well for
removing the toner from toner-transfer PCBs. I think that the stuff I use
came from a bike shop, but probably any place that sells automotive supplies
would have it also. It works much better than the watered-down acetone that
is sold as nail-polish remover in grocery stores, and the fumes are less
nasty too.

I suppose full-strength acetone works well, but I'd rather not use that
stuff.

Dan, this may present a setback in your negotiations with your wife
regarding your hobby. :-/
