As kind of a practice run I etched a simple 555 circuit into a board using the laser printer method. Now I have a nicely etched board, but using the "Resist Ink Solvent" from the radioshack etching kit (I think it's just rubbing alcohol) I am having a very difficult time getting the toner off. I've spent several minutes scrubbing it with a toothbrush submerged and out of the solvent, but there's still lots of toner left. What's the best way to remove toner from the board?

edit: Never mind, I found the scouring pad in the RS kit, which did a much better job of getting the toner off, though it did take a bit of copper with it but nothing a little solder can't fix.

 

You could try something a little stronger, like acetone (nail polish remover). That removes most inks quite well.
