Homebrew PCBs

I've soldered right through the toner on pads on th boards. The problem 
with acetone is the toner melts and spreads around and you get a messy 
looking board.

  All in all I've found it not really worth it, just clean the whole board 
right before you solder. Oxidation has not been a problem. If you really 
care about long term, use a conformal coating when the boards been completed.
