Homebrew PCBs

Hello Sir Dennis,

Yes, I use a little WD-40 to get the rest of the
residue off the board.

I will go ahead today, and get a brand new sheet of
double-sided PCB at Radio Shack, and then make a
design from one of my projects at my website.

I will let you know how the etchant worked on the
board, since I am not sure all of the residue was
taken off.

                             ...your friend, Patrick

P.S. But the board sure came out great. I was amazed!
