I just had my first experience yesterday. I used the HP laser printer at work to make the photocopy art work. I used a cheap $19 iron from a local hardware to transfer. I used 1 part Muriatic acid to 2 parts Peroxide to etch.
I put the boards in a smaller portion (one cup to two cups)of this concoction and agitated them lightly with 2 of those disposable metal handled glue brushes. It worked PERFECT! Every so often I switched from board to board and rubbed lightly with the brushes (kind of held the board down with one and spun the other brush lightly). Maybe 5 minutes later, I was down to clear boards. I rinsed them, dried them and wiped them clean with acetone. BINGO ..... 5 perfect boards. I was so happy.
I basically used the info at
http://www.fullnet.com/~tomg/gooteepc.htm and had great results. Ken has lots of experience and there is alot of info there for the newbie. (like me)
