I'm thinking nail polish remover or some other solvent but I'm not sure what will also take off the solder mask at the same time. Good silkscreen is very tough, we had some boards with component outlines printed on the pads and we couldn't remove it even with solder iron. What I did with some success is to use very fine wet sandpaper (I used 1000 grain/mm2) and carefully sand it off. The soldermask is much thicker and it won't wear off but the white paint will. You also get a cool looking matte PCB. Djula -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
