I have a DFI NF4 board with a 1900xt due tomorow, which means that I will need to change my cpu etc over from my current board onto this new one. When they are removed the contact surface will no doubt need a good clean for both items. I've tried getting hold of some isopropyl alcohol but I cant find a chemist that sells it, I'm just wondering what, if any, cleaning solvents I could use instead that you might find around the house. I have nail varnish remover (not mine) and the standard cleaning things that I wouldnt want to go near my pc with. Any suggestions as to what I could use, just wondering if there is something I havent thought of.
