Yet another amazing bargain from play.com in the summer sale! This repair kit repairs damaged audio CDs, game Discs, CD-ROMs, CD-Rs, CD-RWs and DVDs, and it contains enough fluid to repair up to 40 discs. I've heard of this stuff, but I have not yet had the chance to try it. If refers to itself as liquid sandpaper...! It seems to get good reviews, so might be worth a few quid to help keep your discs in good order.
