I'm new to this forum, and thought to ask something that's been bugging me for years. Does anybody have experience with either commercial or home-made (audio) disc cleaners and scratch repair agents that they are happy with? An internet search has turned up a few seemingly good products (303 Sonic Blast, CD Doctor "GP" and "Protect", Disc Doctor Miracle Cleaner, Liquid Fusion) , but all seem to toot their own horn, with no consumer reviews. An e-mail to CD Doctor indicated they don't sell a commercial cleaner anymore, because a mild hand soap with distilled water seems to do just fine. Most of my discs are in perfect to excellent shape, so a regular-use cleaner (and protectant, if possible) would be ideal. Some are scratched and spurious noises are now coming from them, so a "repair" agent would also be beneficial. Experiences anyone?
