I was watching this program on Sky Arts the other night about a guy who collects radio broadcast transcription discs from the 30's onwards, his collection are all on 'soft wax' in other words, acetates, anyway he showed a few examples, all were covered in mould, so he put one on the deck then explained that he used a secret cleaner for acetates only, sprayed this stuff on and played it, and it cleaned it up nicely while playing. The secret cleaner was actually Windowlene. So it looks like that is a safe cleaner for acetates, but he said it couldn't be used on ordinary vinyl.
Nothing earth shattering here but I just found it interesting thats all, anyone used windowlene for cleaning records?
