So I'm sitting here listening to my Led Zeppelin II LP and I'm hearing a lot of clicks and clacks. I know, the album is pretty scratched and no matter how much I clean it, I'm still going to hear them. However, I somehow feel that by cleaning the record a little bit (if that's possible) will enhance my listening experience. I'm probably wrong, but just for the hell of it, can somebody tell me how to clean records properly, without scratching/damaging them more? Thanks.
