just my secret magic ingredients and process. Everyone has their own...
PM me and I'll take your records, clean them, and send them back. This is not a general invitation to anybody (I'm not running a cleaning business), just willing to show what good a cleaning can do. Make a recording of them before you send them to me, so you can rerecord after and compare. There are some things that cleaning won't fix, like heat damage (usually causes a "swoosh" sound), scratches, etc. I also don't polish records (totally dishonest practice) or shine them up with armor all or anything like that so you don't have to worry about that.
