What is the best way to clean Vinyl?
@jjbeason14,  Vacuum RCMs are mostly about convenience - they suck the fluid from the surface.  The chemistry used, the brush used, and your technique determine how clean the record will be.  There are very high $$$$ vacuum-RCM that have automate...

Many reasons, just a few: IV.10 Records that have been fully cleaned can still sound – for want of a better term – bad; clicks, pops, hiss, and distortion. There are any number of reasons such as following, but no amount of cleaning is going to f...
