The Spin-Clean® Record Washer Mark II's real effectiveness comes from its ability to impeccably clean both sides of any record simultaneously without using your turntable as part of the process. The “heavy lifting” is accomplished through Spin-Clean® Record Washer MKII's unique washer fluid. This special formula encapsulates the dirt that comes off the record from deep within the record grooves and sinks it to the bottom of the washer basin, so it is not re-deposited back on to your valuable LPs and 45s.
