This is my process for cleaning Technics 1200 platters, not a definitive method, still developing ways to get a full mirror finish . Open to suggestions. - Recommended only for extremely oxidised and pitted platters - i recommend trying Autosol first (as directed on the can ) on the upper, outer and under edge of the platter before taking to it with a high speed tool, its amazing what that stuff can do, best to try and preserve the OM factory finish.
