What I do with used records is to clean them with my Nitty Gritty, then treat them with Gruv Glide and place them in a new poly lined sleeve. I wipe the jacket with a slightly dampened cloth and, after drying, store in a "japanese" resealable cover. I put a "GG" on the cover with a magic marker. This way I know an album is clean and the need to reclean is minimized by using a new sleeve and cover. The cover also protects the jacket from deterioration. I usually do the same with new vinyl.
Is it necessary to clean every record?
I'm constantly buying used records, some of which are in excellent to mint condition. I put them in an ever growing stack of "to be cleaned" records, some of which are now several years old, because I have a rule not to play records that haven't been through the VPI machine. Is it really necessary to clean the ones that appear as if they've never been played? I listen to a Planar 25, Classe integrated, and Spica TC-60's. I'd appreciate your thoughts.
