Many years ago when I first started buying records I was persuaded to put sellotape( sticky transparent tape) over the open edges of the album covers to protect them against wear. A bad idea. Now the sellotape is old , yellow or brown and starting to peel off. But it leaves a sticky brown residue. I still cherish the looks/quality of my vinyl and would like to know how to remove the tape and residue without damaging the covers. Any ideas????
