Who, me? A couple of BTW's: Most of what I talked about concerns records from the early 70's, 60's and 50's (thin-jacketed 80's sleeves, for instance, tend to be colorfast and glossy all over; 40's jackets nowhere). For tape and label adhesive residue, forget about all of above, including alcohol, which will usually just move the adhesive around into a larger blotch if it does anything. If you are determined and willing to risk it, only WD-40 or a dedicated adhesive remover (I have a product called B'laster E-Z Take-Away, but there are others) stand a chance of disolving old glue, but be very conservative and only blot it up, don't rub. And if it looks like it ossified forty years ago, give up before you start. For pencil (and some dirt, too), a white draftsman's eraser can be of help sometimes; for ballpoint and magic marker, not. Good luck!
