From my time in radio I remembered the conditioner we used on rubber pinch rollers when they started slipping on tape (yes, that long ago). I had a old bottle that I have used from time-to-time to fix print rollers. Unfortunately I've lost track of the bottle, but I think it was CaiKleen RBR... here's a link to buy a small bottle. Price is about $13 for 25ml (and that should last a long while).

Radio stations don't use a lot of tape anymore, but it's good for printer roller AND for that old 8-track player! Use a cotton-tipped applicator, and carefully, it's pretty sticky stuff.
