Removing ancient tape

[David A. Goldfarb]

Naphtha shouldn't leave any residue. It evaporates very quickly. I actually picked that up from a vintage guitar shop in Manhattan.

Lighter fluid is mostly naphtha, but one never knows what else might be in it.

I bought a 32 ounce can of naphtha at a local hardware store from their paint department. It cost eight bucks but it'll last me a long time.
