Has anyone dealt with this kind of cleanup before?
What are my best
options for solvents to get rid of what's left of the rubber without
damaging the tapes too much more?
Chris, I'm pretty sure you can clean (very carefully with a picker and a
swab) these tapes with "Benzina". I don't know how it is called in English.
Maybe "white spirits" or something like that. It dissolves rubber (even very
old rubber) and cleans the paper without attacking the paper fibers. But be
VERY careful. It is toxic.

PS: Now that is something I never tried to make - a paper reader. Must
be a fun weekend project :oD
