What solvent should I use to remove tape from an old newspaper?
Q. Dear Donia,
A. Dear Karl,
It is almost impossible for me to tell you what solvent you would need to use to remove the tape. If the paper has gone translucent from the tape, the adhesive has cross-linked. This will make it difficult to remove with a single solvent. When conservators remove tape, there is a lot of experience, training, testing, and experimentation involved under very safe and controlled environments. I would not recommend trying to remove the tape yourself.
Are you sure that this is a unique newspaper photo? If so, it is probably best to contact a professional conservator as this is not something that is easily done by the amateur. You should be able to find someone at the Arizona State Museum or they can refer you to someone.
