Re: [BKARTS] Conservation question regarding scotch tape

[Bruce Levy <levybooks@xxxxxxxxx>]

It's possible that naptha, or any solvent aqueous or non-aqueous, could cause tide lines due to degradation products in the leather.  If the leather is a very dark color (like black) it might not make a difference, other than possible "blooming" which can probably be removed (like with dressing or saliva).  If the tape adhesive has cross-linked (become hard and/or brittle) you might be able to just lift the carrier layer dry.  In that case you can reduce the adhesive mechanically with a blade and a subtle touch.
