Hello Listers, Please excuse cross-postings. A vegetable tanned leather doctor’s bag (1775- shoulder bag style) needs treatment for mold infestation. The front flap has lost flexibility, is brittle and curled (see attached photo). I would appreciate your suggestions regarding the eradication of mold spores that may remain after mechanical removal is complete. In addition, is there a safe way to soften the front flap to return its characteristic flexibility? Can a PEG 400 solution be safely utilized? Other suggestions?
