I just acquired a vintage stewardess bag. There were some strips of duct tape stuck on the interior on the inside zip pocket suede. I wondered, why? It pulled off easily, being who knows how many decades old. What I found underneath was disgusting!! There was gum (I think it was gum) and the foil wrappings on the gum all misshapen and melted and stuck in varying size globs hard as rock on the suede. So, rather than clean a mess in their bag, they covered it up with duct tape? Crazy. Anyway. I soaked the bag and then scrubbed the area with a toothbrush got really ALL the gum off it, but there remains speckles of foil and adhesive residue stuck on the suede. My idea is to pick at the pieces of foil with a tweezer. Any best ideas on how to remove duct tape residue from suede? I should have taken a picture of the original shocking mess. However, here's what it looks like now.
