ok so a while ago I used to put patches on my Jansport backpack using hot glue. I took them off, and now my backpack looks fugly, with translucent white spots and rings on the face of my backpack. Any tips on how to remove hot glue from backpacks? I don't know what material it is made out of, although it looks like sewn nylon??
thanks for any help.
