How do I remove hot glue from a piece of vintage clothing?
The first thing I would do is put the piece of clothing in the freezer. I have found, from living in Alaska, that hot glue pops off of items when it freezes. So if there is a lump of glue that might remove it. If there seems to be glue in the fibers try to heat it to remove it. Take a piece of clean cotton and place the glue spot face down on it. Press a hot iron on the area (make sure the clothing is safe to iron at a high heat), pressing for 10-20 seconds. Peel it away from the cotton. Move the cotton over to a clean spot. Repeat until the glue has been absorbed into the cotton.
Best of luck,
