I've always been troubled by not knowing how to remove glue residue.
The worst is glue left after peeling off labels. I've used hair dryer heat and water soak plus scrub to get by. Now I'm confronted with residue left from size labels on a pair of thongs bought from a discount store. I'm sure if I wear these thongs several times the patch will show, and the sticky feeling is most unpleasant, too.
Any way to "dissolve" the glue? Without leaving a mark on the soft material which does not look like leather and is rather absorbent similar to cardboard though I'm sure it's not.
