I think if will depend on adhesive. I suspect it isn't water soluble or you would have already soaked it off.

There are products that remove gummy adhesive by disolving it in a turpentine base, like Goof Off. You might try that but I wouldn't leave it on fabric for long. If you rub it off with an adhesive remover, throw it in the wash and wash it good.

Sorry I'm not much help.

Some of the labels peeled right off. :-) One that didn't found its way into the wash, and a gummy adhesive was stuck to the fabric. I'm glad it didn't get all over the rest of that load! We will try Goof Off next on the firmly stuck labels.

I've used a hair dryer to remove labels. Heat softens many adhesives and labels peel off easily.

Also try sticking it in the freezer then pulling it off.

To get price tags off books, I use isopropyl alcohol (rubbing alcohol) on a paper towel to rub the gooey stuff off without damaging the book. Wondering if that would work on fabric?
