GooGone is a liquid that helps remove adhesive residues. I’ve been using it for years to clean off the adhesive residue left from stickers, labels, tape, etc.
Let’s say you just bought a picture frame and removed the label from the glass. In order to remove that irritating, gummy adhesive residue left by the label, you just rub a bit of GooGone over it with a cloth and the goo is gone! No need to use a razor blade, acetone or other nasty solutions.
Not much of an odor, and an 8oz. bottle lasts for years since you use just a small dab each time!
