I've been using GooGone for 40 or 50 years (has it been around that long?). Just three days ago, I used it on the sleeve of my good blouse. There was a spot of what seemed to be tar. I have no idea where it came from, but it was a really black spot. I put just a few drops of GooGone on it and in about 30 seconds was able to scratch the tar off completely. Then I put a few drops of soap on it and scrubbed a little; rinsed that off and put it in the wash. (The directions on the bottle say to wash it out before putting in the wash machine.) Blouse is as good as new.
