a friend suggested acetone. I have acetone based nail polish remover. it worked! and it didn't even stain the terra cotta. so maybe I can just leave this here as a tip for anyone else who may have this issue.
so I bought a terra cotta pot and saucer to make an item I've had on Pinterest for a while now, and unfortunately the company that makes them felt it was necessary to use the stickiest stickers known to man for their barcode stickers. I tried peeling it off, but we all know how that went. so I tried Goo Gone. BIG. MISTAKE.
it did allow me to remove the sticker, BUT, not only did it begin to soak into the saucer, it left behind sticker gunk. now I'm afraid that my paint won't stick plus I don't want there to be visible sticker gunk lumps. any suggestions on how to get that stuff off?
and if you're wondering, the bottom of the pot won't be visible, so I'm not worried about that sticker. however, the bottom of the saucer WILL be visible. makes you wonder what I'm making doesn't it...
