Removing decals from plastic ?

Soak the decal in hot water to remove most of it. Dry it and put peanut butter over the rest of the adhesive. Let it sit and wipe it off.

See if the heat from a hair dryer will loosen the glue. Be careful about applying things like nail polish remove as it might discolor the plastic. I hate those stickers.

Vegetable oil and a plastic scraper will loosen the adhesive and help you remove it. Many times if I can get an edge with my scraper, it will come off and then I rub a drop of oil to remove any residue. Then soapy water to clean.

I would use a hair dryer and gently take them off, the heat will loosen the glue and they should come right off.

Perhaps one of these ideas will help you out!

I wonder if Goo Gone or WD-40 would work. You’d have to test a small unseen spot first to see if the bowl can handle it.

I would stay away from a scraper, might scratch the plastic. Maybe try the usual stuff: acetone, thinners, turpentine and benzine. I don't think those are sticker decals but rather printed onto the plastic, so treat it as if it was print that you were trying to remove from a plastic bottle.

I am a Goo Gone girl myself. I have kept a bottle of this stuff to get price tags and decals off things for years! I buy cheap cotton swabs from the Dollar Tree as my “applicator”. It has never failed me.

Not certain this would be the same, but I remove plastic and paper labels from bottles and jars by putting extra hot water inside for a minute. It softens up the glue and you can pull it off easier after pulling it up a bit with paring knife.

Soak in soapy water until it comes off.
