How to remove old bike license sticker?

It's an old city license. The adhesive appears to be similar to what I've seen on automobile license tabs. It's pretty large, - about 2.5 inches tall and fitting 3/4 of the way around the seat tube.

I'd like to remove it without trashing the paint which is in pretty good condition.

There's also a sticker from the bike shop it was purchased from. It's a bit ragged but on the other hand it's an old and respected bike shop and being a vintage 70's bike, I'm tempted to leave that one.

Any ideas?

I have successfully removed old licenses using 'blister pack' plastic. Flexible enough to wrap around the tubing, yet hard enough to safely scrape away the sticker, and it doesn't scratch the paint.

Try warming it with a hair dryer, and see if you can lift a corner with a fingernail.

Rubbing alcohol, isopropyl, might work to remove the leftover adhesive, or try paint thinner. Neither one should affect the paint.

Concur, hair dryer is the only way on these types of metallic stickers. Get it pliable enough to pull off in one piece. Use naptha to wipe up any residue.

I removed one from my Paramount by warming it and gently peeling. A little paint thinner (mineral spirits) or WD-40 can soften the glue as you go.

I left the bike dealer sticker, too. I like those things now, though I wouldn't have back when the bike was new.

Just curious. Would you leave it on because it's part of the bike's history, or because pulling it off might damage the finish?

History. I like my Hawaii bike shop sticker. How did it get to Pennsylvania Amish country?

You can use Goo-Gone or Goof Off to soften the adhesive. Just be sure there are no decals underneath.

There is a product called "Un-Do" that you should find in scrapbook or craft stores. It comes in a bottle with an applicator that acts as a putty knife/funnel to direct the solvent under the edge of the decal. Using some heat helps, too. I use my wife's small embossing heat gun because it gets hotter than a hair dryer. You can get one at the craft store for about $15.

I agree about the history of the license stickers, but some are huge and hideous, or cover up some important manufacturer decal.

I wouldn't use a heat gun with the chemical products. Most contain flammable solvents.

I should have been more clear: Use the heat gun to warm it up first, then use the solvent if necessary. Usually, the crafter's heat gun is enough to get the decal off with out solvents.

Note, the crafter's heat gun is not the same as the ones that are used to peel paint. It is more like a small hair dryer but with a low speed fan.

Years ago I cleaned my bike with GUNK, it really made the bike shine, but after a few applications, I noticed all the decals were peeling off. I don't use GUNK to clean bikes any more, but it might work for your decal
