We have a coin counter that I need to repair and I'm thinking using fiberglass to mend it. First I need to remove all the adhesive from the duct tape that my wife used to patch it. The part I'm repairing is cheap thin plastic without any identifying markings. I tried lacquer thinner and it didn't like that, it melted and got shiny. any suggestions what I should use?

Alcohol or Goo-Gone.

In the off chance that one won't work, the other usually will.

I've never used the 'Goof-Off' stuff.

Like others, I've had pretty good success with liberal amounts of WD-40. But like they also commented, you have to thoroughly clean it off with warm, soapy water if you plan to bond anything to it, or paint it. And you'll likely have to clean it several times to be sure all of it is clear of the surface.

Think... in body-shop, and about to go in the paint booth, degree of clean. Most body shops don't even allow a can of WD-40 or Armor-All type sprays even in the same building as the body shop.

goof off is better suited at removing marker marks and other stains, than it is at removing tape or sticker goo. The Goo-Gone works better at removing the adhesive goo than goof off, however the Goo-Gone also leaves an oily residue. WD40 isn't really an oil, actually it can be used to remove oil and dirt from surfaces. Whether you use WD40 or Goo gone, be sure to clean the surface real well afterwards as others have said.

You could probably make some progress with the guy from the other thread trying to get rid of the Coleman fuel. :)

I would be curious what the vinyl sign shop uses. I use 3m adhesive remover and it works well

I've worked for several sign shops. Everywhere I worked used xylol.

Without knowing the exact type of plastic you've got, I'd use anything sparingly. I work in a graphic design department and we use Bestine for almost all adhesive removals. It's solvent based so it doesn't leave a residue and in 25 years of using it I haven't noticed it attacking plastics. I HAVE seen fiberglass resin attack some plastics (probably from the heat during curing) so be careful with that stuff too.

if it's still gooey then WD-40 should work fine.

Naptha or good old lighter fluid. Won't hurt plastic and no need to clean it again after removing the gunk like have to with WD-40...

We had a bunch of duct tape residue on the exterior of an old car. The tape was used to hold plastic over a broken window for several years. The residue was rock hard from being in the sun, and nothing seemed to touch it. Finally tried methyl hydrate, and it removed it no problem. Didn't hurt the paint at all. It's cheap, so maybe try some on a small piece and see what happens.

You have a resourceful wife anyway. That's good.


If duct tape doesn't work, you're not using enough duct tape.

WD-40, ATF, baby oil, mineral oil, any oil... The adhesive is rubber based, so any oil should work.

Goo Gone is my usual choice, but for delicate materials, I use Spray 'n Wash. Besides removing stains from fabrics, it removes sticky adhesives. Not as fast as Goo Gone, but it will do the job.

Use a fresh piece of duct tape to pull it off, microfiber cloth and water will remove the rest of it

The results are in...Goof off got the adhesive off, but melted the plastic. Goo gone removed the adhesive and left a slightly oily residue. I washed it with dish soap several times and now I' ready to fiberglass this thing back together. The Goo Gone has a citric acid and petroleum distillates base.
