What is the most effect way of removing hardened duct tape adhesive from car paint and glass without causing damage? Answered

My car window regulator broke so I had to hold up my window with thick black duct tape. It baked in the sun and the adhesive hardened on the car paint and glass. What is the most effective and safe manner in which to remove this hardened duct tape adhesive without damaging the car paint or window?

Eith WD40, Goo Gone or olive oil will work. Use a microfibre cloth.

I tried my partner's suggestion: Bicarbonate of soda + citic acid. Ratio of 1:1 of each powder mixed in a little water, soaked into a cloth. It took around 15 minutes from 8 places, requiring firm, focussed scrubbing. It felt great seeing the marks finally come off! The residues had been left mostly for about 2 years facing midday sun (UK - so not as hot as many places!).

Any kind of citric acid is terrible for auto body paint.

WD-40 and goo gone can remove tape residue and your paint's overcoat/finish. Keep researching to do it unhillbilly like.

You can use a regular razor blade for the window. Not sure about the body.

this morning I was trying to clean off baked on masking tape that was on our trailer, and I read Kitskid's suggestion. I remembered that WD 40 has 101 uses so I gave it a try, letting sit on the tape for a few minutes... It Works, it really works with so little effort...thanks Kitskid

Goo Gone! from Home Depot! peal the tape off, spray the solution and wipe away, you may need to do it a few times to get all the glue off!

Hope this helps!

I've used a hair dryer to soften the tape and adhesive.

I letter vehicles for a living...we use an "industrial" strength version of Goo Gone which you can get pretty much anywhere. Just squirt some on and let it sit for 5-10 minutes and wipe in a small circular motion. Repeat if necessary then clean with windex. It won't damage the paint. Application would be a lot easier if it were in a spray bottle so it doesn't just drip off the car.

Thank you for your replies. I will look into the WD40. My biggest concern is avoiding any kind of damage. Especially avoiding paint damage. I know that the solvents used to remove such residues can be rather harsh. I am looking for the safest solution. Hopefully someone on here has had to perform this same task and has a tried and tested solution. Thank you all nonetheless.

Goof off or some such from the cleaning aisle- test on very small patch of paint before going crazy with it. WD-40 will probably work also

Try spraying a little WD40 on it and let it sit for about 5 minutes. Wipe with a cloth and see what happens. I think the WD40 will hekp.
