Do not use Acetone on Plastic. It will depend on the type of plastic, but I would rather be cautious if I were you.

As far as the GooGone is concerned- it will leave minor scratches on plastic along with a white surface residue that is produced. The white residue will not just wipe off.

Have you tried using distilled water and a mild detergent?

Test any solvent on a inconspicuous part of trim before you apply it all over.

 

The only thing I've tried is the various glass cleaners I had handy... none seemed to do the trick.

 

Try Xenit from Stoner. It's orange based and shouldn't be too harmful it you spray it on the plastic (as long as you wipe it up pretty fast).

 

tried simple green?

 

Goo Gone

 

Have you managed to get it off?

If so, what did you use?

 

WSB - try "JerseyGirl's Famous Window Cleaning Solution"!

Mix about 2 cups hot water with 1/4 cup each of white vinegar & ammonia. Use two rags (or paper towels) - one to wipe the solution on the windscreen and then the other to wipe it off. This will work well on windows, windshields, etc. No streaks!

Good luck w/ it!

 

Will the ammonia damage plastic (i.e. the rear view mirror)?

 

if the above doesnt work... or if you want another idea:
try a glass polish such as autoglym:

btw, to prevent this in the future, spray your sunblock product on a rag away from the car and then rub it onto the area that you are protecting (dont spray it in the car).

 

Strike one! Didn't work.
