Default How do I remove that suction cup circle from the windshield?

Although it’s normal to have these suction cup marks left from the factory window installation I can’t get rid of it. I have cleaned the area countless times but that has failed to remove them.

Any tips of how to remove it?

Isopropyl alcohol on a microfiber towel, and a little elbow grease. A higher percentage concentration bottle is a good thing to have around for such occasions.

Please let us know if the Isopropyl alcohol on a microfiber towel does the job. Thanks.

I would be trying Griot's Surface Prep Pad on a random orbital, lubricated with speed shine. The pad is primarily meant as a substitute for the clay bar on paint, but Griot's recommends that it be "broken in" first on glass, Having done that, I noticed how nice, clean, and smooth it makes the glass. It tends to pull everything off the glass that is not supposed to be there. If that did not work, some fine polish. Having read the posts above, I would probably try the alcohol first.

Try Acetone it's a strong alcohol. No lacquer thinners ever!

No, acetone is a ketone, not an alcohol. It is quite volatile (evaporates and fills the air easily), and will irritate eyes, nose, throat, lungs. A fair amount of exposure one day back in the lab in my youth left me pretty whacked, and I somehow ended up hours later sitting on my bed at home, and no idea how I got there. It will also adsorb right through your skin. And is crazy flammable. That being said, it works as a solvent via a different mechanism from alcohol, and can clean stuff that other solvents can't touch. Just be careful with it. Lots of fresh air, wear gloves, and nothing flammable nearby. One can get pint cans of it at places like Loews, Home Depot, etc.

I'd probably put a lot of paper down under where you were going to work, to keep it off everything else in the car. I'm not sure what it would do to leather or plastic, someone else will have to find out.

Both alcohol and acetone are in the Isopropanol family. Its not that volatile, if it was, it would not be the main ingredient in nail polish removal .
