The missus kindly bought me a phone holder which she stuck to the dash for me too. It's left this ring where presumably the adhesive has ripped of the top coating. Any ideas how I can remedy this? I've tried using toothpaste as a mild abrasive but that didn't work.
If I were going to try anything it would be trichloroethylene AKA dry cleaning fluid/brake cleaner. I'd try a tiny bit on an inconspicuous part of the dash first but I can't see it harming it. You may need to do the whole upper dash however.
Nail polish remover initially use a cotton but on a small section. Then apply google interior restorer like Meguiars #39
Finally got around to trying the nail polish remover and it's pretty much worked. I can still see a very vague pattern there but only when the sun hits it in the right way. I'm going to give it another few goes to see if it can totally remove it.
