Used it on the outside black wheel well plastic trim. It's a Jeep. Now it gets white really fast. Thoughts?

i say go to walmart in the automotive paint part and there should be a glue adheisve and wax remover that 3m makes i used that to get rid of most of my armor all crap.

Try some vinigar. I've never used it on armorall but it works on removing hard water marks!

You could also simply scrub it gently with a strong car wash solution and a gentle brush.

Personally, I'd use Mothers Back-to-Black, since it sounds like you need a restorative trim dressing anyway.

Rubbing alcohol? As long as you don't get it on the paint, you should be fine. If you do get it on the paint, just wax it again.
