Hi all,
My dad has asked me, and I don't know, so I'm asking here. He washed his new car (not a VW) a few weeks ago and whilst using Bowden's auto body cleanser, it left a white residue on (or has damaged) the black plastic bumpers of his car:

He has tried some products that are supposed to restore plastics and vinyl but they haven't worked. He can't get it off and I have no idea what to do here. Any suggestions?
Any help would be appreciated. Next step is to pay a pro.
Thanks!
- Matt
