Welcome to the new look VWWatercooled

After much work and little sleep there is a new version of the forums running on more powerful and recent hardware as well as an upgraded software platform.

Things are mostly the same, but some things are a little different. We will be learning together, so please post questions (and answers if you've worked things out) in the help thread.

The new forum software is an upgraded version of what came before, it's mostly the same but also a little different. Hopefully easier to use and more stable than before. We are learning together here, so please be patient. If you have questions, please post them here. If you have worked something out and can provide an answer,

  • Removing white residue from black bumper plastic

    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

    It really looks like polish on the bumper.

      Quite probably what it is. I've suggested some all purpose cleaner and a soft tooth brush to start with

          I've had good results with Mothers Naturally Black Trim & Plastic Restorer
          Used to be called Back to Black.

          If it is just wax then maybe try alcohol wipes.

            Apparently my old man has already trued Back to Black, but with no luck. I still think it just needs more elbow grease. He's going to try a bunch of things this weekend. The alcohol wipes are not a bad idea either. Thanks!
