      Is it ok to use Bon Ami or Bar Keepers Friend on a MKVI windshield? Is there some type of coating that might be damaged by those products? I have this one spot that has some kind of film that refuses to come clean. Any suggestions? Thanks

      That seems more abrasive than Bar Keepers Friend or Bon Ami.

      We use #00 steel wool all the time on glass w/o issue. I would reach for that over an untested chemical first. You have a chance to etch or stain glass with chemicals.

      Though if I were in an experimental mood I might try some soft scrub or comet. I've never used what you're asking about but if they are similar I would try an inconspicuous spot first like a side window, out of the field of view. Be sure to not let it dry and rinse thoroughly.

      Interesting information on Bon Ami's website http://www.bonami.com/index.php/prod...wder_cleanser/

      Ingredients:
      Limestone ~ Calcium carbonate
      Feldspar
      Biodegradable cleaning agents ~ Alkyl polyglucoside
      Soda ash ~ Sodium carbonate
      Baking soda ~ Sodium bicarbonate

      I have used Bon Ami for cleaning automotive windshields ever since BMW recommended your product in response to customer complaints about road grime making it hard to see out in the rain. We use a vinegar and water solution to neutralize acid rain spots then follow up with Bon Ami and the glass looks like new!

      So I guess if BMW recommended it, it must be ok.

      And then on the Bar Keepers Friend site…
      http://www.barkeepersfriend.com/car-care

      “This worked for me, Bar Keepers Friend. I found it by the Comet® at the local Walmart. I mix it with water in a bowl and made a paste out of it. I used a towel and rub it on the wet windshield in a waxing motion. I later sprayed it off and bada bing, no spots ! Like others, I have tried vinegar, CLR® , Scotch Brite™, etc.. This took me about 20 minutes using no more effort than normal waxing.”
      I guess I'll have to try it out.

      Bon Ami is extremely gentle, fine for glass. Personally, I love this stuff:

      If you want a designated windshield product that is pretty good at cleaning spots off of windshields, try some Duragloss #755 Nu-Glass.



      I have used Bon Ami on a MKIV windshield before with good success, but not a MKVI windshield.

      A clay bar does wonders, followed by RainX.
