    Messed Up Rear Window...

    I inadvertently sprayed 409 multi purpose cleaner on the inside of the rear window while cleaning the headrests; didn`t realize it for several days. Now it has spots that I can`t get off. It seems the cleaner has penetrated into a coating. I tried the same 409 to no good, and several others including all the glass cleaners I have. The glass has defrost wires on the surface so I have a concern that using steel wool will ruin it. I will be greatly appreciative to receive your thoughts on how to get the glass clean again. Thank you.

    Wow. I know they tell you to be very careful with Optimum Power Clean, especially at full strength, about letting it dry on glass because it will etch. Sounds like 409 may do the same thing. Sounds like the only option maybe to carefully use a glass polish by hand between the defroster lines...good luck.

    You may want to try a liquid carnauba wax. They have light cleaning abilities. You can use it on the glass and scrub it a little bit with the wax on an applicator pad, shouldn`t harm the defroster lines if you are careful either. If that doesn`t work, then what Setec said. Have to be careful with the defroster lines and a glass polish because it is abrasive--may be worth masking off.

    I`d be afraid pulling the masking tape off could pull up the defroster line...but that all depends on the tape, how long it`s been on there, and how hard it was pressed down.

    300- Welcome to Autopia! Yikes, sorry to hear about your oops, that could be an expensive lesson if you can`t remedy it.

    Are the defroster elements *on* the glass or *in* it? This`ll be a lot easier, well...less risky.. if the former.

    I have no suggestions..but I`d be inspecting it under magnification before I did anything.

    Re: Messed Up Rear Window...

    Find one spot that is not near any defroster wires..
    Take something really small, like a Q-Tip, apply your product, and see if you can make it go away..
    This is - Glass - you are talking about, and Not Plastic, right ??

    A plastic polish might work but keep it off the defroster.

    For some reason this won`t connect to the related post

    Re: Messed Up Rear Window...

    What kind of car? Sounds like you are in for a butt ton of work that may not pan out.... cost vs effort(plus maybe cost anyway). If your time is money I would check it out. If not.... polishing between the lines........ well good luck my friend. I hope some pro has some good news for you.
