    Default front window streaks streaking

    After my last service repair (brake booster repair/replace - that part went well) months ago on my year 2001 XC70 ~135K miles, I noticed that my front windshield has some vertical streaking. The service place (a Volvo dealer this time) gave me a the usual complementary car cleaning wash. I could not remove these streaks by trying to clean hard while pumping gas.
    Does anyone have any specific experience with this and a specific fix that works?
    Thank you.

    Could you post a photo showing what the streaks look like?

    Gas station water on a squeegee is usually a terrible fix for window cleaning.

    Start with a good glass cleaner. I happen to like Griot's Garage glass cleaner - works great inside and out.

    IF that doesn't work, and you're certain that the streaks are on the outside of the glass, then I would try polishing the windows with a fine glass abrasive, again, Griot's has an excellent product.

    I'm working on getting a good photo (difficult to capture streaking if too much light from phone cam), but this link has a photo that may be similar to my Volvo front windshield.

    Griot’s glass polish applied with a buffer.

    It will remove calcium deposits and other deposits that even clay bar and Bon Ami leave behind.

    I'll try the Griot's since you have never let me down, though I'm pessamistic.
    Perhaps, I'll buy you a round if you are correct, again.
    Griot's cleaner Or G's polish? The polish abrasive sounds scarey?

    The fine glass polish by Griot's. It's a cerium oxide abrasive (I think) and super fine. I've used it with a buffer - and it removes everything, but is so fine that there are no scratches.

    For things like chemical etching (which is what I suspect), this is the ticket.

    I've done the XC a couple of times with the Griot's glass polish, and it works really well. Using it by hand might take some elbow grease (i.e. lots of time and effort) but it really brings back a windshield.

    Hey Astro!
    What pad do you use with the buffer?
    Thanks!
