Glass scratch but not a scratch as such

    Basically I used a plastic scraper to remove ice and noticed earlier that it's marked the glass:( , side window. It's not a scratch you can feel with your nail. So I'm wondering if anything would be able to remove it. Could I use compound g3 ? Or would that be too abrasive? Any other suggestions greatly received.

    I would be interested in any ideas how to fix this as I’ve noted a scratch on one of my windows and can only assume I did it with a scraper. I can feel the scratch though with my fingernail. Very annoying.

    You can start with t cut or similar and move through slightly more abrasive pastes. I have used a compound for removing scratches from watch/phone glass. Repeat in reverse order to ensure smoothness.

    It's hard work!

    To do it properly you need a polishing kit containing Cerium Oxide Powder.

    The kits usually come with felt pads for use in a cordless drill.

    Think I'll start with toothpaste then tcut, if they don't work then g3.
    I'm hoping the fact I can't feel the scratch will mean it may come off kinda easy.

    A few weeks after I bought my Leon the wiper flew off during a rainy day. Unfortunately the wiper arm scratched my windscreen. I took it to a body shop and a guy rubbed a paste into the scratch. Now it's almost invisible. He didn't even charge me. Funnily enough I managed to scuff my rear bumper today so was thinking of going back, I'll ask him what it was. I suspected it was some kind cerium oxide paste. He just rubbed it in with a cloth.

    He said the glass specialists use a compound called jewellers rouge. Apparently it makes scratches disappear completely. You have to polish it in though, and it can damage paint if not rinsed off.

    Cheers,

    I've got several fine ice scraper scratches on the windscreen and side windows of my Ibiza - I wouldn't mind that much but the car was brand new last year!
    I'm always careful to clean the scraper and apply very little force, usually the de-icer does most of the work anyway, so I'm amazed that it scratches so easily. Is the glass made of cheese?!

    I'm awaiting the delivery of my Leon ST, hopefully by the end of next week, anyway, I previously drove a brand new juke for 3 years, as you guessed it, at the time I didn't think i could scratch glass? I mean this was the first time I had actually had a new car, all my previous other cars were a lot older and never noticed a scratch like this, it went halfway across the windscreen, I actually just got used to it so never tried anything to remove it. I only had the car a few months at the time. Now when ever its frosted over I don't use an ice scraper, just get the heating on and use the de-icer, I will never use another scraper, or when ever it's snowed get out and clear the snow with my hands lol.

    You’ll need some ceriglass polish , aDA or rotary polisher with a glass polishing pad to stand a chance. Hard work tho

    I have managed to get scratches in the glass of my last 2 Leon's, so after the first time it happened, I have been very gentle with soft plastic scrapers, but still got scratches. Before my 2 Leon's, I had loads of Fords, and used to bash away with anything to hand at the time to remove frost, but I never got any scratches. Are Seat fitting a new "soft" type of glass that is not up to the job?

    Wouldn't surprise me if they were using a Spanish supplier who is making screens for their area where they hardly ever need to defrost the car.

    When I picked up my used 16 plate last year I noticed several very fine scratches. I happen to have just had my screen replaced after a lorry threw a rock at it during the winter weather. I know autoglass use their own glass but I'll be treating this one carefully. I tend to use the ice clearing sprays normally and just let them do their job and only use an ice scraper very gently once the spray has done its job if the ice is still on the screen.

    Another thing people often neglect to do is to not only replace their wipers when worn, but often they will wash the car but not clean the wiper blades. The blades harbour grease and grime which in turn can help fine sand particles to stick. Run a soapy cloth along them periodically to keep them totally free of grit. I heard if glass does get scratched, cerium oxide is the way to go.

    It's obviously the quality of glass, believe me, it happened in my 15plate juke, and they're made in Sunderland.

    Anyone tried 12v hairdryers? Or is lukewarm water more effective?

    I'm not going to be leaving my car unattended with the engine running to heat it up, so I may as well do something to speed it up while I'm waiting.

    That's exactly what I do (or used to), and I've still managed to scratch mine!!

    This happened to me with my old Leon - as above, I was using a plastic scraper back then. Now I use a scraper with a brass blade - got it from eBay (search "Murska")

    Interesting, I'm assuming that the sharpness is keeping it from catching grit or something :blink: how long do those brass scrapers last you before they get dull?

    I can't say for sure that it wouldn't allow a piece of grit to be pushed across the glass, but in the three winters I've been using it, it's been a champ - no obvious sign of degradation on the metal (the plastic handle doesn't take too kindly to being bashed though)
