    This guide is to cover the removal of scratches from Glass. Glass as in your windscreens and automotive windows NOT the plastics on Motorhome windows.

    Polishing glass can give huge rewards especially if your windscreens have become scratched from say a rogue wiper or has become swirled through washing or even scratched on the inside fro diamond rings on fingers when wiping condensation away.

    The only screens where care must be taken are those with heater elements in them like many Ford or Jaguar vehicles. All the rest carry little or no risk of damage but Always try a small area out of site before committing to a full window !

    For glass we use a product called Cerium Oxide. This comes in a powder form and is mixed with water to a fine paste and applied to the window on a soft to medium pad and polished by machine.

    Polishing by hand would not be possible in this area as it would take an enormous amount of time !

    Polish by machine using a soft to medium hard pad at low speed. Number 2 or 3 is about right.

    It doesn't really matter how deep the scratches are on normal glass as you can polish quite deeply (Within reason and paying attention to heated screen elements) .

    I have removed really deep scratches from glass even when done by the dreaded diamond rings.

    A heavily marked sometimes lightly chipped screen can be restored to true optical clarity ! Better than new in fact !

    Cerium Oxide is available of Ebay for very little money !

    Thanks for this - I have a windscreen with lots of small haze scratches from previous owner using the windscreen wipers with grit on it.

    I also have some scratches that I caused on another vehicle when using a cheap screen cleaner that scoured deeper scratches into it - would a coarser grade be better or should I spend longer using the fine grade?

    9 times out of 10 the light grade will correct perfectly.

    Using a light cut grade or polish will give the same results as a high grade cut only slower.

    Plus some high grade polishes will need following up with a lower grade to refine the finish to achieve in this case ultimate clarity.

    So go light grade / cut and see how you go .

    I've used this stuff to polish scratches out of plastic windows.


    It works well and isn't expensive. It was recommended here on MHF.

    Believe it or not my van a 2013 AS Kemerton has just had a really in depth under body clean.. I have access to a workshop with a lift and the under body will be getting sealed with either Dinitrol or Shultz .

    Trouble is when I get a vehicle completely finished I get bored and end up selling them... Just me as mad as a bag of adders...

    Enjoy the rugby !

    You can use Cerium Oxide on All glass.. From watch faces to vehicle windows. Same results on all. (y)
