How to polish scratches out of glass

I don't know how but my wife has managed to scratch the side window of her car when scraping frost off it. The scratches can be seen and felt with a finger nail. Is there a way to polish out these scratches or at least make them less noticeable?

Cant help with the solution, but most likely cause is diamond rings....

or titanium rings!

This question seems to get asked every couple of months.

Might be some answers if you do a search

it can be done but it takes forever. last year some ar$e stuck a notice to my wifes car window with what must have been superglue. in an attempt to clean/scrape off the residue with a combination of chisles and emery cloth she managed to make a right hash of it!

I started off with ultra fine wet and dry to cut the class back to the level of the scratches and then slowly, using a rotory polising attachment on my drill and various cutting polishes (including T_Cut, autosol chrome polish and ending up with brasso). turnrd out fine but took about 5 hours all in all.

I have used these before but i think they are really for polishing up where class has gone a bit dull. i dont think youll be able to get down to a scratch that you can feel when you run your thumb over it.
would probably work well once you were able to get the scratch flattened but worth a go anyway as its very daunting working away at your window with wet and dry!

i used to polish glass at university for analysis, and they had to be perfect! I hand polished my samples with varying grades of SiC papers to about 600grit and the final step was to use Cerium Oxide as a polish. You can find it on ebay

if it doesn't work then you can get replacement from breakers quite cheaply (not a popular item).

[Edit: I love this place. You learn loads!]

Brasso has saved me in the past. It was the only thing to take small scratches out of mineral glass watch face. It worked a treat, so I'd have thought it would be worth a shot. (Discovered this when I was a kid. Perfect timing - Mum was none the wiser! ;-)

Or maybe one of those nice windscreen-repair blokes might be able to fill / refinish it if it's deep?
