scratch on glass?

The best system to use right now is Glasweld. It's a polishing system used by many glass shops, automotive and building. It can actually take the glass that was not removed and replace into the scratch without causing a distortion to the glass. I recommend calling local glass shops and see if they use this system. They may charge labor to polish the scratch out and there is probably no way to estimate the time involved since they won't know how long until they do the job.

Depends how deep it is - if you run a fingernail across it and you can catch your nail in the scratch its too deep to polish out.. If you can't feel it then you a glass polishing kit using cerium oxide might work. Screwfix sell one that I used to take some scratches out of a fish tank. Costs £19.99 & works with patience.
