I was asked to quote a builders clean for a construction company. I went round to quote it this morning and surprise surprise there are scratches on pretty much every pane.

I explained to the site agent that I would not clean them without written agreement that the windows are already damaged.

He has asked me if I could quote for sorting the scratches.

I had a good look at most of them and they all seem pretty light. I couldn't catch my nail on any of them. There were no scratches on the hardened glass on the doors.
Has anyone got a definitive method for removing scratches? I have tried cirium oxide in the past to varying degrees of success, but just wanted to know if anyone on here has a better method? If not I'll just walk away.
