Hi all, just wondering if anyone has any ingenious techniques or products that can reduce the effect of scratches on glass.
It looks like a previous occupier tried to do some cleaning with 60 grit sandpaper on my windows, pic below… the cleaner you get the glass, the more you notice it 
Thanks, Tom
I’ve had some success with a windscreen refurb kit (from a motor factor’s or Halfords) - but those scratches look quite extreme in your photo. Also that refurb stuff needs a fair amount of pressure on the pad and a polishing wheel in an electric drill, and windscreens are really strong… you’d need to be careful on plain flat window glass…
On the other hand, a windscreen is typically harder, so less aggression might be needed here? (But I’m only guessing.)
Difficult to see how anyone could have caused that much damage by accident - even if you had a bit of grit caught in a cloth, surely you’d know at the first wipe?
Whenever I’ve seen that it’s usually someone wiping away condensation while wearing a ring with a stone or something
Not sure it makes much difference how it happened in terms of fixing it but that’s a quite common cause especially in cars…
Thanks both. Maybe I will have a go with one of the windscreen repair kits and see what happens.
Thinking about it I suspect whoever did it was trying to rub down the paintwork rather than clean the glass… quite a big miss though!
Did you have any success with this, Tom?
I didn’t end up trying it on the window in the picture as the scratch was on the outside and I’d already reinstalled the sash.
I do have another window to refurbish and there are probably some scratches on that one too so I may well give it a go there… will post here if I do.
Hi,
why not use a smart fill resin (its the same type they use on car windscreens to fill chips and cracks to the glass ) I hope this is of some help . Brian D=
It looks like a bird tried opening the window.
