I have some scratches from the wiper on my Mitubishi windscreen due to old wipers ?

Can anyone suggest how to get rid of them without changing the whole windscreen. It is on the passenger side and not on the driver side so does nto cause a problem can someone suggest some kind of fluid so that I can apply on the windscreen and get rid of the round scarsI have some scratches from the wiper on my Mitubishi windscreen due to old wipers ?
Waited too long to replace the wipers huh? You can try rubbing the scratches out with jewelers rouge. It takes a lot of work but you may be able to save the windscreen. You're British aren't you? I haven't used that terminology since I sold my last MG.
