Wiper marks on windscreen

[rollerdan]

On my front and rear screens there are like scratch marks from where the previous owner didnt change his wipers and just let them butcher the glass . Is there a way i can buff them
Off ? Ive tried glass polish did nothing is there like a t cut or some sort to buff them out

can try a fine compound, maybe even glass cutter but i'd check with the label as they may not be suitable for windscreen

Cerium oxide is what you need.

Do some research on how to use it and take care though, you could easily junk the windscreen with it.

There's a guide on DetailingWord.

Can't you get it replaced by insurance? I'm with direct line here and they replaced it and I didn't have to pay a penny.

Get a new one or possibly try the car-pro system. Google Car-Pro glass polish.
