Way to remove wiper marks from windscreen?

[blun]

Hi,

Just bought a car for my wife and, though I didn't notice at first, in bright sunlight you can see a mark on the windscreen where the wiper has marked it. It's got decent new blades on now so I suspect this has occurred in the past.

Running my finger over the mark I can't feel it at all - is there anything I can do to get rid of it?

Thanks

Thanks for the replies. I did actually try claying it as I happened to have some to hand - not sure it's made much difference though.

I'm not sure if its actually scratched - it doesn't feel like it is, but it doesn't seem to want to go away!

It's really not bad enough to warrant replacing the screen to be honest. Just slightly visible in bright sunlight.
