scatched windscreen

[omodos]

hi all, in all my years of motoring I never took to cleaning a car windscreen with a dish sponge....but did on the x5 and noticed that I scratched the windscreen! numerous hairline scatches only visible in certain light conditions but scracthes are visible and annoying as they catch the light.....is there any off the shelf product to reduce these?kicking myself for doing this damage....pretty sure scouring sponge must have had specks of sand in it causing the damage...called a local windscreen chip repair company and they said they don't do the repairs anymore but to take it round to see if it can be polished out...

ps tried to take pictures but the scratches dont appear in photos
