Does anyone know the best way to remove rubber smear marks from a windscreen? I have a blotch about 3 to 4 inches across directly in my line of vision, it isn't there when it's dry and only shows up when it's wet and the wipers are working so it it's not a scratch, so was wondering if there was a way to clean this area without scratching the glass as I only had a new screen fitted last September.

Thanks

Try a little vinegar on some newspaper, it is a very good way to remove grease from glass.

Failing that a mild abrasive like Jif (Cif now ? ), anything that can be used on ceramic hobs/pyrex as they are about the same "hardness" as windscreen glass.

Thanks, I did think about Cif but was a bit worried about using it.

thanks

i had a problem like this ,, i got some new blades ,, gave the window a good clean inside and out ( used some car glass cleaner i had floating about ) , and then got some rain repelent , hope this helps might solve your problem

You have tried with a tar remover in spray? Or a good cleaner for the rims? Or with acetone...

The blades were replaced a week before the screen with Bosch ones so they 'should' be ok, but I will give it a clean with vinegar and newspaper then give it a once over with cif tomorrow

Thanks

If all else fails I'll look at commercial products, but I'm going to try cheaper options first (I know I'm a tight wad  )

Parafin does the same job I believe.

Maybe yes, I never use paraffin. I think that acetone can also operate, and it's not expansive... Tell us about

Mr Muscle Glass Cleaner.

Removes all the road grime/oil/grease, etc....and dries smear free.

All of the advice will work but be wary of the Rain Repellant, I used it and later regretted it when the wipers eventually removed sections of it. It left the screen in a right mess and it was only by using raw Cellulose thinners after I had tried everything else very, very carefully that I eventually managed to get rid of it.
On any glass where there are no wipers it works brilliantly though so it was not mis-described - it does what it says it does and repells the rain (mist too). I still use it on my side windows (home ones too).
I also used it on my headlight lenses but they too deteriorated for some reason that I could only put down to the heat generated by the HID bulbs. That was even worse to get rid of because the lamp lenses are plastic.

Cheers guys, plenty of options for me to try. it's been annoying me for ages, the rest of the screen is crystal clear except for that one small area sods law at work again I guess.

I had the same trouble after a new screen was fitted along with new wipers, gave the sreen a good clean with autoglym glass cleaner, that did the trick.. give it a go..

that cheap T-cut is good and rain dont stick to window, dont use the good stuff, leaves a layer on the glass and get glare back from lights at night but the cheap stuff dont do that.

now dont be funny but caravan window cleaner is good at getting rid of the yellow colour of the plastic lenses, used on old head lights until the reflectors went.
