I have a 2007 BMW 1 series as a daily driver. Looking at the amount of damage on the wind screen I would guess it’s still the original one. It has this haze on all areas which aren’t covered by the wipers, it doesn’t usually look as dramatic as in the photo, just under certain lighting. I’ve tried strong APC, IPA and AG fast glass but no improvement. Any ideas what causes it, and if it can be removed/improved?

From the picture I suspect it's embedded dirt, however hard to determine from just a photo.

You've already tried APC, IPA and non abrasive AG Fast Glass so i would move on to clay bar the windscreen to see if that helps.
If claying doesn't help I would resort to polishing the windscreen with something like CarPro CeriGlass and a rayon polishing disc.

I wonder if that is something like Rain X on the screen and it has 'gone off'? Either way, as Enep mentioned, you may have to resort to machine polishing the screen to remove it.

Thanks for the replies, I did put RainX on it a couple of times last summer (before discovering it causes a dangerous amount of glare at night) so its possible it’s that. I’ll try some clay on it, if I get no joy I’ll look at getting kit for my DA.

0000 wire wool works well on glass

Try the clay bar, it might just be embedded dirt, then a polish

Failing that new glass

Hey Pav have you tried a compound polish any thing with a bit of cut?

PAV331 · 03-01-2018, 05:10 PM

I’ve tried 0000 wire wool, didn’t touch it. I’ve only just got a DAS6 for Xmas and I’m waiting for some scholl S20 black to turn up so I’ll have a bash with that. Not hopeful though if the wire wool didn’t make a dent. It’s weird, follows the distinct line of the wipers, even along the bottom but feels the same as the unmarked areas, no roughness to it. Might have to be an insurance job if all else fails 😔

Long shot but its not de-laminated has it.

Cant imagine if it had it would only follow the wiper line but just a taught

I don’t think so, looks fine around the outer edges, no signs of peeling/separated layers.
