My M340i has these weird vertical 'lines' on the windscreen. It's only just developed these after a few weeks. You can't really see them when its dry but if it rains or you use the washers, they become apparent after the wipers have swept over them.
Now, the only thing I can think of is about a month ago I started using the Autoglym Polar range. So Polar Blast then Polar Wash then finally Polar Seal (not at every wash I hasten to add). I've followed the method of application and always dry the car off after I've finished, with a couple of soft drying towels. The first time I used Polar Seal though, I did unfortunately get some on the windscreen. Subsequent washes I have tried to avoid that as much as possible but invariably it will run down off the roof onto the windscreen anyway. The lines to me at least, would be consistent with individual runs of Polar Seal (or indeed Wash or Blast) running down the screen during the washing process.
Has anyone else had this with Autoglym Polar stuff or even other manufacturers cleaning solutions? How do I get rid of it? I've tried household glass cleaner like Mr Muscle - didn't look at it at all. Then I tried Autoglym Glass Polish, it didn't shift it either. Finally after browsing some detailing forums there were a few folk advocating using Tar & Grease remover. Tried that and again, didn't really help. If you use a microfibre cloth to buff up the windscreen after application of any of those products, you can almost slightly feel the individual lines 'sticking' to the cloth as you wipe over them.
It's very annoying, I'm not sure how to sort this out. Can anyone recommend a way to fix it? It gets very distracting using the wipers in the rain with every pass showing up loads of lines all down the windscreen and at night, its even worse!!
Couple of photos below, the first two images you can clearly see them - this was first thing this morning with morning due/overnight rain on the car. The one where I'm on the road (got my partner to lean over and take these before anyone asks
) is slightly harder to see, but if you look closely you can see them.
Any advice appreciated.
