I had some pretty bad ones and i tried tons of different polishes and rainx, nothing worked.
I put some coke on a microfiber cloth and wiped in it the window. Finished off with Lusso glass polish and low and behold the combo worked.
Just thought I would share in case anyone else is running into the same problem

My Ride: I have an 05 545i. It's a manual with a few options. This is my first BMW but I don't know how I'll ever be able to switch to something else.
I've heard of this before, the phosphoric acid in it is the reason. Though I don't like the thought of putting coca-cola on my car 
I'll stick with my Sonus glass polish

Since it's glass a mild acid should be ok but I wouldn't use it on bodywork. Lemon juice is also a mild acid and should have the same effect.
