Did BMW put some sort of wax on the windows?...weird
Can you specifically list the products used? Please don't use steel wool or a magic eraser on your windows...you can definitely get scratches and then you'll have to polish your glass.

A really good rule of thumb in detailing is always go with the least aggressive method first and then work your way up. Once we know what you have been using or get some pics we can help you resolve the real issue.
