Water spots on glass

[Camberley 28]

Just wondering if anyone has a magic solution to removing water spots from the glass on my e38? Cheers

Megiuars do one I have had good results with 

But I would recommend talking to Sam at United Car Car,  he is a super helpful guy and would have good recommendations

I think Autoglym do a glass polish.

Thanks for those suggestions.  I will follow them up.  I have tried several "google" ideas but with little or no success.

I’m pretty sure I used a “soft” regular car polish on my last car. Worked fine.

I used one of those shower cleaners with good results, if you have that around. The ones that are meant to clean water spots from shower glass.

Just keep it off the paint, or follow it up with detailer or wax.

To keep it clean in future use a glass cleaner with a water repellant coating on the outside, or apply a coating. Helps greatly with visibility in the rain too.

The branded glass polishes work but because they are a single stage abrasive they are relatively weak. If you dont have a proper buffer you will probably be looking at 15 minutes per window for moderate improvement or 1 hour per window of hand polishing for total removal. 

If you can acquire a buffer preferably with a hard foam compounding pad or similar you can do this perhaps 5x faster.
