Hey all! I'm the new lucky owner of a great Alpine White 328xi CPO. When I brought it home and washed it for the first time I noticed heavy hard water spots on the windows throughout the car. (posted picture in thread here: http://www.bimmerfest.com/forums/showthread.php?t=547215)

I've tried what seems to be everything. Clay Bar on Windows, SwirlX, White Vinegar. Nothing has shown even the slighted bit of improvement.

Does anyone here have any suggestions!?

Get some 0000 steel wool, that should take them off. If not then this will

I've been told by a local glass business that the A-MAZ Water Stain Remover should eliminate the hard water spots. However, if it doesn't do the trick, the water spots are permanently etched into the glass and the only way to resolve this is by replacing the glass.

I've placed an order for the A-MAZ today and will report back my findings shortly.

I have this as well, and it does a great job on water spots

You have several options.

Believe me, here is Portland I get my fare share of waterspots with 8 months of rain per year. :thumbup:

Always try the least aggressive method first.

For me that is HD UNO and an orange spot polishing pad

If the pad is not doing it fast enough, I use HD UNO and 0000 steel wool.

Here is the HD UNO/ foam pad combo in action

Another option is a dedicated Waterspot remover.

I just ordered some due to your endorsement. It will be headed straight for shower glass once it arrives. :) I never thought to look for water spot specific products before, and would only use white vinegar for this kind of thing (with mixed results, but better than anything else I've tried).

Wow! Simply amazing... This product ROCKS!!! I've tried all kinds of remedies to remove the hard water spots and A-MAZ is outstanding.

Thanks dboy11 for the recommendation. It was worth the time and effort to eliminate years of neglect on the windows. Next, I will replace the weather stripping :-)

use diluted lime away (or equivalent), but stay away from the paint.

AMAZ did a great job on shower glass. While it still required some elbow grease, it was still easier than with undiluted white vinegar. I saw on the mftr website that it works well on toilet rings, so I went at it, in combination with a new pumice stone (also a first here), and that worked better than anything else I've tried (though I think the pumice was the most responsible here).

Anyway, now that the glass is pretty good, I can't help but ask, what am I supposed to seal it with? :D Are automotive sealants resistant enough to hot water, and are adverse health effects nothing to be worry about here? I have LSPs from Menzerna, Megs, 3D, Dodo, Sonax, maybe more. Maybe the Powerlock? I imagine carnaubas wouldn't last long at all, but then I suppose any adverse health effects are much likely to occur with carnaubas? Thanks, and excuse the hijack!

You know I saw that while shopping AMAZ, and I don't know why I was dismissive, maybe because I was thinking I had so many (automotive) products already. I think I might end up giving it a shot after all.

I forgot that I have some not so cheap Aquapel applicators (I think they work fantastically on car glass), maybe I should try those. I just wonder how much the heat of the water might kill it off, especially because of the cost. Hmm.

Glad that it worked for you. I did our shower door as well and it looked new.

When I get details that have waterspots. I always do the pasting of the windows with Amaz at the wash stage. Then I can wash it all off with soapy water and the windows come out perfect every time.

Collonite Insulator wax would be a good choice..Its designed for marine use.
