Car windows

[broken1]

I was helping my gf wash her car yesterday, it's a white mazda (non-metalic).

Well, the car is in terrible condition, never seen any sort of paint care. Didn't have time for any sort of actual detail, so we just washed it with NXTwash, dried it with my water magnets and tyre shine, vacuum, wipe down inside etc.

I wanted to get the windows clean, but i ran into some trouble. The windows looked clean, but on closer inspection - it looked almost as if they had water marks on them. I thought ok, not a prob...pulled out some household window cleaner, didn't help. I tried shower cleaner, didn't help. I eventually gave up...

I wish I had photo's of it...but if anyone can help i'd really appreciate it. How do you remove water spots from a window which have almost caked in?

I did a test spot of the DC1-2 and nxt thing on the bonnet, and you could see the white compared to "yellowish". I big difference. I want to do the whole car when there is time....

do a search, MOL has an amazing write up on using #4 for water spot removal on glass, I've tried it and it really works. This is an aggressive product so keep it off painted surfaces and rubber trim.

Well, first thing to note is that #4 isnt thaaat agressive. It is meant to be used on paint after all, just with a rotary.

But, it does work well on windows.

First however, if you have a clay bar there, I would try that first before running out for a whole new product. Sometimes it gets them, sometimes not. If the car really is in that bad of shape, maybe it wont.

Then, here is the write-up for #4 on windows:
