Pj - Nice job. Thanks for reporting back on the 'salty' windows issue.
I still can't understand why I had such a massive problem with them yesterday - I was really expecting all the water I was using to wash it away with ease.
I might try a different brush next time.
Thanks anyway.
Mike.
I think I know the answer, you said that the windows all sheeted nicely, and this could have been instrumental.
Pure water dissolves the salt instantly, and this dilution spreads. The actual sheet of water left on the glass is a lot thicker than you think, you can prove this by cleaning your van windscreen, you think you have a perfectly clear screen until you drive a few hundred yards without the wiper on, you will be amazed at how much water was actually still on the glass.
You can easily rinse too quick, if you bring the brush down quicker than the water runs down the glass, some water gets held up and as this still contains salt it will stay there.
If you watch carefully you will see that the water runs off at different speeds, it's as if the sheet is made of two skins of water, one runs off rapidly the other far more slowly. It's the slower moving sheet that holds a thin dilution of salt, when this dries, it looks like a light haze on the glass.
I scrub the glass, take the brush to the top of the frame, and sweep the water down to the bottom, repeat this until you have covered all the glass. Then you go back to the top of the frame and rinse slowly going from side to side, dropping your brush a few inches at a time with the brush on the glass.
It does take longer, but this is the method that works for me. Dai
