were if it beads it can dry to quick an cause spotting
The above statement is as inaccurate as they come.
Spotting occurs if you havent rinsed adequately. The speed water will evaporate has nothing to do with it. If the water left on the glass is clean water it can sit there all day long drying or dry in a split second. Its whether theres dirt in the water droplets on the glass that is important.

Water's natural chemical propensity is to absorb dirt, that's what makes it such an effective cleansing agent. The longer the water is on the glass, the more it is absorbing dirt is nonsense. Spotting occurs only if there is dirt present. It is not related at all to the drying time.
Sorry but it can be related to drying time depending on circumstances such as
I have posted previously and types of glass do make a difference, massive amounts
of pollution on a lot of the roads I clean on and on gusty windy days when everything
is being whipped around in the air..dirt does attach itself more easily to wet glass
after cleaning, quicker the glass dries the better. I have found at this time of year
when temps are cooler hydrophobic glass(if I have the terminology correct) where
there are numerous droplets of water on the glass as opposed to hydrophilic where
there is an almost an even sheet across the pane which shrinks evenly and quickly
as drying leaving no droplets of water exaggerates the problem.
It does happen..whether you choose to believe it or not...well that's up
to you and makes no difference to me at all
