Did few cleans yesterday,snowing plus windy, as did a mate of mine,
Had a complaint, went back, loads little milky coloured spots.
I am assuming the snow has whipped up some dust etc , and as the snowflakes have landed on the window and dried, hey have lef spots?
Any help be appreciated

Tip. dont work when snowing or when very windy.

Snow wasn't the problem, the wind was. Still very strong winds today, no snow, but there were very obvious dust droplet marks on the window. Very much depends on the location.
Rain or snow + very strong wind can result in problems.

check your tds ;)

Super cooled water (unfrozen water at below 0C) high up in the atmosphere, as it falls, needs a dust particle to form around to turn into an ice crystal.
A snow flake is made up of tens and tens and tens of thousands of small ice crystals which then coalesces while falling to form a snow flake.
Maybe it's the relatively huge amount of very fine dust in a snow flake?
Maybe?

I find snow and ice cause no problems, apart from freezing the spray from fanjets :o

I agree, but it only becomes a problem when the wind drives snowflakes onto the glass. They then melt and deposit their tiny bits of dust which cause the spotting.
