Because if you do leave a few spots, the custies will not really notice cos half an hour later you can guarantee it will rain anyway, so if anyone is tempted to try wfp now is the time ;)

still asking for advice me, but i tested rain water and it came out at 0015,... i think its ok to work in the rain with wfp, after all... it may rain the minute you leave a house.... and lets not forget that, most "stains" on windows are caused by rain hitting the dirt....ie washing up liquid, and smearing.... with wfp and pure water, the glass is very very clean, so nothing to mix with the rain.....to dirty them.
-
Rainwater is often contaminated by the dirt on the roof etc. before it gets collected so 015 is a bit higher than rain that falls directly onto a window except if you live on the coast.

Can I work in the rain with a pure water system?
If we examine the water cycle, we learn that the water evaporates from the surface of lakes, rivers and the sea. Their mineral content is left behind when the water vaporises, which means that when the water condenses and forms clouds, the water is pure.
It is this pure water that falls as rain. The rain does not stay pure for long however, because as it falls through the atmosphere, the water molecules bind to and dissolve all the minerals it comes into contact with on its way to the ground.
While this water is no longer pure, it does have a relatively low mineral content. In the UK with our usual south westerly winds, the total dissolved solids reading of this water is around 14 TDS, with the limit for spot free drying being 9 TDS or lower. (Some tap supplies will reach 500+ TDS)
When cleaning windows with pure water, pure water is left to dry naturally on the glazing, when the rain comes into contact with this water, it serves to dilute the rain water. If an equal amount of rain water falls on the freshly washed glazing, the TDS reading of that water will then read 7 TDS within the range of spot free cleaning.
In short then, you can clean windows with pure water in all but the most torrential rain with most satisfactory results.
Many clients may well be sceptical at first, as using chemical cleaners leave a residue that becomes sticky and actually attracts dirt and that is what they will be used to. However once they have seen the results for themselves, most clients will have no problem with you calling when the weather is far from ideal.

it also gets dark by the time they get home from work so they dont get to see out anyway

Except the street lights have a habit of showing every spot.

and the low winter sun will show the spots up really bad at the weekend if we get any (and the custies WILL BE IN as they have no money to go out) lol
