I always clean in the rain, I can tell some customers do not like it, but it has to be done. I expalin that rain does not dirty the windows and it does'nt
I clean lots of houses in the rain when customers are not in. When they arrive home its all dried up and they are none the wiser and there windows are perfect. When I started cleaning in the rain I did a few experiments on my own house and girlfriends parents houses (they have a big conservatory with lots of glass, leaded pains at the top). I cleaned both houses in the pouring rain and the windows are spotless. I have sat inside the conseravtory and there are no marks anywhere due to the rain, also my girlfriends mom is the most knit picking person in the world and she cannot see any marks either.
Also: When it rains on your car windows they are not dirty when it dries.
A particular house I cleaned only twice was cleaned both times in the pouring rain, the customers were out at the time and none the wiser that the work was done in wet conditions. It rained so hard I was soaked through. On both occassions when I collected the money they commented on how clean the windows were. I turned up to clean them a third time, but this time they were in. I was told before I got out of the van 'not to clean them in this weather'. I cancelled them immeadiately. You have better things to than to clean windows 'when customers fancy it'. My mom's window cleaner has a good line when people ask him not to clean in the rain, I have used it a couple of times and it works quite well. If anyone says not to clean there windows because its raining, he says 'no problem!'. He does not clean them again and after a few months they see him in the street and ask why he has not cleaned for a while and he replies: 'Well I was going to clean them, but it looked like it might rain so I did'nt bother'. They look pretty stupid afterwards
