Well I find that View Invalid

Reason is, it will never rain just on the windows, It rains

and when it does it will run off the brick work and then onto the window....

You need perfect circumstances IE

Not too windy,, Not near the sea,,, Not near a main road

And So on..

I have cleaned in the rain and have had windows that  come up good but not all...

So I would say its down to the work you have...

You can ... I don't!

Yes Malc(G)old you are right

I did say it depends on your work.. Some of my work runs on to pipes or brickwork so I need it - for it to stop dripping..
and you dont get that if its still raining

So if your work is OK with it then yes

I'll work in strong winds (just choose lower height work to clean) and I'll work in the rain. However I prefer not to work when it's quite windy and raining heavy unless I really, really, need to catch up with work becuse I try to minimise having to go back to a customer's house to re-clean dirty windows caused by bad weather.
