Hi.

Yesterday our window cleaner came and has now started to use  a WFP.

I have read up on this system and it sems pretty good.
He spent about 10 mins, I paid him and he left.
 

A little later I went to check the windows had dried, and I wasn't pleased -

There was dirty streaks on the windows, surely if he was using purified water this wouldn't happen, makes me wonder if he's using normal tap water.

You professionals out there - does this happen to you.

Hi.

Thanks for the reply, yes I do understand it is safer for him and a lot of investment has been paid out, I will give him another chance and see if it improves this next time.

cheers steve.
