Cleaned my own windows today, WFP.
My two most-looked-through windows have 2 openers above one large pane.
I can get the bottom pane spotless - if I wait for the openers to dry first.
However, whenever I haven't got the time to wait for them to dry, and I just 'crack on', I invariably get a line of spots down the middle of the large pane - from where the 2 openers adjoin one another.
It's a ****** pain!
What do you do if you haven't got time to wait?
