I did my parents' house today.
It has pretty standard upvc windows with no vents.
I was really thourough on the top of the frame and the top edge of the glass.
I scrubbed lots and lots and rinsed loads.
When they dried later I found a couple were ok, but most had spots and runs.
Some were just awful.

I was really doing all I could too.
Tomorrow is the first day of work with it, and I'm not exactly full of confidence with it.
I've heard lots about spots.
I've gained jobs because of spots.
Ian showed me it in action and left spots.
I scrubbed and rinsed for ages and left spots.
Maybe it just doesn't do it right.
Maybe I'll get away with it though...

Doesn't help that my brush on the extender threaded and won't attach now.
Have to use the modular all day.
