Hi
First time in 4 months got a call back on a first clean!

TBH there were some spots and a couple of runs on the window but you had to look for them - got two neighbours who I don't think like the system geeing each other up.
The single unit windows were fine.
The problem was the units with a fanlight or crossframe.
The top panes were ok it was the bottom ones under the fanlight or crossframe that were spotted or had runs.
I wash all the frames and windows all around.
Then go back around washing the glass again but not the top of the frame then rinse at least twice.
Do you rinse the frame at the bottom of the fanlight?
Cos that is the only thing I can think of that is causing the runs down the bottom pane.
Either that or it is coming out from the back of the closed fanlight.
