Mogy,

Drop him; he's obviously as daft as a brush.

You are too for even considering this request and posting it on this forum.

I thought I ask some daft questions... but well...

Is someone having a laugh here  
Doesn't matter which way you brush as long as you dislodge the dirt and then rinse it off the glass.

Did a window ground floor tday with two top openers above. The flowed very differently in the middle underneath bit to the two ends. Ians post yesterday about sheet and bead, and sheeting where he'd polished, etc.

So it might not be that daft.Finish vertical and ask him next time.

Sometimes the people making the glass get some  silicone or window glue on the glass when they are installing it and they remove it using white spirits which gets it off the surface of the glass , but glass is porous and the silica fills the teeny holes in the surface and this causes the water to react differently to where there is no silica deposit
