I virtually always rinse on the glass, there are occasions when you instinctively feel you have to rinse off the glass.
I also have quite a low flowrate too, and to date, rarely have any problems.
My general technique for repeat cleans on windows and frames in good condition:
1. Side to side a couple of times on the top of the window frame, and usually down the sides of the frame.
2. side to side quite quickly of the top of the glass where it meets the frame or glazing.
3. vigorously up and down moving along the width of the pane and quickly working down the pane, depending on the size of the pane of course.
4. With windows that have panes below I then wash the frame between the panes and continue down and across the rest of the window, finally finishing on the sill.
And thats it, when I scrub the glass I don't just pass over it once, it is scrubbed several times as I pass down the glass and on good windows that is more than enough.
There are many variants of course, you can tell to a certain degree by the 'drag' on the brush as you clean that you may need to go over the entire pane more than once, you can see the effect that the weather has had on the glass, and that can also tell you that you may need to take a little longer or adapt your technique.
Some windows have vents..well we all know we need to be very careful around them.
And if frames have oxidized you have to further adapt your technique.
I am using the superlite pole and brush, and have found this a good combination by the way.
