gary i go over the top sills with my brush a few times(water off)then i can start on the window directly underneath or to the side(where there is no window above!)i never stand around waiting!time is money!!

sod that i never bother waste of time on a maintainence clean on my four weekly work
windows and sills are barely dirty in fact on the new builds i clean i dont even rinse unless
something major is on window. straight across tops no hanging around straight onto bottoms
they always come up spotless.
i dont know amateurs eh!
