Guru or God I aint.
In answer to how to clean a window, have you got all night ? I havent so if someone could help out here ? its the sort of answer you could write a book on
Because bpacs are minimalist I use about 1/2 litre/min which means that you may have to do some hphobic windows twice. Depends on 4/6/8/week rota. I am 8w so in winter its a 1 stroke clean(usually) but in dusty conditions in summer it can be a 2 stroke clean. Unfortunately for you and fortunate for the rest of the group =-so I wont get boring, I only do the glass so someone else please for the frames
First I quick wash, move to next window do that then quick rinse the previous window etc. If really dirty occasionally I may need a 3rd rinse in direct sun with dust.
I start Lt to Rt (being RH) wash the top edge of the glass and down the rt side to the frame then go back to top Lhs and wash up and down then across the window L to Rt Then I bang the brush on the bottom rt of pane and may rinse on the glass going horizontal side to side. It takes about a max of 30 secs per 3 pane window. If there are a lot of openers that could dribble down I do these first and go back later( maybe 2-4 min) with transverse cross frames I have to do the cross frame as well but leave the bottom bit till later, same with Georgians, sometimes they need to be done in rows. But theres another "book"
