dont forget it can take  3 cleans before the frames and glass are fully cleansed

thats not totally true, or it's misleading 

let me correct what i should have said  you should always inform all new customers of the 3 cleans, you either charge for the first clean, and spend the time there to get it cleaned first time round, or do 3 fortnightly cleans before starting a monthly or 6 weekly clean, thats how i do it,

start at the top work across then do the downs ,

Exactly.

Particularly this time of year when all the leaves and crud is coming off the trees a house underneath or close to trees a week after doing the job WFP is likely to have those windows immediately in the firing line spoiled.
