They are not windies then in my eyes.I agree we are fully wfp but still use trad for internal on commercial work and a very occasional shop front , but the latest cleaners I talk to arnt interested in Evan having trad gear they just refuse point blank to do anything other than wfp jobs
A window cleaner will use whatever method needed to clean a piece of glass.
I fan with 1 hand while soaping up the next window with my other if tradding.
Or soap up a conservatory and use a squeegee in each hand to do 2 windows at once.. only took me 30 years to get this good lol.
