There isn't a day goes by where I don't use Trad, if you are a window cleaner you have to be able to use traditional methods.
WFP questions get asked a lot on here because there is so much to it, Membranes, Resin, Pumps, Hoses, van/trolley/backpack, brushes, jets, methods, problems and so on and so forth!
When a trad question is asked, it generally gets a lot of replies, as has been said, almost allwho now use WFP are also long term trad window cleaners...
Right...gotta go...got a pub to WFP....and then trad the inside of it
