Have been watching alot of videos as changing over from trad to wfp. What I've noticed on YouTube is the people doing it trad are more like frame restorers . Getting all the marks of the frames sills etc. Surely I'm not the only person who does none of that?. There's hardly any on my run where the soap has to be taken of the sill, it's a case of clean the window then next one leaving the soapy sudds behind. It would take about an hour to do 2 houses doing it the way in the videos.
