Been looking around some forums and the amount of posts there are about scratched glass, now is it the user or brushes that is doing it or are some windows like that and just seem to show up with wfp? now i dont recall many if any such posts when everything was trad! Now i am not a great lover of wfp as it seems to create problems unassociated with trad methods, scratched cills are another one that crops up! i use wfp for tops and windows i cant reach from the ground all others i do trad, i may are may not have scratched glass,cills but so far no one has pulled me up on it! i have watched fellow cleaners being rather ruff cleaning glass scrubbing like mad and it is understandable if some glass,cills do get scratched, now using an applicator you dont have to scrub like mad so why do it wfp?
