I am a trad, and intend to remain so indefinitely, but fully respect the freedom of choice we all have to use trad or wfp methods.
Interestingly, I picked up two customers the other day who previously had wfp window cleaners. The custies were unhappy that in particular the upper sills hadn't been cleaned, despite repeated asking and getting promises that they would be done.
The sills were UPVC (originally white, but over time had become resplendent in green). Two minutes with a damp microfiber sorted them out, and I now have 2 very happy new custies. Wfp guys, how do you ensure that upper frames and sills are cleaned properly? (Not having a go, just asking a pertinent question).
