I have one customer who moans about wfp every time I clean, not as good as the old way, don't like water being left on glass, how can you clean windows with just water etc etc.
Explained numerous times how wfp works and she always tells me that they dry sparkling but still moans.
I cleaned today, upstairs no problem, downstairs suds everywhere, she had only gone and wiped her windows with washing up liquid. She came out and and said "there now that's how it should look when you clean windows"
