I'm not trying to start a WFP vs Trad thing again, so please don't anyone start, and if anyone does, please don't reply to it.
However, I would like some advice as to how to clean windows that aren't new uPVC with WFP?
I've found painted frames leave spots and runs of spots, even after 3 cleans, and the same with my older uPVC windows, but only on the back of the house.
What do you do? Do you only take on plastic? Or charge more for the painted frames?
Comments Appreciated!!
Thanks in advance.
