Get ready to lose quite a few customers if you try to do these WFP.
I don't care what anyones says but WFP WON'T do a decent job on any windows with oxidiese frames.
We dpn't take them on any more because they are so much hassle.

that turned the water a milky colour the first one or 2 cleans , don't give me problems
now, even the white coated windows can be cleaned , if you know wat you are doing,
