ok, so i gets a phone call this afternoon from a custy...
"im not happy that your pole thingy as left water marks again (this is not the first call ive had from her like this) ive even tries leaning out the windows and polishing them off myself but they wont polish out"
so i go round and go inside and upstaird to take a close look, she's right, they are hard water marks! i got my trad gear out and cleaned the glass and there still there on the glass
now ive got some hard water removing chemical if push comes to shove but how in the hell can my pure water (ive never used water over 12ppm and now only use 000 ppm) have left hard water marks
my first thoughts were that they must have been there a while before i started cleaning her windows! they are only at the bottom of the glass about 6 inch up from the bottom!
has anyone else had problems with water staining from w.f.p? or a situation like this?
help!
