Hi All,
When I first started WFP Phill Washington Thomas ( a member on here and a good friend of mine) showed my his system and said
"If you wet it, wash it!" refering to any part of a window.
He meant that if you get water on any part of the window and don't wash and rinse it then dirt will run onto the glass!!.
The other pearl of wisdom was way back in 2004 when a chap said about WFP
" WFP is not a 'Magic Wand'"
