thanks again,
lol... drips in my area too..
i think if i can wipe them away i would feel better.... i like to walk away fro a house knowing i have done the best i can..... yes i may be worrying too much but if i was cleaning a window 3 storeys high, how can i see it? how do i know that it looks clean?...
also can i ask one final question ( it wont be)

...
when you wash a window with wfp,, with your brush... at what point do you know when to rinse it?... if its 3/4 high, ... how do you know its clean?.... what if you rinse when it needs more cleaning, without binoculours how can you tell?........ i cant get my head around it... :

gary.
