Leekson's, on first cleans, especially when you first start with WFP, it's better to go over-the-top; than to be economical with your calories and your water.
But I agree, yesturday and today, with the hot sunshine, I did have a few problem windows.
Most came up great (I think), but one or two were awful.
So I avoided the frames where I could this afternoon, and spent a little bit of extra time on any transome bar (I think that's what they're called; the bit of the frame between panes of glass that your water runs over).
Hopefully a more experienced WFP user will give a bit of guidance.
PS.
Squeaky, I'd be gratefull if you'd not turn this thread into a WFP versus ladders thread. I'm posting as a member, not a mod, who'd like some genuine advice.
Thanks mate.
I'll buy you breakfast on Tuesday!
