I need a bit of help- I have cleaned some leaded windows for some time now, my problem is on the bottom of the glass water seems to be building up to and not running off, customer has said that it takes time to dry and is leaving some dirty marks when dry,this has only just started happening, the water seems to collect about 1-2 cm up from the window frame! any help to sort this please.

Ian forgive me but I'm not too sure what you mean  :

Can you try to explain what the problem is 

when you say water is building up is that in between the glass ?

[Slash]

Just make sure you brush the bottom part too

[windiewasher]

rinse with brush on the glass!

As Slash said,scrub the bottom a bit more
