I understand that they are hard to do as you to be very careful with them.  Is their any special technique you use and what type of brush is best for these windows??
iThanks

i just treat them like any other window really. just takes a little more time on them, and rinsing more

The old single paned leaded glass you have to be carefull with, some can be very brittle as with any very old glass. I do an old 18 something school house that leaks through the glass, but the customer goes behind cleaning the insides.

I only ever use wfp on lead Glass, But agree the older style single panes do tend to leak. Just be careful if its a first clean with waterfed as the prop be loads of old soap suds behing the lead so just rinse loads for first few cleans
