How to clean leaded windows
Just in case you're not familiar, leaded windows (aka came windows) are windows made up of many small panes of glass held together by lead channels called cames. Decorative stained glass windows are came windows. More commonly, at least on houses, they are simple grids similar to how french panes are arranged, although they are sometimes on the diagonal.
So, to those of you who know what I'm talking about, how do you clean them? Do you take any special safety precautions (because of the lead)?
I encounter these fairly often on older houses. I've always treated them the same as frenchies, washing and detailing each individually, but I'm wondering if there's a better way. WFP is not an option. At best, you'd get water leaking through. At worst, you'd just break them.
