Stained Glass Windows

[Bob Warfield]

I'm planning to wash our Church before the holidays. It has painted wood clapboard siding in very good condition. It's just real dirty and has a lot of mildew on it.
My question is, will my normal house wash, 15% sodium hypochlorite and Dawn mixture, have any negative effect the lead cane in the windows or the glass itself?
Thanks,
Bob Warfield

i would worry more about the glass and the cement used to seal around the frame.
Did they use a double pane system?
Stained glass on one side then clear glass on the other?
How old are the windows?
I suggest that you dont use any pressure to clean them.
I also would use the least amount of chem that i could to get the mold off.
I would use an exstension pole and wipe on the SH and use Dawn and cascade to clean with.
