Current Events > Can you use regular window cleaner on stained glass?

(+) Yeah! (+)

My apartment has these little stained glass windows and I want to clean them good now that its getting sunny out.

google isnt helping because it thinks I mean windows stained with dirt >_>

First thing I googled had this to say:

Choose cleaning solutions carefully.
Whether composed of painted, textured, or tinted glass, Seekircher says that all stained glass needs to be gently cleaned with a nontoxic cleaner. "Never use a cleaner with alcohol or ammonia, because it can damage the solder that's holding the window together," he explains. Additionally, Blyth says to avoid using dish soap when cleaning leaded glass, because the ingredients can react to, and discolor, the frame.
Consider a foam cleaning spray.
When in doubt about what cleaner to use on your windows, both Blyth and Seekircher recommend using a foaming spray, such as Sprayway Glass Cleaner Foaming Aerosol Spray ($3.27, homedepot.com), to play it safe. "Foaming spray from an aerosol can ensures that leaky lead joints won't seep liquid through to the other side," he explains.
Dry everything off with microfiber towels.
For drying, a microfiber towel, Blyth says, it's your best option. "Microfiber towels are key to both cleaning and maintaining stained glass windows," he explains. "Not only are they a gentle and effective way to clean and dry stained glass, they can also remove dust, dirt, and other residues from glass without any spray between cleanings."
Always be gentle.
Stained glass requires a delicate touch, so Blyth suggests folding a microfiber towel into quarters to help distribute the pressure from your fingers over the surface area. "If you have a really large surface to clean, say taller than six feet and wider than three feet, consider a boar's hair brush to perform the initial wetting and scrubbing of the window," he says. If you're dealing with an extra delicate piece of stained glass, Seekircher recommends spraying your cleaning solution directly onto a microfiber towel, and not directly on the window, to avoid over-saturation.

Yes.

Unless it's fake stained glass.
That I don't know about.
