How to Keep Them Clean
What’s the best way to keep stained glass windows clean? If you dust the surfaces with a soft brush or dry cloth, you should be good. If you think there’s a need for a more intense cleaning, then use a soft cotton cloth and pH neutral solution mixed with water.
What to Avoid Doing
Basically, when cleaning stained glass windows, you want to avoid using any acidic solution. Therefore, avoid products with ammonia or vinegar in them. Acidic solutions can attack the metal structures holding the panes of stained glass together– so you don’t want to weaken them.
Also, don’t use a scouring pad or washing powder because those things scratch the glass. Interestingly, you could use crumpled-up newspaper to clean your windows, as well as old rags or even old toothbrushes. For those tiny pieces of glass or when you need to reach into a tight corner, try cotton buds/cotton swabs– you know, the kind most people use to clean out their ears.
Plane by Plane
It’s best to clean pane by pane. Don’t spray liquid directly on the glass. Instead, spray it onto your cloth. If and when you find streaks on the window(s) afterward, you can use a dry cloth with a small amount of dry whiting powder to help eliminate streaks and marks.
Sometimes people find loose things on their windows, including metal reinforcers or putty. Typically, if they find something loose they just tear it off and throw it out without much thought… but that’s not good. Loose things on windows need to be repaired or replaced. Also, over time window glass may expand and contract. When this happens, the metal doesn’t fit the glass properly. Bars may break. Again, this is the time when you need professional restoration work done so your windows won’t have further damage.
