Stained Glass Window Maintenance
Once a window is cleaned and installed, it will require only occasional dusting. More difficult dirt can be cleaned off by the use of water and mild detergent. Never use an abrasive agent or steel wool. However, when you first purchase a window, the glass often shows the dirt and grime of many years. As a general rule, we would suggest the following approach:
1. For general grime and soot, use a mild dish detergent and a cloth (do not use paper towel, as it will "catch" on the lead).
2. If the glass surface is highly textured, you may have to use an old toothbrush to clean out the folds and indentations in the glass. The brush can also be useful in getting in close to the lead.
3. The original house paint may have been splattered onto the glass. These splatters can usually be picked off with a knife or chisel. Paint smudges may be gently rubbed with steel wool (on glass that does not have original hand painted pictures/scenes).
4. The original house paint that extends onto the lead should be left alone. If you scrape away that paint, you may scrape away the oxidized surface of the lead as well, leaving a shiny lead surface in its place.
5. The residue from any price sticker or label can be removed with varsol or lighter fluid, then washed with soapy water.
