Stained glass windows are charming and even awe-inspiring, but they inevitably become dirty or dusty. In most cases, these windows require specialized cleaning techniques to prevent damage or the spreading of lead dust. Understanding how to clean stained glass windows (or leaded glass windows, for that matter) is essential for preserving their appearance and structural integrity. Here’s how I go about it in the simplest, least expensive way possible.
Stained Glass Window Cleaning Steps
If you take one thing away from this tutorial, it’s that you need to be gentle when cleaning stained glass because the materials are delicate and can easily be scratched, discolored, or damaged by aggressive cleaning methods.

Before beginning, carefully inspect the window for any cracks, loose lead, or other damage. If you find any issues, consult with a professional before proceeding.
Use a soft brush to gently remove any surface dust, dirt, or cobwebs from the window. Be gentle to avoid scratching the glass or dislodging the lead.
• In a large bucket or container, combine dish soap and white vinegar.
• Slowly add the gallon of distilled water to the soap and vinegar mixture, stirring gently to ensure an even distribution of the ingredients. Pour the solution into a spray bottle.
Test the cleaning solution on a small, inconspicuous section of the stained or leaded glass to ensure it does not cause any discoloration or other issues.
Spray or gently apply the cleaning solution to a small section of glass using a soft cloth. Work in small sections to prevent streaking.
Using a soft microfiber or cotton cloth, gently rub the wetted area in a circular motion. Avoid putting pressure on the lead or solder joints.
Use extra caution when cleaning the lead. Wear gloves, gently wipe the lead with a damp cloth, and be careful not to bend or damage it. Continue the process, working in small sections until the entire window has been cleaned.
Rinse the cleaned area with distilled water to remove any soap residue. Use a separate clean cloth to wipe the area dry. Using distilled water when rinsing is essential to avoid mineral deposits that can be left behind by regular tap water, which may cause unsightly spots or even potential harm to the stained or leaded glass.
Inspect the window for any missed spots and wipe it down with a dry cloth. Allow the window to air dry completely.
Warning
Don’t use too much water, especially near leaded joints, because excess moisture can seep into the cracks and cause the lead to oxidize or the surrounding wooden frames to swell and deteriorate.
