How to clean your stained glass art

 Keep your stained glass looking great with routine cleaning.

Stained glass suncatchers and panels add beautiful color to any space, but like any home decor accessory, they can gather dust that dulls their shine. 

Use these tips to keep your stained glass clear and bright while protecting its delicate materials.

Why Regular Cleaning Matters

Routine cleaning removes dust buildup, which can dull the glass over time.

Taking a moment to inspect your stained glass, whether small or large, can help you catch any maintenance needs early.

Step-by-Step Guide to Routine Cleaning

• Step 1: Always remove the piece from its hanger before cleaning.

• Step 2: Use a soft, dry cloth to wipe away loose dust. An artist's brush with soft natural-bristles can help reach crevices. Use a gentle hand with light pressure.

• Step 3: Inspect the hangers for signs of wear to prevent accidental falls. If you use suction cups, consider switching to a secure cup hook or anchored picture hanger.
  

• Step 4: If dusting isn’t enough, slightly dampen a soft cloth with distilled water and gently wipe the surface. Avoid excessive moisture—water can seep into solder lines and cause damage over time.

• Step 5: Use a clean, dry cloth to remove any remaining moisture. Make sure the glass is completely dry before rehanging.

• Step 6: Stained glass often contains lead, which is safe to handle but requires proper hygiene. Wash your hands thoroughly after cleaning, and keep a designated cloth for stained glass maintenance.

Tips for Maintaining Stained Glass Between Cleanings

• Keep your suncatcher away from areas with heavy dust, grease, or humidity.

• Avoid placing stained glass near heating or cooling vents, as airflow can increase dust buildup.

 What to Avoid

• 
  No ammonia-based cleaners (like glass cleaner) – alkaline cleaners can damage metals and patina.

• No vinegar-based solutions – acidic cleaners also damage metals and patina.

• No paper towels or tissues – they can leave lint.

• No soaking in water – moisture can damage some metals and patina.

When to Do a Deep Clean

• Always start with the least invasive method, only moving to more aggressive ones if needed.

• If your stained glass is near a kitchen, bathroom, or fireplace, it may need more frequent cleaning due to grease, humidity, or soot.

• If routine cleaning doesn’t fully restore the shine of your stained glass, it may be time for a deeper cleaning. This process can include mild soap, careful polishing, and wax application to protect the metal framework. Antique stained glass windows and leaded glass windows require specialized care.  For an excellent guide on stained glass preservation, the National Park Service offers a detailed Preservation Brief.
