Are you ready for your stained-glass windows maintenance and cleaning? Check if they’re foggy or stained and if light shines through well. If any of these things are an issue, it’s time to clean. Here’s how.

Before cleaning, you’ll need to inspect the glass first. This inspection should focus on a few key points. 

Leaded Joints

Each colorful piece of your stained-glass window is held in place by a leaded joint. If these joints are damaged in any way, your window is at risk. To make sure they’re okay, check for any separation between them and the glass itself, as well as any corrosion.

Glass Pieces

Take a look at the glass pieces one by one. Are there any chips or cracks? Is the paint layer peeling or cracking? Make sure you’re thoroughly inspecting every piece, as even the smallest chips can become a major issue later on.

Fading or Discoloration

Finally, you’ll need to check the paint and its vivacity. Is everything bright and lively, or are your windows looking dull, washed out, or discolored? 

If any of these poses an issue, you should schedule a repair. Trying to clean a damaged window can cause further damage, so it’s better to be safe. 

2. Dust the Stained Glass

If your stained glass windows are all good, you can go ahead and dust them off. Do this by using a soft brush or a microfiber cloth only. You can dampen these tools with a bit of distilled water. 

3. Prefer a Mild Cleaner

A mild, non-abrasive window cleaner is the best choice for a deeper clean. A good, at-home cleaner recipe is a soft cloth soaked in a mix of distilled water and gentle dish soap. Before wiping the windows, make sure your cloth is damp. Give your window a good, gentle scrub and dry it completely.

Another good idea is to patch test your cleaner. Pick a small corner and give it a scrub. If you don’t notice any adverse reaction, you’re good to go.

How To Restore Stained Glass Windows

Keeping the Glass in Place

Inspect the quality of the putty that keeps the glass in its frames. Should there be any loose or missing parts, replace them immediately.

Loose Glass Pieces

It is totally normal for the glass to expand and compress as the windows age. This is their way of regulating and adjusting themselves to the temperature of their immediate environment. However, this also means that the metal no longer fits the glass like it used to. If this happens, you’ll need to have the stained-glass windows re-fitted by a professional stained-glass window provider or a window installation company.

Cleaning Lead

You might have a vague idea of how lead can be harmful to a person’s health. But generally, having lead content in your stained-glass windows should be no reason for concern. However, if the metal parts that keep the pieces together start to oxidize due to age, you can easily wipe it off.

Using a pair of gloves and a cloth, simply wipe the powder-like residue off the surface. Afterward, throw the gloves and cloth away so it doesn’t come in contact with anything and anyone else. Take note, when cleaning lead keep your area well-ventilated and wear a mask.

Knowing how to take care of your stained-glass windows will allow them to continue being a decorative statement in your home. Considering that a whole window is made up of multiple pieces put together by came, stained-glass windows do need a different regimen for care and maintenance. Although this may mean that they require more attention than your ordinary windows, the personality they offer a space should be enough reason to keep them around. Any room with a stained-glass window can easily stand out.

Removing Corrosion From Stained Glass

Stained-glass window corrosion, also called white mold, occurs on the lead and solder lines of your window. It can be due to soldering residue, water damage, and more. Often present in older windows, it should be tackled immediately. 

Identify the Type and Extent of the Corrosion

Inspect all the lead and soldering lines and determine how far the white mold has spread. Pay attention to even the smallest specks and identify the source of the corrosion. 

If it’s water, check for leaks and consider moving the window to another spot. If it’s flux residue, get ready to clean it off.

Select the Right Cleaner and Tools

A cloth, brush, and gentler cleaner are all you really need to remove corrosion. You can opt for a mix of salt and vinegar or use a baking soda and dish soap paste. Of course, you can also buy your cleaner; however, you’ll need to make sure it’s gentle enough.

Gently Clean 

Use a soft scrub brush to carefully scrub off the corrosion with circular motions. It’s best to apply the cleaner on the lead only and not the actual glass to avoid damaging the paint. Clean both sides.

Rinse and Dry the Glass 

Once the corrosion is gone, rinse the windows with water and dry them off completely with a soft cloth.
