Tips for Cleaning Mold on Window Casings

Most homeowners don’t realize they have mold on their windows until discoloration starts to take place. More often than not, mold begins to form at the joint at the bottom of the windows between the glass and the frame. It is usually easy to see unless the mold is the same color as the frame.

Tips for Cleaning Mold on Window Casings

To keep mold from damaging your windows and spreading throughout your home, here are some smart tips from Renewal by Andersen® of Memphis, your window and door replacement expert:

Prioritize Safety

Before anything else, put on protective gear like gloves, safety glasses and face mask. This keeps you from ingesting harmful spores that mold can release into the air. You should also open your door and window to improve airflow and keep the spores from staying inside your home. Then, cover the floor to catch any of the falling mold.

Use Gentle Cleaners

Never use newspaper or other ink-based papers as they may discolor your window frames. Instead, use a non-abrasive brush or rag to prevent potential damage on your replacement windows. For the cleaning solution, use a mild solution of soap and water. If the mold is too tough to remove, it’s best to ask your window company what cleaning products are safe to use.

Control Humidity Levels

Prevention is key when it comes to addressing mold growth, and one of the best ways to do so is to maintain the right humidity levels. Use exhaust fans in rooms with high humidity like the bathroom and kitchen to reduce moisture. Depending on the kind of plants you have in your home, you may also consider removing some of them as they add moisture to the air. If condensation is forming on the windows due to the cold weather, take advantage of humidifiers.

"Our windows were the original ones that were installed when they built the house in 1972. They wouldn't open, they had been painted shut. They were single pane and the glaze was cracked everywhere. I had to put plastic up every year to help keep the house warm at least a little bit. My MIL was surprised that there weren't any panes in the windows. Now she loves it. We have put a film on the windows so we can see out but no one can see in. We are loving it!"
