Why Do Molds Grow on Window Sills?

Molds love damp and humid environments — places where there is little to no airflow. For example, window sills are often the perfect breeding ground for mold because they tend to be located near windows, which are usually closed most of the time. This lack of airflow prevents mold spores from being circulated and allows them to grow and multiply quickly. Contact Wisler Plumbing and Air Inc for your AC repair.

How To Remove Molds on Window Sills

Step One: Clean the Surface

The first step is to clean the surface of the moldy sill with a cloth dampened in soapy water. Be sure to use gloves to protect your hands, and scrub thoroughly until all the mold is gone. Once you’re finished, rinse the surface with clean water and dry it off completely.

Step Two: Apply Vinegar or Bleach Solution

Next, you’ll need to apply a vinegar or bleach solution to kill any mold spores that are still present. To make a vinegar solution, simply mix equal parts vinegar and water in a spray bottle. For a bleach solution, mix 1 cup of bleach with 1 gallon of water. Again, be sure to wear gloves and use a sponge to apply the mixture to the moldy areas. Spray the solution onto the sill and let it sit for 10 to 15 minutes before wiping it away with a clean cloth.

Step Three: Prevent Future Mold Growth

The final step is to take measures to prevent future mold growth. To do this, make sure to keep your window sill as clean as possible. Wipe it down regularly with a dust cloth, and be sure to vacuum or dust around it frequently.

In addition, try to keep the humidity level in your home low. You can do this by regularly opening your windows to allow fresh air circulation and keep your window sills clean and dry. You may also consider using a dehumidifier in your home if you live in a particularly humid climate. Following these simple tips, you can keep your window sills looking beautiful and mold-free!

BONUS! Safety Considerations

Always wear gloves and a mask to protect yourself from inhaling mold spores when cleaning the mold. In addition, open up windows and doors to ventilate the area and avoid using fans, which can spread mold spores. Finally, be sure to wash any clothing or towels that come into contact with mold immediately afterward. You may also call your heater installers to fix your furnace to avoid cold air in your house.
