Cleaning Windowsills Is Crucial for Eliminating Mold at Home

One of the most often overlooked areas for dirt and mold in homes is the windowsills. While many might assume that the dirtiest spots are the toilet or garbage can, it turns out that windowsills can be some of the top culprits for harboring dust, dander, and pollen. Windowsills accumulate these particles from both inside and outside the house.

Windowsills Should Be Cleaned Regularly

Windowsills also have plenty of corners and crevices for grime to hide, making them perfect breeding grounds for mold, which can have adverse effects on indoor air quality and exacerbate allergies. Mold sensitivity can trigger various symptoms, from congestion and sinus pressure to hives, brain fog, and chronic fatigue. Surprisingly, mold isn’t exclusive to bathrooms; it thrives near windows due to the moisture from condensation, creating an ideal environment for its growth.

Research conducted at the University of Arizona found that every home contains mold, with the highest concentrations often found near windows. The good news is that while windowsills and tracks may attract dirt and mold, they are relatively easy to clean. The best way to eliminate mold spores from these areas is by using a solution of ¾ cup of chlorine bleach per 1 gallon of water or a disinfectant that contains bleach. Regular cleaning is essential, ideally on a weekly basis.

Windowsills Are Easy to Clean

Cleaning wooden windowsills requires special care as wood is porous and can worsen mold issues if soaked. A DIY cleaner made of ½ cup white vinegar, 3 tsp. extra-virgin olive oil and 10 drops of lemon essential oil can effectively remove and prevent mold growth while moisturizing the wood.

For painted windowsills, start by inspecting for chipped paint and use sandpaper to remove loose areas. Then, use a mixture of warm water and dish soap to clean the sill and track. Rinse and dry with a clean cloth. Stubborn stains can be tackled with baking soda.

Aluminum window tracks and sills can become discolored over time due to sun exposure. A monthly cleaning with a commercially made aluminum cleaner is recommended. If dullness or stains persist, a paste of lemon juice and baking soda can restore their shine.

Plastic or vinyl windowsills and tracks often have weep holes that can get clogged. Cleaning these areas with a toothbrush or cotton swab is essential. Then, a simple dish soap mixture can be used to clean the surfaces, with baking soda for stubborn stains. To prevent mold and mildew, wipe them down with white vinegar and allow them to dry.

Regular maintenance of windowsills and tracks can improve indoor air quality and help create a healthier living environment for all residents, especially those with mold sensitivities.
