Tip

Open the window for ventilation and easy access while cleaning.

If the mold is growing indoors, set up fans or a dehumidifier to increase airflow and reduce humidity. Repair any leaks to prevent excess moisture.

Mold on window frames can be the result of exposure to excess moisture. Whether it's caused by rain, humidity or condensation, mold growth on window frames can be unsightly and exacerbate respiratory conditions such as asthma if it grows indoors. Mold usually gives off a musty odor and can appear in patches of black, brown, gray and other colors. Chlorine bleach commonly is used to kill mold spores, and is safe to use on wood, metal and plastic.

Step 1

Fill a bucket with 1 gallon of warm water and add 2 or 3 teaspoons of laundry detergent. Put on rubber gloves and an N-95 particle mask.

Step 2

Dip a sponge or scrub brush into the cleaning solution and thoroughly scrub the window frames to remove any mold. Rinse the sponge or brush in the bucket as needed.

Step 3

Dampen a cloth with water and wring it out. Thoroughly wipe the window frame to rinse away any detergent residue.

Step 4

Empty the bucket and rinse it out. Fill it with 1 gallon of water and add 1/4 to 1/2 cup of bleach.

Step 5

Dampen a cloth or sponge with the bleach solution and apply it to the window frame. Make sure all affected areas are covered with the solution. Allow it to air dry. There's no need to rinse.
