Step 1: Prep the Area

Put on your gloves and eye protection. Open windows nearby to help ventilate the room and ensure any pets or children are out of the area. Thoroughly clean off dirt, dust, and debris from the windowsill with a damp cloth.

Step 2: Mix Cleaning Solutions

Mix your chosen cleaning solution in the bucket with warm water and soap, following the directions on the bottle. Mix 1 part vinegar with 1 part water in a separate bowl for a natural cleaning option. Always test your solution on an inconspicuous part of the window sill before applying to ensure it won’t damage the area.

Step 3: Apply Solution & Scrub

Apply your chosen cleaner to the mold-affected area using a rag or paper towel. You can also use an old toothbrush to get into small crevices. Gently scrub away at any remaining mold until it has been removed.

Step 4: Rinse Away Mold Remnants

Once you’ve removed all the visible mold from the windowsill, rinse away any residue with clean water and a cloth or rag. Make sure to get into any nooks or crannies where mold may have been hiding. If you’re using the vinegar solution, rinse with water afterward for a more thorough clean.

Step 5: Dry Windowsill Completely

Dry the windowsill thoroughly using a clean towel or cloth. This is very important, as moisture can be an ideal breeding ground for mold if not completely dried off. Use a fan or hairdryer to speed up the drying process if possible.

Step 6: Apply Mold-Resistant Paint

If desired, you can use a paint specially designed to reduce the growth of mold and mildew on your window sill. Follow the directions on the bottle and apply two coats, allowing each coat to dry in between applications. As with the cleaning solution, always do a test patch first to make sure it won’t damage the area.

Step 7: Check For Leaks

Inspect both the inside and outside of your home for any water leaks that could be causing the mold problem. If you find any, make sure to repair them immediately in order to prevent further mold growth. Always make sure to use a water-resistant caulk or sealant when making repairs.
