Cleaning Black Mold From Window Sills

How to remove black mildew from wood window sills step 1.

Cleaning black mold from window sills.

Vinegar and ammonia can substitute for bleach if necessary. Place undiluted white vinegar in a spray bottle and spray the sills and frames. Add caulk to the window edges to stop leaks and wipe away. Let the vinegar sit for an hour before rinsing.

Dampen a clean cloth in cool water. Keep window caulking and weather stripping in good shape. Although mold flourishes in a moist environment the spores will enter into the air as you re removing them so if you dampen the sills you re essentially gluing the existing spores down. To prevent the mold spores from entering the air dampen the affected area with a spray bottle.

However it can penetrate into the roots of the mold and can kill and remove all traces of mold. Tea tree oil is the best treatment for killing and tackling mold on window sills unfortunately it is the most expensive option too. This is just one property of tee tree oil and is something you should have on hand at all times. Spray the mildewed window sill with the mixture and let sit for 10 minutes.

Fill a spray bottle with white vinegar. Scrub the area with some elbow grease to break up the mold particles. Once the mold has been scrubbed use a damp microfiber cloth to wipe the surface clean. Vinegar is a good option in cleaning black mould from these areas.

If more mold remains repeat the process until it has been removed. Pay extra attention to windows in damp rooms like the bath and laundry. Put on gloves a face mask and safety goggles. Scrub the black spots and then spray generously again.

Wet a toothbrush with the cleaning solution of your choice. Alternatively mix 1 cup oxygen bleach with 1 gallon of water and pour.
