How do you get rid of black mold on window sill?
Apply a 50/50 mix of water and white vinegar to the window sill and let it sit for about an hour to kill off all the mold. Wipe the area clean with a dry cloth. This mixture is gentle enough to use on both porous and non-porous surfaces.
Vinegar has anti-fungal and antibacterial properties, and it can be a cheap and effective treatment for many types of mold. Household white vinegar typically contains about 5 to 8 percent acetic acid.

Can I mix vinegar and bleach to kill mold?
The short answer is no, you shouldn’t. A combination of bleach and vinegar is not recommended to treat mold growth. Mixing these two powerful chemicals releases a toxic chlorine gas and can cause serious harm!

Why you shouldn’t use bleach on mold?
Mold loves water. When bleach is applied, the chlorine quickly evaporates after use leaving behind a lot of water. This water often soaks into the porous surface allowing the mold to flourish and re-grow in the moist environment. Bleach feeds the internal mold spores.

Can I leave vinegar on mold overnight?
Spray vinegar onto the moldy surface and leave it for an hour. Then wipe the area clean with water and allow the surface to dry. Any smell should clear within a few hours. While it’s safe to use on most surfaces, vinegar is unlikely to be effective at cleaning mold off of soft surfaces.

Ways to Prevent Mold Growth
Keep ceiling vents open at all times.
Frequently clean your home’s windows (inside and out).

How do you stop mold from coming back?
The key to mold prevention is keeping air moisture to a minimum. Dry any condensation that may be gathering on your walls, ceiling to windowsills. Dehumidifiers can also help to remove moisture from the air. Try to keep your bathroom and kitchen door shut tightly and ensure your windows are open whilst cooking.

How can you tell the difference between mold and mildew?
So how do you know which one you’re dealing with? Mold generally looks slimy or fuzzy, tends to have a raised texture, and can come in a rainbow of colors, including deep green and black. Mildew is powdery, looks white or gray, always appears flat, and grows on surfaces.
