To Prevent Mold Growth in Your Home
Keep humidity levels in your home as low as you can—no higher than 50%–all day long. An air conditioner or dehumidifier will help you keep the level low. You can buy a meter to check your home's humidity at a home improvement store.
Cleaning vinegar, which contains 6% acetic acid, is the best type for killing mold. White vinegar containing 5% acidity will also work just fine. If you don't already have some at home, white vinegar can be inexpensively purchased at most grocery stores.
Use undiluted white vinegar on hard surfaces in kitchens and baths. A bleach solution also works to kill mold. Mix one cup of bleach in a gallon of water, apply to the surface and don't rinse. Mix a 50/50 solution of ammonia and water.
To kill and remove mold from a window sill, you can either scrub it with undiluted white vinegar or with a household bleach solution. It's usually worthwhile to start with the vinegar approach because vinegar is less harsh than bleach.
Pour undiluted distilled white vinegar into a spray bottle and spray the affected area generously. Let the vinegar sit for about 60 minutes before wiping the area clean with warm water and a disposable cloth.

Mold Prevention
Open doors and windows to increase the flow of fresh air. Turn on the air conditioner or ceiling fan to circulate air around your space. Ventilation prevents condensation. Water can bead up on walls and windows, then drip down into corners and collect there.
Mold spores need warmth, and moisture to germinate, grow and thrive. If the conditions in your home are warm and humid, but it is cool and dry outside, opening a window can serve to inhibit mold growth.
Why is black mould around windows bad for your health? Black mould has a technical name – 'Stachybotrys Chartarum' – and is known to impact air quality and cause problems with breathing. This can lead to long-term damage to respiratory health if the spores are inhaled and the mould is not treated.
While it is possible to use bleach to kill mold as well, experts agree that vinegar is a much better option. Unlike bleach, vinegar can effectively kill the mold at the root, which means it's less likely to return. Vinegar is also less toxic than bleach, making it a better choice for household use.
While a significant mold infestation is best handled by a professional restoration company, you have a powerful weapon against occasional mold growth in your kitchen cupboard: white vinegar. This humble household staple can kill more than 80% of mold species, including hazardous black mold.
Mold stays “dormant” in the air or on surfaces even when there's no excess moisture to help it grow. If the humidity in a room increases, mold will start growing in patches on walls, clothes, and more. So, to answer your question, dehumidifiers do NOT kill mold, but they do prevent it by reducing humidity.
Hydrogen peroxide is an antifungal, antiviral and antibacterial solution. Pour 3% concentration hydrogen peroxide into a spray bottle. Saturate the moldy surface completely and leave it to sit for ten minutes. Next, scrub the area to remove all of the mold and mold stains.
Do air purifiers help with mold? Air purifiers help capture mold spores from the air, preventing them from reproducing and spreading throughout your home. While air purifiers won't help treat active mold that's already present on surfaces, they are a great way to control the spread of airborne mold particles.
You can use baking soda on its own or in a mixture of vinegar and water for extra killing power. It's suitable for most window sill surfaces, including wood. Mix up enough water to form a thick baking soda paste and apply this to the affected area. Leave the paste to dry and then remove it with a clean, dry cloth.
Some people recommend using household products like Clorox Wipes, laundry bleach, or vinegar to kill mold. Do they really work? They can if your mold problem is fairly minor. Laundry detergent mixed with very warm water does a good job of cleaning mold off hard surfaces.
White vinegar is a mildly acidic product that cleans, deodorizes, and disinfects. It can also kill 82% of mold species, including black mold, on porous and non-porous surfaces. You can use it safely on most surfaces, and its offensive odor goes away quickly. Pour undiluted white vinegar into a spray bottle.

Ventilation helps prevent humid air from getting trapped indoors and wreaking havoc with mold growth. Good airflow can help cut back on moisture and will dry wet areas of your home more quickly.
