What Is Mold?
Mold, also known as mildew, is a fungus that grows in damp and decaying conditions. There are many species of mold in a wide range of colors, including white, green and black. Mold spreads by releasing spores that begin new colonies when they land on wet or damp surfaces. Some people experience health problems when they come into contact with mold. When cleaning moldy areas, it’s important to follow safety guidelines to protect yourself and to prevent the spread of spores.
In this guide, we’ll focus on removing mold from hard surfaces like drywall, grout and tile. It can be nearly impossible to remove mold from soft surfaces, such as fabric and leather, because the mold penetrates between the fibers. Consider disposing of such objects rather than trying to treat them for mold growth. This is especially true for black mold removal.
A crucial factor in mold removal is moisture control. Without addressing the underlying issue that causes mold, it’ll keep growing back. Once you’ve removed the mold, take some time to investigate the cause.
Mold and Your Health
Safety is crucial for mold removal. Most symptoms that mold causes are mild, but they can become more serious after repeated or prolonged exposure, or if the exposed person has a chronic respiratory condition such as chronic obstructive pulmonary disease (COPD) or asthma. When you disturb the mold, the spores can worsen these negative effects.
Common mold allergy or sensitivity symptoms include:
- Congested or runny nose
- Sneezing
- Irritated eyes
- Coughing
- Sore throat
- Headache
- Wheezing
To avoid these symptoms, ventilation and personal protection are essential. Make sure you have safety gear, such as waterproof gloves, an N95 respirator and goggles without ventilation holes. These will help prevent mold from coming into contact with your skin, lungs or eyes.
What Kills Mold?
There are several options for mold removal that you can either buy or make on your own. You can use any of the following:
- Store-Bought Mold Remover: Follow the instructions on the label.
- Chlorine Bleach: Use on outdoor surfaces, such as brick and stone, and in bathrooms. Mix 1 cup of bleach with 1 gallon of water. Never mix bleach with a product that contains ammonia because the chemical reaction causes toxic fumes.
- Hydrogen Peroxide: This usually comes in 3% to 10% solutions. Hydrogen peroxide is a more natural alternative to bleach for cleaning mold.
- Distilled White Vinegar: Vinegar is natural and gentle, and it’s suitable for cleaning household appliances like fridges or coffee makers. Use undiluted vinegar.
- Dish Soap: This works well on interior walls. Mix 1 part dish soap with 20 parts water and 10 parts bleach.
At Lowe’s, we offer a wide range of basic cleaning supplies, including indoor and outdoor mold removers, to suit any mold-removal project. Follow the use and safety instructions for each product.
How to Remove Mold From Hard Surfaces
There are several simple steps for removing mold. Once you’ve prepared your area and supplies, take your time. It’s better to be thorough than to rush the process.
How to Prevent Mold
When you’ve found the source of the moisture, address or repair the problem. This will help prevent mold from returning or fresh growth from starting.
- Set up a dehumidifier to pull excess moisture from the air. A dehumidifier won’t get rid of mold, but it’ll help prevent it.
- Use external air vents in damp rooms, such as bathrooms and laundry rooms.
- Don’t paint directly over mold, as the paint will peel, and the mold will continue to grow.
- Use mold- and mildew-resistant versions of paint and drywall.
- Avoid storing items like linens and clothing in damp areas, such as basements.
