How to Eliminate Mold

Essentially, mold thrives in damp environments. The issue of mold is also a problem of moisture. Cleaning mold without addressing the underlying dampness is an invitation for it to return. Clean and dry areas affected by water damage or standing water within 24 hours to prevent mold growth.

• Mold often appears in bathrooms (due to showers) and kitchens (due to sinks). Ensure you wipe away standing water on sinks and open bathroom windows after showering.

Call professional services if mold covers an area larger than 1 square meter. If you're dealing with severe mold growth – over 1 square meter – it's best to hire professionals for mold removal and cleanup. They have access to high-strength cleaning agents and protective gear to avoid inhaling mold spores.

Consider discarding porous and absorbent materials. Materials like drywall and ceiling tiles may need to be removed if heavily damaged by mold. Mold can penetrate tiny crevices and pores in these materials, making complete removal difficult. Cleaning is only a temporary fix; mold will return unless the affected surfaces are entirely replaced.

Avoid painting or sealing mold-infested surfaces. This is a temporary solution that doesn't address the root issue. Surfaces like walls or tiles that have been painted or sealed won't hold new paint or sealant properly; it will peel off due to the lack of a clean, stable surface.

• Ensure thorough cleaning of moldy surfaces before painting or sealing. Dry them and wait a day or two before applying any coatings.

Use protective gear during cleanup. Mold contains airborne spores, so wearing protective equipment is crucial when cleaning moldy surfaces. While most molds are harmless, some types can pose health risks. Make sure to use:

• An N-95 respirator mask, widely available at hardware stores at a reasonable cost.
• Safety goggles to protect your eyes from spore exposure.
• Gloves to shield your hands.

Try a mixture of bleach and warm water. Mix 240 ml of bleach with 4 liters of warm water. Use a medium-stiff brush dipped in the bleach solution to scrub away mold stains. Remember to dry the area thoroughly afterward, as moisture encourages mold growth.

• For hard-to-reach areas, pour the bleach solution into a spray bottle and apply it directly to the mold. Then scrub as usual.
• This solution works best in mold-prone areas like bathrooms, kitchens, and other tiled or non-porous surfaces.
• Bleach is highly effective at killing mold and its spores. Sodium hypochlorite, the active ingredient in bleach, is also a key component in commercial mold removal products.

Use vinegar. Pour undiluted white vinegar into a spray bottle. Spray it onto the moldy area, scrub with a brush, and then dry thoroughly.

• Only use vinegar on non-porous surfaces like tiles – avoid wood.
• Unlike bleach, vinegar is non-toxic and doesn’t emit strong fumes. As a weak acid, vinegar is believed to be 80% effective at killing mold, mildew, and their spores.

Use a borax solution to kill and inhibit mold growth. Mix 240 ml of borax with 4 liters of warm water. Dip a brush into the borax solution and scrub the moldy surface. Wipe away excess moisture and borax with a clean cloth.

• Use borax only on non-porous surfaces. It’s better suited for tiled bathrooms and kitchens than for wooden surfaces.
• While borax is toxic if ingested, it’s a natural cleaner, doesn’t emit toxic fumes, and contains no added chemicals. Borax effectively kills mold and prevents its regrowth.

Utilize ammonia. First, ensure the product is labeled “clear ammonia.” Then, mix one part ammonia with one part water and pour it into a spray bottle. Spray the solution onto the moldy surface and scrub clean. Wipe away any remaining ammonia.

• Never mix ammonia with bleach. Combining ammonia and bleach produces a toxic gas called chlorine gas, which is harmful if inhaled.
• For stubborn mold stains, spray ammonia onto the surface and let it sit for several hours before scrubbing.

Try baking soda as a paste or in its natural form. Baking soda is gentle – making it safe for your family – yet effective. It’s renowned as a mild household cleaner and deodorizer (it’s no surprise it’s used as a deodorant). Baking soda can be used in two primary ways:

• Mix it with water and vinegar. Combine 2 tablespoons of baking soda with 240 ml of water and stir well. Pour into a spray bottle and apply to moldy surfaces, such as bathroom tiles. Use a separate spray bottle with vinegar and spray it over the same area. (This will create a chemical reaction producing carbon dioxide). Vinegar is often paired with baking soda as it can kill many types of mold.
• Sprinkle baking soda directly onto moldy surfaces. This method is particularly effective on porous surfaces like wood or drywall. Let the sodium bicarbonate soak into the damp surface, then wipe it clean.

Use hydrogen peroxide. Purchase a 3% hydrogen peroxide solution and pour it into a spray bottle. Spray it onto the moldy surface, wait at least 10 minutes, and scrub clean. Dry the area to prevent mold from returning.

• Hydrogen peroxide is an excellent alternative to bleach and other strong-smelling, potentially toxic cleaners. It’s also effective at removing mold stains.
• Hydrogen peroxide can be used on various surfaces. It’s safe for clothes, floors, fixtures, walls, and even household appliances. However, test a small amount on a hidden area first, as hydrogen peroxide may cause discoloration on fabrics and other surfaces.

Remove mold from clothing. Use a brush to scrub off as much mold as possible. Do this outdoors to prevent mold spores from spreading indoors. Then wash the clothes (you can pre-soak them in bleach or a stain remover if desired). Dry the clothes in direct sunlight.

• If the clothing is not machine washable, take it to a dry cleaner and show them the stains. Ask if they can remove the mold.

Clean mold from leather items. Use a brush to remove as much mold as possible. Again, do this outdoors. Dip a cloth into a solution of half water and half denatured alcohol. Wipe the moldy area and let it dry completely.

• Instead of denatured alcohol, you can use leather soap.

Remove mold from books and paper. Ensure the moldy item is completely dry. If not, let it air dry in a well-ventilated area. Take it outside and use a dry cloth to remove as much mold as possible. Dip a cloth into a soapy solution (dish soap works). Wring it out and gently wipe away remaining stains. Rinse with clean water and let it dry.

• If soapy water doesn’t work, try a diluted bleach or vinegar solution.
• For books with multiple moldy pages, separate the pages to prevent sticking. Use a fan to speed up drying. To ensure pages don’t stick together, sprinkle a small amount of cornstarch between them while drying. Brush off the cornstarch once the book is dry.
