How Do I Clean Mildew on Concrete Floors? : Bathroom Cleaning & More

The white powder that builds on concrete walls and floors is a soluble salt called efflorescence and is a result of water that has seeped through concrete and evaporated. A continuing build-up of efflorescence may be an indication that you need to waterproof your basement walls.

Removing Efflorescence from Concrete

The easiest way to remove efflorescence from basement concrete is to use a stiff scrub brush. Scrub the white powder to loosen it from the concrete floor. Follow by wiping the area with a wet sponge or mop, making sure to wring excess water before wiping the powder away.

Can You Use Bleach To Remove Mold From A Patio

The bleach solution is powerful in getting rid of surface stains, algae on the paver patio, mold, and concrete.

Before you begin to use this bleaching solution, you need to make sure that no adjacent grass and plants may get affected by the bleaching solution.

It is important to note that this bleaching solution can cause dizziness if inhaled and irritate your skin. Therefore, it is crucial to put on protective gear.

To use this bleaching solution method, follow this step-by-step guide:

  • Make a mixture of a gallon of warm water and a cup of bleach.
  • Put this mixture or solution into a clean spray bottle.
  • Spray the mixture directly on the mold.
  • Leave it to stay there for about 15 minutes.
  • Use a rigid bristle broom or deck brush to scrub the mold in a backward and forth motion thoroughly.
  • Rinse the solution or mixture and remove dirt debris using a garden hose.
  • Using a clean, dry towel or cloth, dry out any remaining water.
  • How To Clean Mold Off A Concrete Floor

    First, moisten the concrete floor with water before cleaning off the mold. Eliminating mold from a little damp floor will lessen the number of mold spores released into the air during removal. Use the correct amount of bleach, vinegar, or mold removal detergent and scrub the mold off entirely until it disappears. Finally, rinse the area clean and leave it to dry.

    Preventing Future Mold Growth

    You should seal the concrete with a good-quality acrylic sealer designed for exterior use. Let the concrete dry at least 2 or 3 days in rain-free, sunny conditions before sealing. I recommend using a low-solids solvent-based sealer to allow for better breathability, especially considering the warm, humid exposure conditions.

    Will Vinegar Remove Algae From Concrete

    Updated Learning: Remove Mildew From Concrete

    Yes, cleaning concrete with vinegar will remove algae from concrete. Vinegar does remove algae from concrete, similar to how it removes mold from concrete. Algae that comes into contact with vinegar dies just like mold.

    You can pour the vinegar directly onto the concrete you wish to clean, or you can pour a mixture of water and vinegar onto the concrete, scrub, and repeat as many times as necessary until all of the algae is removed.

    Remember that vinegar can only be used for a short time on finished surfaces. Not only does it kill algae, but it eats away at polished cement if you leave it on the cement for too long.

    Vinegar can be used for longer periods on unfinished cement to remove algae, and it serves as an excellent cleaning agent. Vinegar is a natural and safe alternative to cleaning concrete with harsh chemicals. In the case of algae and mold, it does a better job than bleach, and it is better in the long term for killing these infestations.

    Oftentimes, vinegar can be found in your home or garage. Be sure to use distilled white vinegar to clean algae from your concrete. You can also use cleaning vinegar.

    Should You Paint Over Mold On Concrete

    Painting over mold is never a good idea on any surface. You will spread mold spores while introducing more moisture into the colony, providing further growth. It will look as if it was covered for a few days, and afterward, it will return to an area bigger than before it was painted. Remediation is the correct way to get rid of mold on concrete.

    I Have A Major Moisture Issue Along One Wall In Basement Particularly Behind Furnace Duct

    The white, fluffy substance is efflorescence and the black spotting on the wall is mold growth. Efflorescence occurs when moisture moves through the concrete and deposits minerals/salts on the surface. In a basement, this can be a complex issue. First, I recommend looking at your downspouts and ensure they are moving the water far away from your home. Your goal is to reduce the moisture load in the soil near your home.

    If this doesnt solve the problem, youll likely need a sump pump and possibly an interior footing drain. While expensive, they are often the only way to completely solve the problem. In most cases this will involved removing the wall in the problem area so the footing drain can be installed at the very edge of the concrete slab.

    Enlist A Power Washer

    If the stain persists, try a pressure washer. You can buy attachments that convert your garden hose into a power washer or rent a machine from your local hardware store. If you rent a machine, step up the pressure carefully as needed, so you dont inadvertently damage the concrete. Dont forget to don safety goggles and protect windows, plants, and the like, as the water pressure can damage them.

    Yes, this looks like light mold growth. While this may be aesthetically unpleasant, its not likely affecting the indoor air quality. Concrete can be surprisingly porous, depending on how it cured. This porosity allows water to penetrate and can lead to mold growth. Prevention is best achieved by treating the concrete with a penetrating sealer. Note this should be done relatively soon, as the concrete loses its ability to absorb the sealant over time.

    How To Remove Mold And Mildew From Concrete

    What is mold?

    Mold is a type of fungus. The small organisms can be black, white, orange, green, or purple and live almost anywhere indoors and outside. Mold thrives on moisture and reproduces through lightweight spores that travel through the air. Youre exposed to mold every day. Theyre usually harmless in small amounts. But when they land on a damp spot in your home , they can start to grow. They release spores that you might breathe in. If you’re sensitive to mold and inhale a lot of spores, it could make you sick.

    How to remove mold and mildew from concrete

    The first method is to use household bleach. Mix one cup of bleach to 1 gallon of water. It can then be sprayed onto the concrete and scrubbed. Most of the mold should be removed through this method.

    A less aggressive method is to mix 1 cup of vinegar with 2/3 cups of water in a spray bottle. In order to treat a larger surface double, triple, or quadruple the ratio and use a low pressure sprayer. Spray the mixture directly on the mold and mildew and wait 30 minutes. After 30 minutes, spray more and scrub gently with a sponge. You should begin to see the mold and mildew scrub off. If there is still additional mold and mildew, spray with the vinegar/water mixture and wait another 30 minutes before scrubbing and wiping away the mold and mildew.

    Once the mold and mildew has been reomved from the concrete if there are any grease stains, use the Micro-Degreaser 1100 to remove them.
