If you want to keep a clean home, it's important that you cater to all aspects of your house. While cleaning drywall may seem like a no-brainer, it's actually critical that you take the proper steps and use the right materials when cleaning it. Exposed drywall is porous in nature and does not react well to water and certain chemical cleaners. In addition, drywall installation itself can create an enormous amount of dust that can be hazardous to your health. Luckily, if you use the right techniques and get the proper cleaning equipment, cleaning your drywall can be easy and straightforward.

Washing Down a Wall

  1. Lay a towel or drop cloth on the ground under the wall that you want to clean. This will make sure that no water or soap drips onto the ground. It will also help keep the dust off of your floor or carpet. [1]
  2. Use a duster or a vacuum with a duster attachment to remove all of the dust from your wall. If you don't have a duster or vacuum, you can use a dry rag. If you have exposed drywall, you should only dust your wall and limit the use of water and other cleaners on it due to the material's porous nature. [2]
    • Dust your walls at least once a week to maintain them.

  3. Using acidic cleaning solutions could damage the appearance of your wall. To avoid this, use simple water and a cellulose sponge. Dampen your sponge but don't fully saturate it. Apply pressure on the sponge and move from the top to the bottom of your wall. Saturate your sponge when it becomes too dry. Continue to do this until you've washed the entire wall.
    • In addition to being soft on your walls, cellulose sponges are made of bio-degradable materials that are good for the environment. [3]
  4. Pour two cups (473.17 ml) of warm water in a bucket with three drops of mild dish soap. Saturate the rag that you're using and work it into your walls stains in small circular motions.
    • Avoid using colored dish soaps because they can stain and dye your walls. [4]
  5. Use a dry rag or a microfiber cloth to remove the saturation from your rinsing. Make sure to clean up any leftover soap because it can damage them if left on the walls.

Removing Mold from Drywall

  1. Working around mold can be dangerous if you inhale it. Make sure to wear N-95 or P-100 respirators, goggles, and gloves when cleaning the mold. You can pick up these specialty respirators from hardware stores or online. [5]
    • Make sure that you wear clothes that you aren't scared to get dirty.
  2. If mold has started to form on unpainted drywall, you may have to remove and replace the moldy portions of the wall. If your drywall's structural integrity is being affected by the mold and your wall is crumbling, warped, or covered with black or bluish splotches, you will have to replace it. If there is mold on the wall but the structural integrity is not compromised, you may be able to clean it off.
    • Mold on painted drywall is much easier to remove.
  3. A diluted bleach solution can help you remove the mold from the wall. Mix the bleach and the water together in a bucket. Once the mixture is thoroughly combined, you can start to wash down the mold on your walls.
    • Wear thick rubber gloves when handling the bleach to prevent chemical burns on your hands.
  4. Dip a sponge into your bleach solution and make sure to saturate it well. Once it's wet, push it into the moldy area of your wall and make small circular scrubbing motions to remove the mold. Continue to go over the areas until they are clean.
  5. Once you're done scrubbing the mold off the wall, use a fresh sponge to rinse down your walls. Dampen the sponge enough to remove the bleach solution, but don't drench your walls in water. Once you've removed all of the bleach solution on the wall, allow it to air dry. [6]
  6. If your mold keeps coming back or is too much to clean, you may need professional help. A home inspector who specializes in mold will be able to tell you how to remedy your issue or any potential solutions that you can take up. [7]

Cleaning Drywall Dust

  1. Point a box fan so that it pushes air out of your apartment. This will remove the dust from inside of your house. Turn the fan to high and let the dust in the air escape the room. As you continue to clean the dust, keep the fan on so that the drywall dust that you sweep up can be blown out of your house. [8]
  2. Before you start disrupting the dust in the room, it's important that you empty the space of furniture. If you don't, the abrasive dust can settle on your furniture and hurt the finish on your belongings. Remove what you can out of the room and put it in another, dust-free room. Lay dropcloths or plastic tarps over furniture that's too large to move in order to protect them. [9]
  3. Gently walk a push broom around the perimeter of the room and work your way into the middle. Make sure to be gentle and avoid pushing the dust up into the air. Use long stroking motions when pushing the dust around and try to create one pile in the center of your room.
  4. A Shop Vac or wet and dry vacuum cleaner has a larger carrying capacity and can pick up more dust than a traditional household vacuum cleaner. Start by vacuuming up all the dust that you managed to gather in the center of the room. After the initial dust is cleaned, continue to go over the entirety of the floor to suck up the remainder of the drywall dust. [10]
    • Go over the floor again if you notice that your Shop Vac didn't get all the dust on the first vacuuming.
    • If you don't have a Shop Vac than you can rent one from a department store.
    • Make sure to use a HEPA filter to trap all of the drywall dust when using the Shop Vac.
