How To Clean Mold Off Walls (Incl. Helpful Tips)

If you notice white or black spots on your wall, that may be mold growth.

Mold can thrive on various surfaces like painted walls, bathroom tiles and grout, and drywall.

They don’t only look appalling, but they can also be dangerous.

They can cause skin, eye, and throat irritation.

People with asthma and allergy may experience worse.

Thus, you need to take action as soon as you notice mold growing inside your home.

If not, their colony may expand and cause more harm and damage.

If you’re up to take the task of cleaning mold growth, read our step-by-step guide below.

How To Remove Mold With Bleach

Bleach is an effective chemical to kill mold.

However, it only works on non-porous surfaces.

Using bleach to treat mold on porous materials like wood and drywall will only remove the surface mold.

Due to the inability of bleach to penetrate pores, the mold roots beneath the surface won’t be affected.

Hence, if you plan to use this method, make sure that you’re fighting mold on non-porous surfaces like tiles and painted walls.

  1. Make sure that you’re wearing proper protective gear and your work area has proper ventilation.
  2. Vacuum the moldy surface to collect loose mold spores and prevent them from dispersing.
  3. In a spray bottle, create a solution with bleach and water in the ratio of 1:3.
  4. Spray the bleach solution onto the wall and leave the bleach on your wall for a few minutes.
  5. Scrub the affected area with a brush to eliminate the mold, gunk, and stains.
  6. Repeat the process if there are hard-to-remove stains.
  7. Wipe the area with a damp towel.
  8. Dry your wall with another dry towel.

How To Clean Mold Off Walls Without Bleach

If you don’t have bleach at hand, there are other methods you can utilize to clean mold off your walls.

It’s probably a good thing that you don’t have bleach because it can be harmful and corrosive.

It could do more damage to your home surfaces and put your health at risk.

It’s better if you use safer alternatives such as vinegar.

White vinegar is green and non-toxic.

But, it is tough on stains and fungi due to its cleaning and anti-fungal properties.

How To Clean Mold Off Walls With Vinegar

Here’s how you can treat your moldy walls with vinegar.

  1. As usual, safety first: wear protective goggles, gloves, and face mask.
  2. Vacuum the affected area and its surroundings to suck up spores and dust.
  3. Place pure white vinegar in a spray bottle.
  4. Spritz the vinegar on the molds on your walls and let it sit for an hour.
  5. Rinse the area with a clean, damp towel.
  6. Allow the area to dry completely. Use a dry towel and ventilation to speed up the drying process.

How To Remove Mold From Painted Walls

Mold can occur on painted surfaces such as your walls.

When that happens, you need to use a technique that won’t damage the paint or wallpaper.

Distilled white vinegar works well in killing off mold without affecting the paint.

Aside from vinegar, you can use dishwashing liquid.

  1. Keep yourself protected while cleaning by wearing a pair of goggles, gloves, and a face mask.
  2. Collect loose spores and dust using a vacuum cleaner with a HEPA filter.
  3. Mix dish soap and water in a spray bottle.
  4. Spray generously on your moldy painted walls.
  5. Scrub gently using a soft-bristled brush or non-abrasive sponge to avoid scratching the paint.
  6. Rinse the area using a clean, damp towel and then dry with another towel.
  7. If the area needs repainting, use a mold-killing primer and mold-resistant paint to prevent mold growth.

How To Remove Mold From Drywall

Your walls and ceilings are composed of drywall.

A drywall is a porous material that is good at absorbing moisture.

That’s why mold likes them and thrives on your drywall.

When mold gets the best of them, the fungi could weaken their durability and damage them.

In the worst case, you may need to remove your drywall and install a new one.

  1. Wear rubber gloves, a face mask, and eye protection.
  2. Use a vacuum with a HEPA filter to reduce the spores floating in the air.
  3. Check the extent of the damage.
  4. If you require new drywall, remove your existing drywall. And then, treat the surface with vinegar to kill the mold spores underneath and prevent regrowth. Finally, install new drywall.
  5. If you only need cleaning, mix 1 part vinegar, 1 part water, and 2 parts baking soda in a spray container.
  6. Spray the solution onto your drywall and let the liquid soak your wall for a few minutes.
  7. Scrub the area with a medium-bristled brush to remove stains and discoloration.
  8. Rinse well and dry the surface.

Removing mold buildup is not a difficult task.

At the least, you will only need common household items such as vinegar, bleach, and a brush.

Also, it will only take a few minutes to get the job done.

So, get your cleaning tools and products now to clean mold off your walls.
