  • Eye protection: When disturbing mold spores during cleaning or simply using harsh chemicals like bleach, youll want to keep your eyes protected.
  • Disposable gloves: Handling mold and moldy material is reason enough to wear gloves, but it can also protect your skin from irritation when using cleaning products.
  • Stiff-bristled brush: To effectively remove mold stains on porous or rough surfaces, you will need a brush that can scrub away mold without the bristles collapsing.
  • Sponge: On softer or smoother surfaces, a disposable sponge may be all thats needed to stop mold spots from becoming more significant problems.
  • Mold stain remover: Though not essential for actually removing mold, youll likely find a dark stain on the material that the mold was growing on and youll want a product to remove it. Plus, removing the old stains can make sure that you recognize new mold growth later.
  • Bleach: A solution of 1 cup of bleach to 1 gallon of water is enough to kill mold on surfaces, according to the CDC.

How Do You Remove Black Mold

If the mold only covers a small area, and youre not allergic to it, cleaning it off your basement wall or floor is possible. You will need to use warm soapy water and a rag or sponge that you are comfortable discarding after use. You dont want to wash and re-use that cleaning material on other surfaces.

Make sure you are using a cleaning solution that is designed for cleaning mold/mildew off of porous surfaces. Be a smart consumer: read the instructions carefully and take the recommended precautions. These are usually simple things like wearing rubber gloves, and opening windows for ventilation.

The photo above is a great example of mold that has to be scraped before it can be cleaned or sealed. This type of mold removal requires more industry-grade PPE . You also need to be trained and equipped to remove the mold and all the debris. If this is not done properly, the mold can release spores and actually spread to other areas.

How To Detect & Test Basement Mold

If youve ever had a leak in your basement, or your basement contains humid air and condensation, checking for mold may be a good idea.

Even if you cant immediately see evidence of mold, it could still be growing in places not easily visible to the naked eye.

There are a variety of ways to test for mold ranging from professional to do-it-yourself testing.

When it comes to deciding whether you want to use a do-it-yourself kit or a better off with getting a professional to test your basement, there are several important factors to take into consideration.

While very affordable, do-it-yourself tests are often considered less reliable. Most do-it-yourself tests require you to set a plate out from one to four days.

The idea is that the plate will collect mold spores and yield positive or negative tests results.

The downside to this method is that its not nearly as accurate as professional testing. In contrast, professional testing is more expensive, but is often more accurate and may do a better job of knowing how to get rid of the mold in your basement.

A good do-it-yourself home test kit for mold will range from $10 to $100 while the cost of a professional testing for mold can be anywhere from $200 to $1000 depending on the size of the space you want to test.

Can Mold Be Washed Off Walls

There really are two parts to this answer. The first part is the good news: Mold can be cleaned off of wall surfaces quite easily. A vinegar-soaked rag or spritz with a commercial mold remover will generally wipe out visible traces of mold from the wall. This might be sufficient for a quick touch-up, but it will not eliminate the larger problem that is growing inside the wall. For that, we get to the second part of the answer.

Mold cannot really just be washed off the walls or any other surfaces. To really get rid of it, you need to eliminate the water source that is encouraging growth. Without water, mold cannot survive and reproduce. In a dry environment, any small amounts that might be left behind will not be able to rehydrate to start raising additional mold colonies in your basement walls.

In short, removing the surface mold off of walls will make them more attractive. Still, it will not resolve the underlying problem: There are millions or more! of tiny little fungi actively living, eating and reproducing inside of them. They will quickly return to any finished walls since drywall is backed by paper, which is one of molds favorite foods. To keep that from happening, you will need to do more than wash the mold you need to eradicate it and eliminate the water providing nourishment. Our mold remediation experts work to eliminate any residual traces of mold from the environment so you can stop worrying about cleaning mold off the basement walls.

Common Types Of Basement Mold

How to Clean Mold Off Basement Concrete Walls

The National Institute of Environmental Health Sciences lists five different types of mold as the most common:

  • Cladosporium: Usually brown, but also black or gray, this type of mold is common in soil and organic material throughout the world. This type of mold is relatively slow-growing.
  • Penicillium: Used in the development and manufacture of the life-saving antibiotic penicillin, Penicillium is also common throughout the world and is fast-growing and usually green or white.
  • Aspergillus: This fungus lives outdoors and indoors, and most people can tolerate it without issue. However, in rare cases, it can cause an infection called Aspergillosis that can be very damaging to people with weakened immune systems or lung problems like asthma.
  • Alternaria: Fast-growing and brown, olive, or black, this mold can cause serious infections, but cases are generally rare and accompanied by an underlying condition.
  • Stachybotrys chartarum: Also known as toxic black mold, Stachybotrys chartarum is arguably the most common household mold, is black to greenish in color, fast-growing, and notorious for thriving on building materials like drywall, wood, gypsum board, and coverings like wallpaper.

For example, vinegar and baking soda are both acidic and can be used to scrub away mold and help kill the spores in its wake. Simply make a half-water, half-vinegar solution, spray on the mold, leave overnight, and come back the next day to scrub off any remaining mold. If you want to get really creative, you can also use vinegar as a disinfectant.

You can add a few drops of vinegar to a quart of water and let it sit for a couple of hours, then rinse it off with clean water. The vinegar will kill all the germs in the water, but it will also kill any bacteria that may have gotten on your hands while you were scrubbing.

Negative air pressure machines are a good way to ensure that an area is free of mold spores.

Removing Basement Mold with HEPA Vacuuming: HEPA vacuums can be used for mold removal and are often a great way to ensure that all mold spores and particles have been removed from your basement.

    Mold Removal From Fabric

    Its easier than you might think for clothes to attract mold and mildew. A forgotten load of laundry in the washing machine, the pile of clothes at the bottom of a closet, or even the armchair in a humid room can all quickly become overrun with mold. However as long as you catch the problem early, your fabrics can still be saved.

    Bleachable fabrics

    If you can apply bleach to a fabric without worrying about discoloration, do it. Thats the fastest and most effective way of getting rid of mold. Many laundry bleaches can be used on white and colorfast fabrics, although you should always check the instructions, and never use bleach on wool or silk. Simply apply a solution of one part bleach to three parts water and let it absorb into the fabric for a few minutes before laundering as usual.

    Non-bleachable fabrics

    For fabrics that cant be bleached, use white vinegar instead. Either apply white vinegar to a cotton pad and place it on top of the stain for five minutes before laundering, or briefly soak in a solution of ¼ cup vinegar to one gallon water. Rinse through to remove the vinegar and launder as normal.

    How To Remove Mold From Painted Wood

    How to get rid of mold in basement | crossxpollination

    Just because a wooden surface has been painted doesnt mean its immune to mold. Interior doors, window frames, and baseboards can all get moldy. The good news is the paint can form a protective barrier that prevents mold from getting into the wood, making cleanup faster and easier.

    Youll need:

    Paper towels


    Step 1: Use damp paper towels to wipe away the visible mold. A soft-bristled brush will help dislodge any stubborn parts.

    Step 2: Make a solution of 1 teaspoon dish soap to 2 cups water and use the spray bottle to apply it to the wood.

    Step 3: Scrub the surface gently with the soft-bristled brush to remove any remaining stains. Wipe clean with paper towels.

    Step 4: Combine one part white vinegar with one part 3 percent hydrogen peroxide in a spray bottle and spritz the surface. Do not soak the wood, just get it damp. Allow to air dry.

    Mold is rarely a big problem on painted wooden surfaces, because of the protective barrier the paint creates. Vinegar and peroxide will prevent it from returning, but make sure to address the underlying cause. Painted wood isnt molds first choice for a home, so its likely theres an issue with damp in that area.
