What Causes Mold in the Closet, Hunker

What Causes Mold in the Closet?

Mold can appear in many colors, from white to black with numerous shades in between. It can also appear in different consistencies, from velvet to slimy, depending on how deeply the colony resides within its affected household surface. If you notice mold growing in your closet, the problem could be caused by several factors.

Moldy Fabrics

Fabrics such as clothes present a prime breeding ground for mold. Cotton provides «food» (or nutrients) for mold, and the absorbent nature of fabrics allows them to retain moisture. This combination of moisture and nutrients causes clothing to attract mildew (an early stage of mold growth). If you have moldy clothes hanging in your closet, the spores can easily spread and settle in new locations, such as on the carpet and on the walls of the closet. Always inspect clothes before putting them away, and never hang wet or damp clothing in your closet.

Humidity

In seasons of high humidity, closets can prove conducive to mold growth, according to North Dakota State University professor Kenneth Hellevang. Closets along exterior walls have the highest risk, as excess water vapor accumulates in the dark isolated location. You can improve the air circulation to the closet by leaving the door open during periods of high humidity, and you can keep the humidity under control using a dehumidifier.

Water Damage

Moisture must exist in some form for mold to grow. If you can rule out humidity, inspect your closet for another source of moisture. Perhaps you have a leak in the ceiling resulting from a recent rainstorm. If the moisture appears to come from within the walls, contact a mold remediator immediately. This usually points to an internal plumbing problem, and you may have a larger mold colony growing inside the wall.

Attic Mold

Mold grows from spores and can spread rapidly to new locations. If you cannot identify the source of your closet mold, it may have originated in a completely different location, such as above the ceiling. Mold seeps through wall boards and ceiling tiles, settling in new locations such as closets. Find exactly where the colony exists in your closet (for instance, you may notice dark patches on the ceiling), and determine whether you can access the other side (such as the attic) to find the root cause of the mold. Always wear a breathing mask when inspecting for mold.

How to Remove Mold in the Closet

Dark, damp and humid closets can be breeding grounds for mold.

Mold frequently collects in carpeting or drywall at the back of closets, and can spread to clothing or packed items. Use Concrobium to eliminate mold on interior walls, flooring and clothing.

Concrobium Mold Control can be used on both hard and fabric surfaces. Start by removing and inspecting all closet items. Clothes and items that are mold-infested should be bagged and discarded. Remaining building materials/surfaces and items should be treated as follows:

  1. Spray the affected area with Concrobium Mold Control.
  2. Allow to dry completely. As it dries, the solution forms a film that crushes and eliminates the underlying mold spores.
  3. Clean the surface with a Concrobium-dampened cloth or brush. If mold residue remains, paint the surface or take other cosmetic steps as required. Try our Concrobium Mold Stain Eraser for tough and embedded mold staining.
  4. As a final step, reapply Concrobium Mold Control to help resist re-infestation.

Tip: Address the moisture source to solve the mold issue; dry damp clothing and equipment prior to storage; fix any leaks behind walls and ensure relative humidity in the area is no higher than 50%.

Anyone who has dealt with mold knows that it’s smelly, hard to remove, and can cause headaches — literally and figuratively. You don’t have to accept its presence in your home! Mold exposure can lead to health concerns, from rashes to respiratory ailments, so eliminating mold safely and effectively is important. If you want to get rid of mold without harsh chemicals, read on.

«If you find mold in your home, don’t panic,» explains Dr. Lauren Tessier, a Naturopathic Physician in Vermont. «Stressing over things just activates our flight or fight system, which can make us feel worse. Simply make a plan and get to work.»

If you’ve found mold in your home, you can use environmentally and budget-friendly DIY cleaning methods. «The reality is, you will find a solution that will work for you,» says Tessier.

What Is Mold Exposure?

Molds are fungi that grow on materials in homes and buildings. You may hear it referred to as «black mold» or «toxic mold.» but there are many types of mold, and they can be almost any color. Molds give off a musty odor and often look like a stain on surfaces such as wood, fabric, carpet, and drywall. [1]

Mold thrives in damp and moist environments. It reproduces by releasing tiny spores into the air that people and pets inhale. Cladosporium, Penicillium, Chaetomium, and Aspergillus are common molds you may encounter indoors. Many people are worried about black mold (usually Stachybotrys chartarum); you can remove it as you do other species.

Like all forms of fungus, molds are living organisms that grow and reproduce. In the right conditions (warm, moist), most molds go through a four-stage life cycle: spore, germ, hypha, and mature mycelium. [2]

Mature molds produce microscopic spores and release them into the air, similar to plant seeds. The spores land on a surface where they grow (germ stage). Hyphae are long, thin branching structures. These hyphae join together to form a mycelium, which is a name for multiple hyphae together. As the mold mycelium grows and expands, it eventually «fruits,» producing new spores and releasing them into the air to repeat the mold life cycle. [2]

Mold thrives if your home has water damage from rain, flooding, or a water leak. The best way to break the mold life cycle and prevent exposure involves thoroughly cleaning all surfaces in the environment that have mold. After that, remove excess humidity in the air to prevent it from taking hold again.

How Does Mold Affect Health?

When you inhale mold — usually the spores — or get it on your skin, this is considered mold exposure. The delicate mucous membranes of the nose, mouth, and ears are particularly sensitive to mold exposure. People who live in homes with mold and damp conditions are more likely to experience health issues from mold exposure.

Some people call it «toxic mold» because of the health issues people may experience after exposure. Many molds produce mycotoxins, naturally-occurring toxins produced by mold spores that pose a serious health risk to people. [3, 4, 5]

The most common symptoms of mold exposure include:

  • Chronic coughing
  • Congestion
  • Eye, nose, and throat irritation
  • Skin rash
  • Itchy skin
  • Eye irritation
  • Worsening allergies and asthma
  • Brain fog

Infants, children, the elderly, and those with existing health conditions such as asthma are at higher risk of developing health issues from mold exposure. [4] Symptoms can occur immediately or show up later. [3] Chronic exposure to mycotoxins can wear down your immune system. They may cause abdominal pain, fever, headache, vomiting, and more. [6] All mold has the potential to cause allergic reactions, leading to dry, scaly skin, watery eyes, and a runny or stuffy nose.

Take mold seriously. It’s not only harmful to your home, but also to your health.

Eco-Friendly Ways to Get Rid of Mold

Since we spend so much of our time at home, we want to make sure our homes are healthy environments. If you know you have mold inside of your home, it’s important to get it cleared away as soon as possible.

Before beginning any mold remediation, take steps to ensure that you don’t expose your skin or mucous membranes to mold and mycotoxins during the cleaning process. Look for these items: [7]

  • An adequate breathing mask or respiratory protective device (e.g., N95 mask)
  • Safety goggles
  • Rubber gloves
  • Old rags and a scrub brush

An N95 mask is designed for a close facial fit that provides efficient filtration of airborne particles such as mold spores. You can purchase these at most home improvement stores.

Don’t pull out harmful chemicals like bleach to get rid of mold. Plenty of natural remedies work. Here are some of the most effective and safest ways to remove mold from surfaces in a healthy way.

These recipes are in quantities you would use for indoor cleaning. If you have outdoor surfaces to clean mold off of, you may require larger quantities for these recipes.

Tea Tree Oil

Of all the natural solutions, tea tree oil (Melaleuca alternifolia) may be the most effective. [8] A natural fungicide, even small amounts of tea tree oil can kill stop spores on contact.

Tea tree oil has many uses and is environmentally friendly, which makes it a great choice.

How to Use: A little goes a long way. Mix one teaspoon of tea tree oil with one cup of water in a spray bottle. Be sure to wear gloves, as undiluted tea tree oil may irritate your skin. Mist the affected area with your solution and wipe away.

Vinegar

Vinegar (acetic acid) has an antimicrobial effect on fungi and can eliminate many mold species. [8] Regular white vinegar — the kind you can cook with — contains 5 percent acetic acid. To get rid of mold, buy cleaning vinegar with at least 6 percent acetic acid. You can get it at most home improvement stores. This extra 1 percent of acidity makes the solution much more effective.

Vinegar can also stop viruses and bacteria in their tracks, so cleaning your home with it can help you and your family stay healthy! [9]

How to Use: Pour white distilled, undiluted vinegar into a spray bottle. Spray the vinegar directly onto the moldy surface and let it sit for an hour. Use a scrub brush to loosen any mold and wipe the area clean with warm water. Any smell from the vinegar should clear within a couple of hours.

Hydrogen Peroxide

Hydrogen peroxide is a powerhouse cleanser. With its antiviral, antibacterial, and antifungal properties, it is lethal to most types of mold — but safe for people. [10, 11]

As a non-toxic cleanser, you can use hydrogen peroxide around pets, children, and anyone experiencing respiratory discomfort because it’s not a lung irritant. You can use it on any surface, including walls, sinks, countertops, and other hard surfaces.

How to Use: Saturate any moldy surface with generous amounts of 3 percent hydrogen peroxide and let it sit for 10 minutes, or wait for the peroxide to stop bubbling. Scrub the area to remove all mold remnants and stains, and wipe the surface to remove any residual mold and spores. You may want to repeat this step after your initial clean-up to ensure complete mold removal.

Baking Soda

Baking soda (sodium bicarbonate) is a white mineral powder that you can safely use to remove mold on most surfaces. In addition to eliminating mold, it will help absorb moisture to prevent further mold growth. [12] Never mix baking soda with vinegar, or you might get a dangerous chemical reaction.

How to use: Add one-quarter tablespoon baking soda to a standard spray bottle. Mix with water and shake until the powder has dissolved. Generously spray the moldy area with the solution. Use a scrub brush to get mold off of the surface. You may want to repeat this process the following day.

If you have mold in your grout, mix a 50 percent water, 50 percent baking soda paste solution. Place the paste on the grout and let it sit for 10 minutes. Scrub and rinse thoroughly to remove all mold. Wipe dry.

How to Prevent Mold

Mold can grow on anything that holds moisture. It can sometimes be difficult — but not impossible — to avoid. Keeping your home dry and controlling humidity is the key to a mold-free home. Here are some tips.

Dehumidifiers

Experts recommend keeping the humidity in your home between 30 to 50 percent to prevent mold growth. [13] A dehumidifier can reduce the amount of moisture in the air, which makes your home less mold-friendly, particularly if you live in a high-humidity climate.

Keep in mind that dehumidifiers can help prevent mold growth and spread, but they can’t remove spores that are already there.

Keep Your House Ventilated

Keep your home well-ventilated, ensuring that air moves freely throughout the home; this deters mold. Use ventilation fans in bathrooms when showering, and exhaust fans in the kitchen when cooking. Clothes dryers should be properly ventilated to the outside, too. [13]

Other things you can do to prevent mold growth include:

  • Seal bathtubs and sinks with caulking to prevent water from leaking and pooling.
  • Re-grout tiles to help deprive any remaining mold of oxygen and prevent growth.
  • Remove excess water left on shower doors and walls with a bathroom squeegee, available at home improvement stores.
  • Check window sills, walls, the roof, and the foundation regularly for condensation, moisture, or leaks.
  • If you find any leaks or experience a flood, dry the area within 48 hours to prevent mold growth. Use fans to speed drying.
  • Ensure good air circulation throughout the home. Open windows when possible.

Points to Remember

If you want to know how to get rid of mold, there are simple, natural remedies that can work. Tea tree oil, hydrogen peroxide, baking soda, and vinegar are four easy-to-use, healthy choices for mold remediation.

Mold thrives in moist and damp environments, and exposure to this fungal species can cause health issues — particularly with your respiratory system. Cladosporium, Penicillium, Chaetomium, and Aspergillus, as well as black mold (Stachybotrys chartarum) are common indoor molds. The most important measures for mold prevention are controlling moisture and keeping your home dry.

Generally speaking, mold exposure symptoms clear up once it is removed — then you will likely feel better and have a healthy home once again. If your living space has significant water damage and the drywall has been wet for more than 48 hours, it may be too mold-damaged to simply clean the surface. Porous materials like drywall can harbor mold below the surface. In these cases, you should seek a professional mold remediation company.

If you continue to experience long-term health effects from mold exposure, talk with your healthcare provider.

How Can I Get Rid of Mold Growing in My Closet?

Things You’ll Need

Closets are an excellent place for mold to start growing. While this may be good news for the mold, it’s not so great for the homeowner to deal with. Closets are typically poorly ventilated, kept dark and can have moisture issues, particularly if they are connected to an outside wall. These are conditions in which mold thrives. To get rid of the mold growing in your closet, clean the area thoroughly.

Step 1

Open any windows that are near the closet to help ventilate the room during the mold removal. Lay a tarp down on your closet floor to protect it from the cleaning solutions.

Step 2

Wear rubber gloves and a protective face mask while cleaning the mold in the closet. The face mask is particularly important since you will be cleaning up the mold in the confined space of the closet.

Step 3

Add a few cups of water to a spray bottle. Spray all the mold-covered areas in the closet with the water to keep spores from spreading in the air.

Step 4

Fill a bucket with warm water, adding several drops of mild dishwashing soap.

Step 5

Scrub down the mold in the closet using the detergent cleaning solution and a stiff brush. Remove all mold with this cleaning method.

Step 6

Spray down the closet again using the spray bottle filled with water. This should rinse away the detergent solution.

Step 7

Use a large towel to dry all the surfaces in the closet that you scrubbed. Keep the door or doors open until the surfaces are completely dry.

Get Rid of Mold/Mildew Problem in Closets

Mildew is a thin, often whitish to bluish-green growth produced by molds on many surfaces. Molds are fungi that grow in the form of multi-cellular filaments. Although molds are always present in the air, those that cause mildew only need moisture and a certain temperature in order to grow.

Closet mildew causes more than foul odor. In addition to an unpleasant musty odor, molds and mildew cause considerable damage if permitted to grow. Any dark area is prone to mildew growth. Mold and mildew can grow on closet walls and your clothing. Mold and mildew are health hazards to everyone exposed.

Preventing it is much easier than dealing with mold and mildew removal and is the best mildew policy. If things are kept clean, well-ventilated and dry, your chances of having mildew are greatly lessened.

Prevention:

1. Keep Things Clean: Make sure your clothing, linens and shoes are completely dry before placing them in the closet. Items such as thick towels, comforters, heavy jackets, shoes and boots can take a while to dry after getting wet. Putting away wet garments and shoes is the perfect place for mold and mildew growth to begin.

2. No Excess Moisture: The first step in mildew control is to try to control the dampness inside the home. Cooking, laundering and bathing, without adequate ventilation, add three gallons of water to the air every day. Dampness in any structure is caused by condensation of moisture from humid air onto cooler surfaces. Leave the closet door open for ventilation and allow the dehumidifier to remove any excess moisture from the air. In bathrooms, leave the door to the linen closet open whenever possible to allow light in and air to circulate.

3. Dry the air (mechanically ):

• Cool air holds less moisture than warm air. Properly-installed air-conditioning systems remove moisture from the air of the living space by taking up warm air, cooling it (removing the moisture) and circulating cool, dry air back into the room.

• If your closet is in a room that is prone to dampness buy a dehumidifier for either the inside of the closet or place it close to the closet. Leave the closet door open for ventilation and allow the dehumidifier to remove any excess moisture from the air. In bathrooms, leave the door to the linen closet open whenever possible to allow light in and air to circulate.

4. Dry the air (chemically):

• Use baking soda for closet mildew. If closet mildew is clinging to the walls, mix ½ cup baking soda with a gallon of warm water. Apply the mixture to the affected area of wall or ceiling.

• Use other products that absorb moisture from the air such as small silica gel sachets. Be sure to keep silica gel out of the reach of children and pets.

• Another moisture-absorbing chemical is anhydrous calcium chloride. It is available in small, white granules that hold twice their weight of water. Because it liquefies as it absorbs moisture, do not let this chemical touch clothing or household textiles; it can make holes in them.

• You can also keep an open box of chalk, charcoal briquettes or cat litter to absorb the extra moisture in the air which can lead to mold and mildew growth.

5. Install a light in the closet: A light can provide enough heat to dry the air enough to inhibit any mold and mildew growth. Do not use compact fluorescent bulbs in the light because they do not generate heat and will not help to prevent a mold problem.

Removal:

The mildew spots have to be removed immediately. Brush off surface growth outdoors to prevent scattering the spores in the home. Wash mildew-stained articles once with soap and water, rinse them well and dry them in the sun.

Use a cleaning solution that will kill the mold and mildew in your closet. The cleaning solution consists of 1 cup of chlorine bleach for every gallon of warm water. Wait several minutes before you rinse the bleach solution from your closet (the solution will get into the wall and kill the mold and mildew).

To remove mildew stains sponge rugs and carpets with thick, dry soap or detergents suds and wipe clean with a damp cloth, or clean them with an electric shampoo machine. But if the pad under the carpet is wet, the entire carpet and pad will have to be removed. This is necessary so the sub-floor can dry, which in many cases prevents it from buckling.

People can have negative reactions to mold. Use mask that will shield you from fumes and gloves that will protect your skin from chemicals.

You should know that some moldy surfaces cannot be cleaned. Moldy drywall will have to be cut out and replaced. It is a good idea that wood surfaces affected to be sand to ensure the mold is completely removed.

Mold spores can be breathed in easily and can cause a lot of problems: breathing; congestion; asthma attacks; coughing and more. Mold and mildew are in areas that do not get a lot of sun and are colder, so they will be the moist places in your home. Closets are especially vulnerable to mold.

Mold removal is essential to ensuring a safe home and can be done quickly and easily.
