What Happens If You Wear Moldy Clothes?

Mold is a common fungus that can readily grow on clothing, and wearing moldy garments can introduce you to a range of potential health concerns. Mold feeds on organic materials, making natural fibers like cotton, linen, silk, and wool particularly susceptible to infestation.

The presence of moisture is the primary catalyst for mold growth. When fabrics are left wet, stored in high humidity, or lack proper ventilation, they become an ideal environment for mold spores to germinate. Understanding the risks associated with wearing these affected items is important, as reactions to mold exposure vary significantly among individuals.

How Mold Affects the Body

Wearing moldy clothes directly exposes the skin and respiratory system to fungal spores, which can trigger physiological responses. The most common reaction is an allergic response, where the immune system overreacts to the presence of the foreign mold particles. Symptoms often include sneezing, a stuffy nose, watery or itchy eyes, and coughing.

Direct contact with moldy fabric can also lead to irritant reactions on the skin, known as contact dermatitis. This may manifest as a rash, redness, or itching where the garment touches the body. For individuals with pre-existing conditions like asthma, inhaling mold spores can exacerbate their symptoms, leading to wheezing, shortness of breath, or a severe asthma attack.

Some molds produce toxic compounds called mycotoxins, which can contribute to more severe health issues upon prolonged exposure. The risk of serious illness from mycotoxin exposure simply by wearing moldy clothes is low compared to inhalation in a heavily contaminated environment. However, extended or repeated exposure to mold spores can suppress the immune system and has been linked to long-term issues like chronic lung inflammation.

Recognizing Mold Infestation on Fabrics

Mold growth on fabrics is often first detected through the sense of smell, as the fungi release metabolic byproducts that create a distinct musty or earthy odor. This pervasive smell is a reliable indicator that microbial growth is occurring, even if it is not immediately visible.

Visual cues include irregular spots or patches of discoloration on the fabric. Mold can appear in various colors, most commonly black, green, or white, but also occasionally blue or red. These patches may have a fuzzy, velvety, or powdery appearance, especially in the case of mildew.

The conditions that enable mold to thrive are rooted in moisture, warmth, and poor airflow. Storing clothes in high humidity (above 65% relative humidity) or in poorly ventilated closets creates a favorable environment for spores to germinate.

Leaving damp items, such as wet towels or recently washed clothes, crumpled for extended periods dramatically increases the risk of growth. Mold can even grow on synthetic fibers if they are soiled with organic residues like dirt, sweat, or body oils, which serve as a food source. Inadequate drying or storing clothes that are not thoroughly clean can set the stage for mold to colonize any textile.

Safe Cleaning and Disposal Methods

When dealing with moldy clothing, safety precautions should be taken to avoid inhaling spores or spreading them. It is advisable to wear gloves and a respirator mask, such as an N95, when handling infested garments. The initial step is to take the item outside and gently brush off any visible, loose mold growth using a soft-bristled brush to prevent spores from becoming airborne indoors.

For cleaning, hot water washing with a heavy-duty, enzyme-containing detergent is recommended, as high temperatures help to kill the mold. Adding a sanitizing agent increases effectiveness. Options include a cup of white distilled vinegar, borax, or a phenolic disinfectant. Chlorine bleach can be used for white, natural-fiber clothing, but avoid it for colored or synthetic fabrics where it can cause fading and damage.

After washing, thorough drying is necessary, as any residual moisture can allow the fungi to regrow. Air drying the garment outdoors in direct sunlight is particularly effective, as ultraviolet rays are a natural mold killer.

Clothes that exhibit extensive damage, deep-set stains, or a persistent musty odor after multiple treatments should be discarded. Mold physically digests the organic fibers of the fabric, which can weaken the material and cause holes or tearing. If the garment is porous, heavily damaged, or cannot be washed in hot water, disposal is the safest option to prevent continued health risk and contamination.
