What Is Lipstick Mold Fungus and How to Remove It
Understand the common pinkish-red fungus found on wood. This guide clarifies its nature as a surface allergen and its low impact on structural integrity.
Lipstick mold is a distinct fungus known for its color, which gives it its name. Initially appearing as a white, fluffy growth, it transitions to a pink or reddish hue as it matures. This mold is scientifically identified as Sporendonema purpurascens. It is often found on decaying wood and other organic materials, where it feeds on available nutrients.
Identifying Lipstick Mold
Visually identifying lipstick mold involves observing its color and texture progression. The fungus begins as a white, cottony mass, which can be mistaken for other common molds in its early stages. Over time, this growth develops into a vibrant pink or red color, often with a powdery or velvety texture that resembles smeared lipstick.
This particular mold is most frequently found on damp or decaying wood, sawdust, and lumber. It is a wood-associated fungus, a detail that helps differentiate it from other molds with a similar pinkish hue. For instance, the common pink mold often seen in bathrooms on grout or shower curtains is typically Serratia marcescens, a bacterium, not a fungus primarily found on wood.
Potential Health and Structural Concerns
While its appearance can be alarming, lipstick mold is not considered highly toxic compared to some other well-known molds. However, like any mold, it can act as an allergen and irritant for sensitive individuals. Exposure to its spores may trigger allergic reactions, respiratory irritation, sneezing, or skin rashes.
From a structural perspective, lipstick mold is largely a surface-level issue. It feeds on the simple sugars present in the wood but does not cause the significant, deep-seated decay associated with true wood-rot fungi. Although unsightly, it does not compromise the structural integrity of a building; however, its presence indicates a moisture problem that should be addressed.
How to Remove Lipstick Mold
Before beginning the removal process, it is important to use personal protective equipment (PPE). Wearing an N95 mask, safety goggles, and gloves will help prevent the inhalation of spores and avoid skin irritation.
The affected area should be isolated to prevent spores from spreading to other parts of the home. This can be done by closing doors or using plastic sheeting. Clean the surface using a scrub brush with a simple solution of soap or detergent and water. After scrubbing the mold away, dry the area completely to remove the moisture that allowed the mold to grow.
For small-scale infestations, this DIY approach is often sufficient. If the mold covers a large area, such as more than 10 square feet, is found within the HVAC system, or returns after a thorough cleaning, it is advisable to contact a professional mold remediation service. Professionals have the specialized equipment to handle extensive or persistent mold problems.
Preventing Future Growth
The most effective way to prevent lipstick mold from returning is to address the underlying moisture problem that allows it to thrive. Controlling humidity is a primary step. Using dehumidifiers to maintain indoor humidity levels below 50% can create an environment where mold cannot easily grow.
Ensuring adequate ventilation throughout the property is also beneficial. This can be achieved by using exhaust fans in high-moisture areas like kitchens and bathrooms and promoting good airflow in other living spaces.
Promptly repair any leaks from pipes, roofs, or windows to eliminate a critical source of moisture for mold. For those storing lumber or firewood, keeping it in a dry, well-ventilated location away from the home’s foundation will help prevent the mold from establishing itself on these materials and potentially spreading.
