Mold vs. Mildew: Understanding the Differences & Their Impact on Fabric

Mold and mildew are both types of fungi that can have a major impact on how your fabrics look and how usable they are, each in their own way. While they have similar characteristics, it should be noted that they aren’t the same. As such, understanding the differences between the two is absolutely crucial for effective fabric care and maintenance.

What Are Mold and Mildew?

These types of fungi thrive best in environments that are moist for extended periods of time. That could include anywhere from a poorly ventilated garage or bathrooms, to boat upholstery and outdoor furniture. However, they can differ significantly in their appearance, growth, and impact on health and materials they grow on.

What is Mold?

For the most part, mold is much more invasive than mildew. As such, mold growth can deeply penetrate the surfaces it grows on. This is especially true in damp and dirty areas. Mold spores are airborne. That means that an infestation can start in new areas just by settling in dampness and growing unnoticed in the early stages. Depending on the type of mold and the conditions, it can appear in various forms.

What is Mildew?

On the other hand, mildew (another kind of fungus) typically presents as a white powdery or fluffy mildew growth. Generally, it stays on the surface and can usually be found on damp fabrics, moisture-prone nooks & crannies, and on items stored in poorly ventilated or conditioned locations.
Compared to mold, mildew is much easier to clean and tends to be less harmful. However, it can cause a musty odor and trigger allergies.

Differences Between Mold and Mildew

Causes of Mold and Mildew on Fabrics

Both mold and mildew require organic material to grow, which is precisely why fabrics, wood, and areas affected by water damage are perfect environments for their growth.
Here are a few of the most common reasons for mold and mildew growth on fabrics and other organic material:

• Humidity and Organic Material: Both kinds of fungi thrive in moist environments and need organic matter (dirt, debris, leaf litter, etc.) to grow. That means that fabrics that aren't properly cleaned and dried can be breeding grounds for mold and mildew.
• Lack of Air Circulation: Poorly ventilated areas greatly increase humidity and moisture levels, which is why it’s important to use an exhaust fan in areas like bathrooms, boathouses, kitchens, sheds, etc., as much as possible.

Preventing Mold and Mildew on Fabrics

Prevention costs an ounce, and mildew/mold removal can cost a pound. That said, you can save a lot of money and time by taking the following steps:

• Store Them Properly: Be sure to completely clean & dry your fabrics before you store them. Also, ensure they’re kept in a well-ventilated environment.
• Use Marine-Grade Cover Fabric: Especially when winterizing watercrafts or storing outdoor furniture for the season, choosing a fabric engineered for moisture control and breathability is a must.
• Keep Them in Humidity Controlled Environments: Dehumidifiers can be heroes in damp areas of your home. Use them to maintain lower humidity levels.
• Clean & Dry on a Regular Basis: By regularly cleaning and drying your upholstery, you can help to prevent moisture buildup on any organic matter that mildew or mold grows.
