Mold Vs. Mildew: What’s the Difference?

It’s easy for people to mix up mold with mildew, considering both are fungi known for thriving in warm areas that have a lot of moisture. But there are some differences between the two that people should know before trying to prevent or treat either from growing. Here’s a rundown of how to tell the difference between mold vs. mildew prior to treating the problem.

What Are the Differences in Appearance Between Mold Vs. Mildew?

One of the most important ways one can tell mold from mildew is how each fungus looks. Mildew is typically white, gray or yellow and grows on the surface of moist, warm areas. Its texture is fluffy or powdery. On the other hand, mold tends to be green or black, and it usually grows underneath the surface of anything that has gotten wet. Its texture can be fuzzy or slimy.

Where Does Each Type of Fungus Grow?

Both mold and mildew can grow quickly in warm, moist places. But each type seems to have a preference when it comes to where to start growing. Mildew is often found on items that have damp surfaces, with fabric, paper and leather being some common household items that might end up with mildew after they get wet. Mildew is also sometimes found on the floors, walls or ceilings of areas with lots of humidity, such as bathrooms, kitchens or basements. While mildew can also grow on the surface of agriculture — such as potatoes or grapes — mold is most often the type of fungus found on food, such as cheese, bread or meat. Additionally, it’s not uncommon to find mold in indoor or outdoor spaces that have gotten wet, such as sheds, crawl spaces, garages and boats.

What Are the Effects of Mold Vs. Mildew?

Mold and mildew have different effects on the surfaces where they grow and the people who live in their vicinity. For example, mildew can harm the food it grows on, but it doesn’t typically leave lasting damage to other surfaces, such as tile floors or bathroom mirrors. Additionally, anyone who inhales mildew spores may start coughing, get a headache or have trouble breathing, so this fungus can present some health issues.

However, the effects of mold tend to be more serious. Mold can damage entire structures, including homes and vehicles, and it can cause long-term health problems for people. The difference in the effects of black mold vs. mildew is pretty stark, as reactions to mold can include respiratory issues, heart problems, joint pain, migraines, fatigue and depression. In addition, anyone who has a mold allergy may experience congestion, sneezing, and irritation of the eyes, throat and skin. This is why it’s important to prevent or treat mold as soon as possible.

How Hard Is It to Get Rid of Mold Vs. Mildew?

Yet another difference of mold vs. mildew is how difficult it is to get rid of each fungus. With mildew, all it typically takes is a mildew cleaner and a good scrubbing brush. However, mold is not an issue that most people should be dealing with on their own. Mold removal is best left to professionals. That being said, it is possible to prevent mold without hiring anyone for the job, since there are mold prevention tactics to try.

It’s also possible to buy bought mold and mildew prevention sprays at the store and online. In fact, Gold Eagle is a great source of such products, making it easy to prevent fungal growth after learning the basics on mold vs. mildew.
