What Is the Difference Between Mold & Mildew?

Mold and mildew can be hard to tell apart for many people. Both mold and mildew are fungi, but they are different kinds of fungi that prefer different environments in which to grow. Their colors and textures differ, and where you find them can aid you in identifying them.

Types

Mildew is actually a form of mold. There are hundreds of species of molds, which are microscopic fungi. Mildew comes in many species as well, but there are two distinct types of mildew. Powdery mildew is most often found on flowering plants, while downy mildew can be seen on agricultural plants such as grapes and potatoes.

Identification

In most cases, molds and mildew are found where it is damp and moist. Bathrooms and basements are popular spots for mildew to form, as you can find it on shower curtains, bathtubs and under sinks. Mildew can also appear on fabrics and paper. Molds also occur on foods such as fruits and breads. Both mold and mildew come from tiny spores that are in the air. Mold comes in a variety of colors, while mildew is normally white or gray.

Effects

It is impossible to rid your home or workplace of all mold spores, as they are everywhere. If they are present in large enough amounts they can pose a health risk to people who are allergic to molds or who experience respiratory problems because of them. Some molds produce toxins that can be a danger to individuals as well as their pets. Neurological illnesses can be a result of constant exposure to molds.

Prevention/Solution

Keeping molds and mildews from flourishing in your home can be a chore, but it is possible. Places where they grow, such as basements and bathtubs, must be kept as clean as possible. Since both thrive on moisture it is imperative to keep the home dry, with air conditioners and dehumidifiers having the ability to keep the environment inside the home at a level where molds and mildews can not grow. Moisture absorbing chemicals can be used in closets to protect fabrics from mildew; silica gel and activated alumina are two that work and do not harm clothes. Remove molds and mildews from clothes, paper, mattresses, tiles and other surfaces as soon as you find them, using a variety of cleaning products made for such a purpose. Never eat any food on which mold has begun to grow.

Benefits

Molds and mildew are important components in the breakdown of organic matter in nature. Mold in particular has proven to have many beneficial uses for man. Penicillin was created by Alexander Fleming and involved a species of mold known as Penicillium chrysogenum. Many drugs used to lower cholesterol are derivatives from mold, as are other drugs including one that helps people who have had organ transplants. Cheeses and other foods are produced with the help of cultured molds.
