How To Clean Driveway Mold

Fallback On Commercial Cleaning Products

EASIEST Way to Clean Moldy Concrete Patios, Driveways, Sidewalks // Pressure Washing Concrete

If vinegar or bleach do not work, or you would prefer to move directly to a commercial solution, you should have no trouble finding effective products at your local garden center or home improvement store.

You can opt for a simple patio or deck wash-type of product that is used for general cleaning if your mold or algae problem is mild. If your hardscape has been stained from the mold or algae, you may need to opt for a mold stain remover. For example, if you just purchased a home where mold or algae has been allowed to flourish for an extended period of time on concrete, brick or paving stones, there may be stains that require a product specifically designed for mold and algae stain removal.

With most of these products, you will spray the area, allow it to work its magic for a few minutes, scrub with a deck brush or push broom, and then rinse the area with water.

Enlist A Power Washer

If the stain persists, try a pressure washer. You can buy attachments that convert your garden hose into a power washer or rent a machine from your local hardware store. If you rent a machine, step up the pressure carefully as needed, so you dont inadvertently damage the concrete. Dont forget to don safety goggles and protect windows, plants, and the like, as the water pressure can damage them.

The Mildew And Concrete Problem

Mildew is a type of mold which usually appears as a thin or fine dusting of a black, grey, or sometimes white growth. Mildew relies on three essential elements for growth moisture and food. Although your concrete is not a direct source of food, that unsightly mildew gets fed plenty of essential nutrients by the fine layer of dust that sits on the surface of your patio, path or walls. The same goes for the temperature requirements of mildew its happy to grow in any temperature you live in. And of course, concrete is also a major moisture magnet!

Outdoor mildew can grow on hard surfaces such as concrete patios or the floors of your basement. Not only can mildew ruin the appearance of your concrete and make the surface slick and slippery, it can also become a health hazard. Some people have allergies or sensitivities to mildew which can result in serious reactions, especially in people who have weak immune systems or respiratory conditions. For many reasons, if you have an issue with mildew, you want it gone, and quickly.
