Composite decking is one of the most low-maintenance decks available. However, many mistakenly think that it requires no maintenance. You still need to maintain it to avoid having other problems. One of which is mold growth. While most composites are marketed as resistant to mold growth, molds and fungi can still grow on them. If this happens, how can you remove mold from your composite decking? Fortunately, there are a few easy ways to do it. Here are some of them.

Using Commercial Deck Cleaning Products

One of the easiest ways to remove mold is by using deck cleaning products specifically designed to remove moss and algae from your deck. You can find them in your local stores. The most effective ones are oxygenated deck cleaning products that contain sodium percarbonate. They often come in powder form, but liquid cleaners are also common. 

How do you use these cleaners? For many commercial mold-removing cleaners, you only need to wet the deck with it and leave it for a few minutes for the chemicals to take effect. Finally, rinse the deck with water. You can also use a power washer on the lowest possible setting. There are also products that you can apply to the deck and leave it until it dries. Of course, instructions depend on the product you’re using. 

Commercial cleaning products are among the most effective ways to remove mold from your deck. Unfortunately, they can cost more than using natural DIY means. 

Using Homemade Cleaning Solutions

Another excellent way to keep your deck clean from molds is by using homemade cleaning solutions. Not only is it cheap, but it can also be as effective as using commercial cleaning products. 

One of the most effective ways is by the use of vinegar and baking soda. vinegar contains acetic acid, which can kill over 80% of mold species. It can also prevent the further growth of molds. How do you clean a deck using vinegar? There are many ways to go about it. 

First, you will need to remove everything from your patio, including furniture and plants. Next, sweep the floor to remove debris and dirt. Then, rinse the deck with water. After the deck is rinsed, make a cleaning solution by mixing 1 cup of baking soda and 1 cup of vinegar on a bucket of water. If you want a stronger solution, you add more vinegar.

 Then, with a soft bristle brush, scrub the areas with molds by using the solution on the spot. Finally, rinse it off with water. If there are persistent spots, you can spray undiluted vinegar on it. Then, sprinkle baking soda and let it sit for a few minutes without letting it dry. Then, scrub it with the brush. 

Another effective method of removing mold on deck is by using hydrogen peroxide. But unlike vinegar, it doesn’t kill the molds. Instead, it lifts the mold from the surface and makes it easier to scrub away. To use it, apply it to the problematic areas until it foams. Then, use a soft bristle brush to scrub away any algae or moss on the area. 

Aside from using chemicals, you can also use a pressure wash to remove the molds from the deck. You won’t need to use any chemicals or DIY cleaning solutions for this one. You only need the sheer pressure of water to remove the moss and fungi on your deck. However, this method may be riskier than the previous ones. 

Doing it improperly may damage your deck. To make this work, you will need to determine how much pressure your deck can handle. Use a wide tip to minimize the damage. You may also want to remember that some manufacturers void your warranty if you use a power washer. 

How to Prevent Mold From Growing on Your Deck?

There is no way to prevent the growth of mold from your deck fully. It will eventually grow, but you can slow it down. Molds thrive on moisture, so make sure that your deck is dry. If you are having a problem keeping your deck dry, you can try using a water-resistant seal. However, most composite decks won’t need it. Having a regular cleaning schedule also helps to stave off molds. A thorough cleaning at least two times a year is necessary.
