Mistakes Made When Cleaning Your Composite Deck

Springtime view

Are you about to clean your composite deck to get ready for your get-together? In this post, we will go over several mistakes people make when cleaning their composite decks so you won’t make the same bad decision.

Now that the summer months are getting closer and closer, that means your deck is about to get busier. Whether you’re having a cookout or a pool day at your house, your deck is going to get dirty. Not just during the summer months but year round your composite deck needs to be maintained. However, there are plenty of mistakes you could make while cleaning your composite deck that can lead to damage. In this post, we will give you a few mistakes people make when cleaning their composite decks.   

Pressure Washing

When cleaning a regular wood deck, most people use a pressure washer because it is able to get those tough stains out. However, with composite decks, the material used is softer than wood. When using a pressure washer, if you put it too close to the composite material or use too much pressure, you run the risk of damaging your deck. Moreover, a damaged deck can lead to even more problems such as chipping, sun damage, and even mold. Instead of power washing, use an ordinary garden hose to rinse down your deck. If you can only use a pressure washer, have it set at the lowest setting and keep it several feet away from the deck itself.


As stated above, if you damage your composite deck, you run the risk of mold forming on your deck. The biggest mistake that people make when trying to fight against mold is that they forget to clean the gaps between the boards. Although the gaps between each board aren’t that big, it’s still a perfect place for mold to grow. Over time, dirt and debris will begin to collect between those spaces, making it a breeding ground for mold and mildew. These gaps need to be cleaned at least once a year, depending on the climate of your area. By cleaning these hard to reach places, it will allow air to pass through the boards, helping the underside to be dry.  

Protecting Your Deck

Arguably the most crucial step to take when cleaning any deck is to apply sometime of moisture barrier to it. Humidity can be a major factor in the growth of mold or mildew on your deck, especially in climates like the Mid-Atlantic. Luckily, there are quite a number of different moisture barriers out there that will keep your composite deck protected against mold, mildew, and deck rot. When searching for a moisture barrier for a composite deck, be careful not to purchase any “waterproofing” sealants because those products can trap moisture inside the material, which can lead to more problems down the road.
