DuxxBak® Composite Decking

To ensure that your DuxxBak® Composite Decking and railing products bring you a lifetime of outdoor enjoyment, it is important that they are not only installed correctly but maintained properly. Cleaning is an important part of regular maintenance. Fortunately, our products are easy to clean! Why? Read about our material science.

One of the benefits of a composite decking product is that they are easy to clean and maintain and do not need to be replaced as often as wood decking. See below for our easy-to-follow care and cleaning instructions.

Through regular use and changing weather conditions, our products may require light cleaning to keep it looking fresh, as well as to allow Tongue & Groove boards to drain properly. We recommend that you proactively care for your deck. Even though mold and mildew do not cause damage to our deck boards, it is good practice to clean your deck on an annual basis (more or less depending on the environment) to prevent environmental debris build up. Use a power washer or jet feature on a garden hose attachment and clean in the direction of the grain to remove any unwanted environmental debris to keep your deck looking like new.

Our product is easy to clean. Most stains can be removed with a general-purpose household cleaner and/or degreaser according to manufacturer instructions. Concentrated dish soap or laundry detergent works well on most stains. Remember that fresh stains are usually easier to remove than ones that are allowed to set.

When it comes to the toughest stains, DuxxBak® Composite Decking recommends only the best to its customers, and that is why Corte*Clean is our number one recommended cleaning product. Corte*Clean is an eco-friendly product because it does not use corrosive chemicals that can harm the environment. This product is known for cleaning the toughest stains including grease, oil, mold, mildew, food, and that is just the beginning.

Periodic cleaning with a pressure washer will help keep your deck looking its best. Proper use is very important, so please follow all manufacturer instructions and use proper safety precautions when operating a power washer. The power washing unit should be set at a lower pressure setting, and use a fan tip nozzle. Spray should be consistent with the grain of the product. To prevent damage to the boards, be careful to stay a minimum of 12″ off the surface and do not let the spray sit idle too long.


Simply use a stainless steel wire brush to remove scratches. A few strokes along the grain will most likely refresh the deck board. Always test a small area to assure that the surface texture is not removed.


For oily stains such as gasoline, butter, mayonnaise, etc., use concentrated dish soap or laundry detergent along with a plastic bristled scrub brush.


Microbial stains, such as algae and black mold, do not damage our boards. For the most part, algae and black mold sit on the surface and consume pollen without degrading the board. These types of stains can be removed by the use of a pressure washer, plastic bristled scrub brush, and cleaners designed to remove mold and mildew.


It is safe to use ice removal products such as sodium chloride and calcium chloride on DuxxBak® Composite Decking products. When the ice melts after using salt, there may be a white residue that remains on the deck. This residue can be easily removed with a light cleaning or naturally with a rain shower.

Do not use a metal shovel on Green Bay Decking products. Instead, use a plastic shovel to remove any snow to prevent potential damage to the product.
