Composite decking has quickly become popular for homeowners because of its durability and low maintenance requirements. Unlike traditional wood decking, composite decking is made from a mixture of wood and plastic fibres. This makes it resistant to rot and insect damage, which can quickly occur in wood decking. While composite is an excellent choice for those who want a low-maintenance outdoor space, it still requires some cleaning. In this ultimate guide to cleaning composite decking, we’ll cover everything you need to know about maintaining your composite decking. Including the most effective cleaning techniques and how to remove some stains and blemishes.
Before you start cleaning your composite decking, it’s essential to ensure it is adequately prepared. This includes removing debris, such as sticks or leaves, and sweeping the surface to remove dirt or grit. You should also take the time to inspect your deck for any damage or wear and tear.
Once you have prepared your composite decking, it’s time to start cleaning. There are a few different approaches you can take when it comes to cleaning composite decking. The best method for you will depend on the specific needs of your decking boards.
1. Water and soap. Water and soap are one of the simplest and most effective ways to clean your composite deck. This method is especially useful for removing dirt and grime accumulated on the surface. Mix a small amount of mild dish soap with warm water in a bucket. Now you can use a soft-bristled brush to scrub the solution onto the surface of the decking. Make sure to work in small sections, paying attention to any particularly dirty areas. Once you’ve thoroughly scrubbed the entire deck, use a hose to rinse off the soap and dirt. Then brush down with a soft dry brush.
2. Pressure washer. The most effective way to clean your composite decking is by using a pressure washer. This method is particularly useful for removing ground-in dirt that is difficult to remove with a brush and soap alone. To use a pressure washer, start by setting the pressure to the manufacturer’s recommended setting for composite decking. Then, hold the nozzle a foot away from the surface of the deck, moving it back and forth in a sweeping motion. It is essential to avoid pointing the stream directly at any one spot for too long. Once you’ve finished cleaning the decking, use a hose to rinse off any remaining dirt or soap.
3. Oxygen bleach. You may need to use a more powerful cleaning solution for tougher stains and discolouration. One option is to use oxygen bleach, a non-toxic alternative to chlorine bleach. To use oxygen bleach, mix it with water according to the instructions on the package. Then apply it to the surface of the decking using a scrubbing brush or sponge. Let the solution sit for about 10 minutes, then scrub the area with a brush and rinse it off with a hose. It is important to note that this product is only suitable on light-coloured decking and should therefore be used with caution.
4. Sanding. Sometimes, you may need to sand your composite decking to remove deep stains or scratches. Use an orbital sander with medium-grit sandpaper and sand the affected area in a circular motion. Be sure to sand evenly and avoid sanding too aggressively, as this can damage the deck’s surface. Once you’ve finished sanding, wipe the surface with a damp cloth to remove any dust. This approach can only be made on composite boards with a grooved line design. It cannot be done on decking boards with an embossed woodgrain side showing.
In addition to these cleaning methods, there are other steps you can take to keep your composite decking clean. One crucial aspect of composite deck maintenance is preventing stains from occurring in the first place. To do this, you should regularly sweep the deck to remove any loose dirt or debris. It is essential to clean up any spills or messes on the surface promptly. You should also avoid placing heavy objects on the deck, which can cause permanent damage or indentations.
Finally, it’s important to remember that composite decking is a low-maintenance option, but it still requires some care and attention. Following these guidelines and using the proper techniques can keep your composite decking looking beautiful for years.
