In turn, this will cause more problems in the future. While composites are resistant to issues such as mould growth and warping, it can happen if composite decking are neglected. When the composites begin to deteriorate in quality due to no maintenance, many unknowing homeowners will feel that they got scammed.

The good news is, being low-maintenance means you don’t have to put a lot of effort into cleaning and maintaining your composite decking. As long as you do it regularly, and whenever possible, you’ll be able to extend the life of your decking and keep it at its best quality.

Despite being resistant to moisture, composite decking can become slippery when wet.

Unlike wood, there’s no chance of moulds due to the moisture content of the boards. However, when you have piles of dirt, grass, and pollen lying around on your decking, they can become breeding grounds for fungi. To combat this, you’ll want to sweep your decking with a broom.

While most composites are scratch-resistant, it’s better to use soft, non-abrasive cleaning tools to avoid any potential damage. If a quick sweep can’t do the trick, you may need to wash it down with water.

Of course, aside from a simple sweep and rinse, you’ll have to do a thorough washing. Many composite decking experts recommend scheduling a deep clean once every six months. For this, you will need a soft-bristled brush, a garden hose or pressure water at minimal settings, and a cleaning solution of your choice.

You can either use a homemade concoction or a commercial product. Either way, you’ll want to rinse your decking, scrub it with your choice of cleaning solution, and rinse it with water.

During the winter, you’ll also have to remove any ice, snow, or water pooling on your decking. However, be careful not to use any sharp objects, such as shovels and rakes. You’ll also want to avoid abrasive means of removing snow, as it can scratch your decking.

While composites are low-maintenance, you still want to put some effort into maintaining them. Fortunately, it’s not as hard as you think. If you have instructions given to you, it’s best to follow them as well.
