Composite decking requires low maintenance

Compared with traditional wood decking, one of the best advantages of composite decking is that it requires low maintenance and is easier to clean. However, low maintenance doesn’t mean that it’s totally maintenance-free. Generally, you should at least thoroughly clean your composite wood decking 2 times every year. Proper cleaning will help the WPC composite decking maintain its beauty and neatness, extend the life of the decking, as well as improve the slip resistance and safety of the decking.

 

The process of cleaning composite decking differs from that of cleaning wood decking. Wood plastic composite decking is a composite material made of HDPE plastic and wood fibers that will not respond well to harsh chemicals or abrasive scrubbers, so it is very important to know how to do the job correctly.

 

Our complete guide will show you how to clean your composite decking thoroughly, without causing any damage.

 

  1. Remove All Things From the Composite Decking

First, remove your outdoor furniture, pots, planters, doormats, and the barbecue. Then sweep your composite deck with a soft-bristled brush to remove loose debris, such as grass cuttings, fallen leaves, and twigs, trying to get in the gaps as much as possible.

 

If needed, use a scraper or putty knife to remove any dirt trapped between the boards. Just be careful not to scratch the surface of the composite. You can also spray the area with a hose to remove debris but use gentle pressure.

Important Notes

  2. For some specific kinds of stains, you can clean a small part of the stains as a testing ground in order to prevent too much chromatic aberration.
  3. Please stay away from chlorine bleach, no matter how you choose to clean your WPC composite decking as it can lead to color-fading of the decking boards. You can select oxygenated cleaners if needed.
  4. Use a pressure washer if any stubborn stains are still showing on your decking. But you should control the water pressure under 6 bar and clean the decking from a suitable distance.
