The most appealing feature of composite decking is its low-maintenance nature. However, it is not entirely maintenance-free. Composite wood decking does not require staining, sealing, or painting. Still, you should wash it with soap and water at least once a year or every six months to get rid of dirt, mold, and other debris and keep it clean and in good shape.

The main reason composite decking doesn’t need much upkeep is because of the materials it’s made of and the way it was designed.
Composite decking is made from reclaimed plastic and wood fibers, not real wood. When these two materials are put together, they make a new kind of board that looks like wood but is more durable than plastic. Some goods from companies like Trex and COOWIN have an extra layer of protection on the outside of the core material. That makes it more resistant to scratches, stains, and UV rays.
