It is crucial to choose cleaning agents that are safe and recommended for composite decking to avoid costly repairs or replacements.

Colored or Dyed Cleaners

Some specialized cleaners

While there are specialized cleaners available that claim to be suitable for composite decking, it is important to exercise caution when using colored or dyed cleaners. These products may contain dyes or pigments that can stain or discolor the decking surface. It is recommended to test any colored or dyed cleaning agent on a small inconspicuous area before applying it to the entire decking to ensure compatibility and avoid potential damage.

Colored detergents

Similarly, colored detergents, such as those used for laundry or dishwashing, should not be used on composite decking. The dyes in these detergents can stain or discolor the decking surface, leading to an uneven and unattractive appearance. Stick to clear, non-colored detergents when cleaning your composite decking to maintain its original beauty.
