How to clean Mold and Mildew off Composite Decking

 

The effects of mold are generally more serious than those of mildew. Mold damage structures and cause serious long-term health issues. Reactions include breathing issues, fatigue and migraines.

Furthermore, those with a mold allergy could experience sneezing, congestion and eye, skin and throat irritation. For this reason, its critical that you remove mold from your deck as soon as possible. While composite decking is resistant to many things, it is not impervious to mold and mildew. Luckily, removing mold from your deck is not difficult. Just follow these steps:

 

  1. Pressure wash. Using a pressure washer, remove as much of the mold as you can.
  2. Prepare a solution. Make a solution of vinegar and water with two-parts vinegar and one-part water.
  3. Pour the solution. Pour your solution on top of the moldy area, then sprinkle baking soda on top.
  4. Wait. Let the baking soda and vinegar sit for 20 minutes or more.
  5. Scrub. Take a medium-to-course bristle brush and scrub the area until you’ve removed all residual mildew and mold.
  6. Rinse. Using clean water, rinse the area.
