10.  Never use shovels or sharp edges to remove snow and ice from your deck.

9.  Place a vinyl-backed splatter guard mat underneath your grill.

8.  For oil and grease stains, speedy clean up is the best. The longer the oil or grease sits on the surface the most likely it is to soak into composite wood fibers.

7.  Use extreme caution with pressure washers when cleaning your deck. Use at pressures less than 3,000 psi at 10” above the deck surface.

6.  Keep debris out of gaps between the decking boards so rain showers can remove pollen

5.   If mold is present on your deck, there are many commercial products available for cleaning mold. We recommend the following commercial cleaners.

  • 30 Seconds® Outdoor Cleaner by Collier Manufacturing, LLC is safe to use around lawn and plants when used as
    directed and is biodegradable once rinsed into the soil.
  • Composite Deck Cleaner & Enhancer by Expert Chemical Company is a heavy duty, mildly alkaline chlorinated mold and
    mildew remover/cleaner.

Strictly follow manufacturers’ instructions.

4.  Clean your deck as often as needed, at least twice each year.

3.  Maintain a deck that is dry and clean. Dislodge accumulated dirt with a broom or by using soap, water and a scrub brush, scrubbing in the direction of the grain pattern.

2.  Improve drainage or grade soil to eliminate standing water under decks. Direct downspouts, downspout extensions and splashguards away from decks.

1.  Ensure adequate ventilation under and between decking boards to prevent mold growth.
