How to Clean a Wood Deck

Many homeowners have to clean their wood decks annually. If decks aren't cleaned when they are dirty, the homeowner may have problems with rotting or splitting on their deck which may shorten the life span of their wood deck. Although this annual chore may be tedious for most, the equipment needed is minimal and are items you may even have in the garage already.

  1. Clear and remove all items off your deck.

  2. Mix the oxygen bleach and warm water together in a bucket. The ratio should be six ounces of bleach to each gallon of water. Use the toilet brush to stir the mixture and to help dissolve the bleach powder in the water.

  3. Place the mixture into a standard sprayer. Spray the deck generously with the bleach mixture and let sit for at least fifteen minutes before scrubbing.

  4. Scrub the wood deck with a stiff brush and use the toilet brush around the railings.

  5. Rinse the area you have scrubbed with water.


  • Keep the oxygen bleach away from small children.
