How to Clean a Deck

How to Clean a Deck

Regular cleaning of your deck will keep its appearance in tip-top shape and will help minimize deterioration.

Skill Level: Beginner
  1. Step 1 Scrape Off Loose Finish

    Scrape Off Loose Finish

    Remove loose paint or opaque stain with a paint scraper. Scrape down damaged areas to bare wood. Then sand each area to feather the edges of remaining finish material down to bare wood.

  2. Step 2 Scrub the Surface

    Scrub the Surface

    Use a stiff bristle brush to remove flaking stain or dirt. Don’t use a metal-bristle brush on cedar or redwood because the metal bristles may scar the soft wood.

  3. Step 3 Apply Cleaner

    Apply Cleaner

    Apply a deck brightener product to wood surfaces. Mix the product according to manufacturer’s directions. Work the brightener into the wood with a stiff bristle brush, using an extension handle on the brush, if necessary.

  4. Step 4 Power Wash Deck

    Power Wash Deck

    Wash the deck surfaces to remove brightener solution and other residue, using a power washer with a fan spray nozzle. The extra pressure of this tool is necessary to adequately clean the deck. Let the deck dry thoroughly before applying new finish. Be careful power washing cedar deck. Use the low power setting to avoid damaging the wood.
