Top-Rated Wood Deck Cleaners

The purpose of wood deck cleaners is to remove dirt, mold, algae, and oxidation (graying). Many different brands and formulations of wood deck cleaners are available in the marketplace, and they can be applied using a variety of methods e.g., spray, scrub, or power wash.Because most deck cleaners raise the pH in wood, it is important after using a cleaner to neutralize the pH. This is most commonly achieved using a deck brightener. This bulletin does not include surveys on deck brighteners but are included with other products surveyed.

We compiled the most highly-rated products listed below based on nine wood cleaner tests and surveys conducted in 2022 and 2023.

Please Note. Cleaners containing chlorine bleach are not recommended for cleaning treated wood.

Do not use chlorine bleach to clean treated wood decks.

Excessive use of chlorine bleach containing cleaners (sodium hypochlorite or calcium hypochlorite) can damage treated wood leaving it with an unnatural whitewashed appearance. Chlorine bleach also can raise the wood fibers and cause a fuzzy-looking surface.Chlorine bleach (sodium hypochlorite) breaks down the lignin in wood causing excessive damage to wood cells. The natural pH of wood is slightly acidic, and bleach is a basic solution. As a result, use of bleach on wood shifts the pH from near neutral pH to a basic pH that will damage the cellular structure.

  • Bleach corrodes metal fasteners, screws and nails.
  • Bleach can cause damage to surrounding plants.
  • Bleach, after several months, lightens wood's natural color.
  • Bleach does not eliminate the spores from which mold and mildew grow.
