In this article, we are going to cover what actually is “Wood Deck Cleaner”. We will compare the different types of deck cleaning options available and what are the positives and negatives of each.
Exterior wood and deck cleaners are designed to clean and prep your exterior wood prior to an application of a wood stain. These cleaners come in many different concentrates with different ingredients. The main purpose of deck cleaners is to remove contaminants such as dirt, oxidation (graying), mold, algae, and in some cases, a very deteriorated stain that has failed. Deck cleaners are typically made up of caustics soaps that will aid in the scrubbing or pressure washing of your wood during the prepping process. Most deck cleaners will raise the pH balance of the wood resulting in a neutralizing acid (deck brightener) application to cancel the caustic of the cleaner, leaving the wood in a neutral state.
Note: Deck cleaners are not designed to remove old stains. You would need a deck stain stripper for this.
