This is a multipurpose product specialy formulated to remove grime, dirt, and oily deposits from concrete, steel, and wooden decks.

Note: Deck cleaners are not designed to remove old stains. You would need a deck stain stripper for this.

Many of the older deck cleaners contained the active ingredient called Sodium Hypochlorite or what is commonly known as “bleach”. These deck cleaners will contain bleach that “whiten” the wood and some additional soapy surfactants that will aid in the cleaning of dirt and grime. Bleach based cleaners have recently been found to damage the wood’s lignin that help bind the cellular structure of the wood.
