A wood deck requires maintenance just like any deck surface. The wood is highly durable in outdoor conditions and typically requires nothing more than an occasional cleaning when residue accumulates. Instead of using bleach or a commercial cleaning product that is filled with chemical ingredients, safely clean the wood deck with a vinegar mixture that works just as well without use of harsh chemicals.
Sweep the deck with a broom to remove loose soil.
Rinse down the deck with your garden hose to remove stuck-on buildup.
Fill a bucket with about 1 gallon water from the hose and 1 cup white vinegar.
Dip either a broom or nylon scrub brush into the cleaner, and scrub across the wood deck following the direction of the wood grain.
Rinse the deck after cleaning and allow to air dry. The vinegar not only cleans but also removes mold and mildew growth.
