How to Maintain Aztek TimberTech Decking

Maintaining Your Aztek TimberTech Products for Longevity

Taking care of your TimberTech deck or porch is essential to maintain its beauty and longevity. With just a few simple tips, you can keep your deck looking great for years to come. Here are some care tips for your TimberTech product to keep it in top shape:


Recommended Cleaning Products:

Use the recommended cleaning products in the below guide to make care and cleaning easier and to ensure proper care. Always read and follow the instructions carefully. If using a cleaning product other than TimberTech DeckCleaner™ or one of the recommended products, contact the manufacturer first.


Cleaning is required every three months for aluminum products located within 1,500 feet of a body of salt or brackish water or in areas influenced by other airborne contaminants. For those located more than 1,500 feet from a body of salt or brackish water or in areas influenced by other airborne contaminants, cleaning is required every six months.

By following these simple steps, you can ensure that your DSI aluminum products remain in great condition for years to come.


    For the best results when cleaning your deck, use the recommended brushes below: AZEK Decking, AZEK Porch: a stiff, natural fiber brush (e.g., Blue Hawk Deck Scrub Brush, Quickie® Jobsite Deck Brush) PRO Decking, EDGE Decking, ReliaBoard® and DockSider™: a medium to stiff nylon brush (e.g., Quickie® Bulldozer™ Poly Fiber Deck Brush)

      General & Spot Cleaning:

      Dilute TimberTech DeckCleaner mixing 1 part cleaner to 3 parts water. One gallon of diluted cleaner will cover approximately 1,000 square feet of surface area. Working in one smaller area at a time, saturate with the diluted cleaner and allow it to stand on the surface for 30-60 seconds. Do not allow the cleaner to dry or evaporate before scrubbing. Using the recommended brush and extension handle, scrub using downward pressure. First, scrub in the direction of the grain and then against the grain working the cleaner into the surface texture. Rinse the treated area with clean water. For best results, dry or remove standing water with a towel or sponge mop. Allow the deck to air dry completely.

        TimberTech AZEK, PRO, and EDGE Cleaning Instructions:

        Capped Polymer and Capped Composite Decking Composite deck cleaners, such as Corte Clean®, Thompson’s® Water Seal®—Oxy Action, Olympic® Deck Cleaner, or other cleaners specified as composite deck cleaners, in powder or liquid form, should not be used with TimberTech AZEK Deck or Porch, TimberTech PRO, and TimberTech EDGE collections. The capping material on these products is not composed of a wood-plastic composite.

          TimberTech AZEK, PRO, and EDGE Cleaning Instructions:

          Recommended Products For General Cleaning: Dirt, Grime, Tannin, and Mildew Stains Although TimberTech products are low-maintenance, we recommend periodic cleaning to help maintain the beauty of the product. ReliaBoard® and DockSider™ are composite products, and can be cleaned using a solution of warm water and mild detergent. Use a soft-bristled brush to gently scrub the surface, working in the direction of the grain. Rinse thoroughly with clean water and allow to air dry.

          For TimberTech AZEK, PRO, and EDGE collections, the use of a composite deck cleaner, such as those mentioned above, is not recommended. Instead, use TimberTech DeckCleaner™ or a recommended alternative.

          For stubborn stains, such as oil, grease, or wine, use a solution of warm water and mild detergent along with a soft-bristled brush. Rinse thoroughly with clean water and allow to air dry.

          To prevent stains from setting, clean up spills as soon as possible using the recommended cleaning products and techniques. Avoid using abrasive cleaners or pressure washers, as they can damage the surface of your TimberTech product.
