    Spray deck with soap, then follow by gently scrubbing each deck board with a soft bristle brush. Spray/rinse each individual deck board using a fan tip no closer than 8" from the decking surface. RINSE THOROUGHLY. If dirty water from cleaning is left to dry, this will cause a film to remain on the decking surface. (If you use a power sprayer, it may damage the deck surface and void your warranty.)

    you can save yourself a ton of work by simply washing it with a power washer in which you use a cleaning product for power washers. Works like a charm and saves a ton of time and your back. And be sure to use the proper setting on the power washer so it doesn't do any damage

    DIRT AND DEBRIS

    The affected area should be sprayed off with a hose to remove surface debris. Use warm, soapy water and a soft bristle brush to remove dirt and debris from the embossing pattern.


    CHALK LINES

    Most colored chalks are permanent and may discolor the surface. Use only Irwin Strait-LineĀ®* Dust-Off Marking Chalk (purple) available at www.Irwin.com.


    TANNINS DUE TO DEBRIS

    Remove all debris from deck using a hose or broom. Once the deck surface is dry, apply a "brightener" ** to the deck as directed by the manufacturer. Deck brighteners contain oxalic acid, which will remove tannins.


    ICE AND SNOW

    A plastic shovel may be used to remove snow from the deck. Use calcium chloride or rock salt to melt the snow and ice from the deck surface.


    OIL/GREASE/

    FOOD

    All food spills should be removed as soon as possible. To remove, spray off with a hose and use warm, soapy water and a soft bristle brush to remove spills from embossing pattern.


    MOLD AND MILDEW

    If debris, such as pollen and dirt, is allowed to remain on the deck surface, mold can feed on the biofilm. Using a hose and warm, soapy water with a soft bristle brush is recommended to remove the food source and mold.


    USING A PRESSURE WASHER

    A pressure washer with no greater than 3100 psi*** that has a fan attachment/adjustment and soap dispenser may be used to remove dirt, concrete dust, or other types of construction dirt. Spray deck with soap, then follow by gently scrubbing each deck board with a soft bristle brush. Spray/rinse each individual deck board using a fan tip no closer than 8" from the decking surface. RINSE THOROUGHLY. If dirty water from cleaning is left to dry, this will cause a film to remain on the decking surface.
