Cleaning a Trex Deck
Composite decks are less maintenance than a traditional wood deck, although they still require some maintenance.
Most manufacturers recommend cleaning once a year. Following are the recommendations from Trex for material specific cleaning.
|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||High permanence chalk lines may discolor the surface. Use only Irwin Strait-Line®* 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 “deck 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. The surface must be cleaned within seven days to maintain the stain warranty. To remove, spray off with a hose and use warm, soapy water with a soft bristle brush is recommended to remove the food source and mold.|
|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 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.|
Transcend and Select Railing
|NEVER use acetone or other solvents on Trex Transcend and Select railing to maintain the beauty of the surface. For color transfer issues (from attachment of baluster spacer), use Mr. Clean®, Magic Eraser® Original*** or Magic Eraser® Extra Power to help remove this. For small surface scratches, marks or scuffs, use Dupli-Color Scratch Seal™ Clear Sealer Pen.****|
