Cleaning your Trex Deck.

Cleaning your Trex Deck a few times a season is really no more difficult than cleaning a floor inside your home. A mop, or bristle brush with some soap and water and you are ready to go.

 Below we have posted Trex’s recommendation for cleaning.

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-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 “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 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.
