Cleaning Composite Trex Decks

Compared to wooden decking, which requires extensive care and maintenance to stay clean and to look sharp, capped composite decking requires little maintenance or cleaning. Rinse with a high-pressure nozzle until the water coming from the deck runs clear to ensure a film doesn’t remain.

Any decking material exposed to the outdoors is susceptible to mold/mildew growth especially in climates with higher humidity levels. Water left pooling on the surface or inside your deck can create problems such as mold/mildew growth, deck rot, and warping. The good news is that mold can be prevented with a simple but consistent application of a moisture barrier. Once again, choosing the correct product is crucial to successfully protect your deck from mold.

As with any walking surface, TimberTech Deck or Porch products may become slippery in freezing weather. For ice removal, most products containing calcium chloride can be used without damage to the deck or porch surface. These products may leave a white residue which can be cleaned using the cleaning guidelines in the previous pages.

How to Clean Wood Deck

Removing Mold, Tree Sap And Mildew Stains On Composite Deck Railings

Rinsing is required so care should be taken to not use hard water for this purpose, and if it must be used, dry with a cloth or use a blower to dry surfaces. Even small amounts of oxygen bleach can leave discolored spots on your composite deck; avoid using bleach products and try a different stain remover or make your own. Spraying your deck with soap, followed by gently scrubbing each individual deck board is the best way to make your composite deck shine. However, if your deck boards are still dull, try using Resist Mist. This product not only rids your boards of mold, tree sap, mildew, and grease/food stains, but it also leaves the deck shining and looking brighter. Resist Mist also has the ability to prevent mold, mildew and algae from growing again. Mold and mildew can grow on nearly any building material.

Pressure Washing Your Composite Decking

On the other hand, when it comes to the best way to clean composite decking, the answer looks quite different from cleaning methods for natural decking. To maintain the beauty and functionality that you want from your deck, a little care and cleaning can go a long way. You can then use your garden hose or a pressure washer to rinse the surface of the deck. Try to time your deck cleaning project for nice weather.

• All-purpose wood deck cleaners contain detergents to dissolve surface dirt, spills, and grime.
• Rusty streaks can also appear around screw heads or along the wood’s grain.
• These cleaners are usually sprayed on, worked into the grain with a deck brush for even coverage, and then rinsed off with a garden hose.
• The cleaners are typically applied to the decking with a sprayer or deck brush, spread evenly with a mop, and then rinsed off with a garden hose.
• Even if they’ve been sealed, wood decks, especially cedar and redwood, eventually begin to dull and take on a weathered, gray appearance.

Address stains as soon as possible, and make sure your deck continues to maintain adequate drainage to prevent mold and mildew from growing.
