Calcium-chloride is an example of a safe and effective compound you can use for melting ice on your decking. Sodium chloride rock salt should not be used for ice melting. The granules may leave permanent unsightly marks on the surface of your decking.

I am sad for all who have the same problems-but please be persistant and keep bugging Trex, your contractor, or store you bought it from-it may help in the end. I installed a Trex deck and screened porch in 2003. Have had problems with it crowning, cracking at the ends of the boards and, of course, constant mold spots. I have tried Corte Clean and Concrobium Mold Eraser with limited success.

If necessary, you may consider replacing individual boards. Using a solid stain will hide the fact that they are new boards.

Products are non-toxic, non-flammable, non-staining , completely biodegradable and safe to use. Product is water-based and may require a second application after rain or other weather conditions. Over a period of time, the effect of static will dissipate naturally on the decking surface. While this is not common, static electricity can occur on walking surfaces in dry climates or in areas where dry winds and dust-borne particles lay on the decking surfaces. If you’ve got a wood deck with mold and deck mildew problems, the most likely cause is neglect. Chances are that you have not treated the deck for a long time.

Complete the job by removing any remaining cleaning solution or mold. The pressure from a hose or power washer will remove some of the surface mold and make the cleaning process easier. Mix the cleaner with water in the spray applicator. All cleaning fluids mix with water for application, but the specific mixture varies depending on which product you use. Check the directions on the product and follow that mixture carefully. Mix the water and cleaner in the spray applicator you'll be using. The oil and grease in food can soak into the composite deck and stain it.

How To Clean Composite Decking

This compound is highly effective at melting ice without damaging the composite surface. It also does not hurt pets if accidentally ingested.

However, oil, grease and some food and beverage stains may require use of a deck cleaner. Composite is a popular decking material that is water, stain, scratch, and mold resistant. Although similar in appearance and workability to wood, composite is stronger, highly durable and with low-maintenance requirements. While green mold growing in the shady areas of your wood deck can be rather unsettling and unsightly, it can be cleaned away with ease if you use the right method. Washing your wood deck regularly with one of our cleaner recipes will also prevent that mold from coming back.

This is an entire weekend job with lots of scrubbing and the power washer. Never mind that we are in drought ridden California and I'm wasting precious water to clean an inferior product. Around June or July when I see there will be several dry days in a row, I use the very expensive stuff. It takes one day of cleaning, another day to dry, and then I apply the Restorer to make the deck more waterproof. This seems to prolong the time between reappearance of mold black spots.

• While composite decking is known for being a step up from wood decking, not all boards are created equal.
• And while no one can guarantee a deck will never develop mold, a capped composite board does provide significant advantages over wood and uncapped products.
• Any exposed wood particles in a board’s core or cap weaken its defense from mold, mildew, and moisture damage.
• This unique blend of ingredients helps the composite decking resist staining and fading, as well as inhibits mold growth.
• Capped polymer and 4-sided capped composite decking provide homeowners with a great alternative to traditional composite and wood decks that are susceptible to mold and mildew.
• Composite decking is made up of a blend of wood particles and plastic materials to form a deck board, thensomeare capped with a synthetic material to help keep moisture out.

If you just had one built, you should be fine. You don’t need to seal new composite decks as they aren’t porous enough to accept a sealer. Over time if the deck begins to absorb water, that’s when you can apply a sealer. But if your deck is new, that shouldn’t be for a long time. Hi our composite deck not only has mildew in areas but has also lost its smooth texture and color. It seems to be waterlogged-doesn’t repel at all. Is there a product that can help restore it?

As you can see it is now peeling and has mold and mildew. I want to either clean it or strip it and clean it. In the end I would like to go with a stain that won’t peel and will help with the mold and mildew.
