How Do You Clean Trex Decking in Colorado Springs?

How Do You Clean A Trex Deck?

Removing Debris & Spills

Using a water hose, clean the surface of your deck. Using water to rinse the deck surface will remove any dirt, dust, pollen, or other material that has accumulated. It will be necessary to scrape away the material that has been accumulating for some time.

To ensure that you have the power you require, set your nozzle to spray. If you decide to use a power washer, be sure that the pressure is less than 3100 psi so that you don’t harm your custom decking material.

Dish soap and water should be mixed together. Because dust and filth will most likely be trapped in the ridges of your desk, you’ll need to scrub with a bristle broom or brush to remove them.

Scrub the whole deck with a bristle broom, paying particular attention to the ridges. Make certain that all dirt and debris is removed from the deck, as failure to do so will result in the staining of the deck.

This method of cleaning your deck should be repeated every six months. This will aid in preventing stains from appearing on your deck.

Things You Will Need:

  • Hose
  • Spray nozzle
  • Ammonia – free dish soap
  • Plastic bucket
  • Bristle broom or brush

Using Specialized Cleaner For Deep Stains

It is preferable to use a composite deck cleaner that contains sodium hypochlorite since it is more effective on Trex decks. Don’t use any cleansers on your Trex deck unless they are expressly certified for use on Trex decks.

Chemicals and solvents can cause damage and staining to your deck, as well as voiding any warranties that you might have.

Remove any surface dirt and debris from your deck by sweeping it. The deck should be cleaned with a standard broom, and the ridges should be cleaned with a little brush.

Fill the pump spray container halfway with water and your cleaner. If you look on the back of the cleaning bottle, you should see the water to cleaner ratio.

If you decide to use a pressure washer, there should be a little compartment on the side of the machine where the cleaner may be stored. Maintain a low pressure setting on your pressure washer.

Spray the cleanser all over your deck in a sweeping manner, then scrape it with a broom or use the pressure washer in a sweeping motion to clean it. When using a pressure washer, do not let the spray to settle in one spot; instead, move with it to avoid damaging your deck.

Allow the cleaner to rest for approximately 15 minutes before using it. Make certain that you fully rinse your deck so that you don’t end up with any stains. You may use your pressure washer to rinse without having to put any cleaning in it at first.

If there are any parts that are still discolored, combine cleanser and water in a bucket and scrub the stain with a gentle brush with bristles. After cleaning, be sure to thoroughly rinse the area.

Please keep in mind that you should be extremely cautious about how hard you clean. Scrubbing the deck too aggressively will result in the surface becoming worn away.
