Regular Sweepings

To maintain the appearance and longevity of your Trex deck in Auburn, CA, regular sweeping is essential.

Frequency: Aim to sweep your deck weekly. This prevents the buildup of debris such as leaves, twigs, and dirt which can lead to stains or the growth of mold and mildew.

Debris Accumulation: Decks are prone to accumulate natural debris:

  • Leaves
  • Twigs
  • Pollen
  • Dust

Tools: Use a soft bristle brush to gently remove debris. A firm brush can damage the composite material.


  • Start from one end and sweep in the direction of the grain pattern to ensure thorough cleaning.
  • In the case of heavier debris, such as after a storm, you may need to sweep more frequently.

Attention to Corners: Pay special attention to the corners and gaps between boards. Debris tends to gather in these areas and can contribute to moisture retention, which should be avoided to maintain the integrity of your deck.

Cleaning Around Objects:

  • Make sure to move planters, furniture, and grills occasionally to sweep underneath and prevent moisture-related damage.

By adhering to these tips, your Trex deck will remain clean and in great condition, providing a beautiful outdoor space for your home in Auburn, CA.

Gentle Scrubbing

When cleaning your Trex deck in Auburn, CA, gentle scrubbing is crucial to maintaining its appearance without causing damage. Use a soft-bristle brush to remove surface debris and dirt. Apply mild soap and warm water to tackle any spots or spills on the deck.

Steps for Effective Scrubbing:

  1. Preparation:
    • Remove all furniture and items from your deck.
    • Sweep the deck to eliminate loose dirt and debris.
  2. Mix Cleaning Solution:
    • Combine 2 gallons of warm water with ¼ cup of mild dish soap.
  3. Scrubbing:
    • Dip the soft-bristle brush into the soapy water.
    • Gently scrub the affected areas in the direction of the grain of the boards to prevent scratching.
    • For isolated stains, apply the soap mixture directly to the stain and let it sit for 10-15 minutes before scrubbing.
  4. Rinsing:
    • Use a garden hose with a gentle spray setting to rinse the deck thoroughly.
    • Avoid using a pressure washer as it can damage the decking material.

Remember to scrub gently to preserve the integrity of the Trex material.

Dos and Don’ts:

  • Do: Test any cleaner on a small, inconspicuous area first.
  • Do: Use a dedicated deck cleaner if needed, according to manufacturer’s directions.
  • Don’t: Use harsh chemicals or abrasive scrubbers.
  • Don’t: Allow soapy water to dry on the deck surface as it may leave a residue.

By following these steps, you’ll effectively clean your Trex deck while avoiding damage. Regular gentle scrubbing can help maintain the beauty and longevity of your outdoor space.

Avoid Pressure Washing

When cleaning your Trex deck in Auburn, CA, exercise caution and avoid using a pressure washer. The high pressure can damage the protective surface, leading to a voided warranty or costly repairs.

Be Aware:

  • Excessive force: Pressure washers can create powerful jets of water that may cut through the deck material.
  • Warranty concerns: Pressure washing is usually not recommended by Trex and could void your warranty.

Follow These Tips:

  • Use a soft-bristle brush and soapy water to gently scrub the dirt away.
  • For maintenance, sweep regularly with a broom to prevent debris accumulation.


  • Trex decks are designed for low maintenance, not high-pressure cleaning.
  • Stick to manufacturer recommended cleaning methods to prolong the deck’s life.

Use Mild Soap

When cleaning your Trex deck, choosing the right cleaning agent is crucial. Mild soap is your best bet for routine deck maintenance. It’s gentle, effective, and won’t damage the composite material.

Equipment You’ll Need:

  • A soft-bristle brush
  • Bucket of water
  • Mild dishwashing soap

Simple Steps to Clean with Mild Soap:

  1. Prepare the Solution:
    • Mix a few tablespoons of mild dishwashing soap into a bucket of warm water to create a sudsy solution.
  2. Test the Soap:
    • Apply the solution to a small, inconspicuous area to ensure no discoloration or damage occurs.
  3. Clean the Deck:
    • Dip your soft-bristle brush into the soapy water.
    • Scrub the deck boards in the direction of the grain to avoid scratching the surface.
  4. Rinse Thoroughly:
    • Use a garden hose to rinse away the soap residue. Do not let the soap dry on the deck surface as it may leave a film.

By strictly using mild soap, you ensure the longevity of your Trex deck’s appearance and condition. It’s a safe and straightforward way to maintain your outdoor living space.

Rinse Thoroughly

When cleaning your Trex decking in Auburn, CA, a thorough rinse using just the right amount of water pressure is crucial to prevent damaging the composite material.


  • Use a hose with a nozzle that allows for a gentle spray.
  • Ensure water pressure is set to not exceed 3100 PSI.

First and foremost, begin by wetting the entire deck surface. Doing this pre-rinses loose debris, making the cleaning process more effective.


  1. Start from one end of the deck, systematically moving towards the other end.
  2. Maintain a consistent 15-20 cm (6-8 inches) distance between the nozzle and the deck surface.
  3. Rinse in a sweeping motion to avoid concentrated water streams, which could mark the surface.

Upon applying a deck cleaner, allow it to sit for the time specified by the product’s instructions. Then, rinse off the cleaner thoroughly, as residual cleaner may attract dirt or cause a film to develop on your deck.


  • Check weather forecasts; aim for a cool, cloudy day to prevent quick drying, which could leave spots or streaks.
  • Water should run off freely, so adjust deck furniture and planters to ensure complete coverage.

Conduct a final walkthrough to inspect the deck. If you notice any missed spots or areas where the cleaner hasn’t been completely removed, rinse these areas again until the water runs clear. Proper rinsing will enhance the beauty and longevity of your Trex decking.

Prevent Stains

Taking good care of your Trex decking in Auburn, California, means ensuring stains don’t settle in and mar its appearance. Here are specific steps to help you prevent unwanted stains:

  • Immediate Action: Promptly clean up spills to avoid stains setting into the material. Drinks, oils, and food should be removed as soon as possible with a soft cloth or paper towel.
  • Protective Measures: Use mats under grills and outdoor kitchens to capture any drippings. For heavily trafficked areas, consider rugs or runners that are colorfast and made from breathable material.
  • Routine Cleaning: Regularly sweeping the deck to remove dirt and debris can significantly reduce the likelihood of stains.
  • Furniture Pads: Place protective pads under outdoor furniture to prevent rust or paint stains.
  • Chemical Awareness: Be cautious with chemicals such as insect repellents and sunscreen, which could discolor the decking. Wipe them up immediately after spills.

Here’s a quick reference for the key steps in stain prevention:

Action Tip
Spill Response Wipe spills immediately with cloth or paper towel.
