In this article, we’ll explore some of the best approaches and answer some common questions about how to clean a Trex deck without a power washer.

What You’ll Need

Before we dive into the cleaning process, let’s take a look at the supplies you’ll need. While you won’t need a power washer, you’ll still need to gather some equipment to get the job done. Here’s what you’ll need:

  • A broom or brush with stiff bristles
  • A bucket of warm water
  • A mild detergent or soap
  • A garden hose with a nozzle sprayer
  • A soft cloth or sponge

Step-by-Step Guide

Now that you have your supplies ready, it’s time to start cleaning your Trex deck. Follow these steps to get the best results:

Step 1: Sweep the Deck

Before you start cleaning, it’s important to remove any loose debris or dirt from the surface of the deck. Use a broom or brush with stiff bristles to sweep the deck thoroughly. Be sure to get into all the nooks and crannies to ensure that all debris is removed.

Step 2: Mix the Cleaning Solution

In a bucket of warm water, mix a mild detergent or soap. Be sure to use a detergent that is safe for use on Trex decking. Avoid using any harsh chemicals or abrasive cleaners, as these can damage the surface of the deck.

Step 3: Apply the Cleaning Solution

Using a soft cloth or sponge, apply the cleaning solution to the deck. Be sure to work in small sections, starting from one end of the deck and working your way across. Allow the solution to sit on the surface of the deck for a few minutes to loosen any dirt or grime.

Step 4: Scrub the Deck

Using a stiff-bristled brush or broom, scrub the deck in a circular motion. Be sure to apply pressure to remove any stubborn dirt or stains. Continue scrubbing until the entire deck has been cleaned.

Step 5: Rinse the Deck

Using a garden hose with a nozzle sprayer, rinse the deck thoroughly. Be sure to remove all traces of the cleaning solution to avoid any residue buildup. Rinse the deck from one end to the other, working in small sections.

Step 6: Dry the Deck

Allow the deck to air dry or use a soft cloth to dry it off. Avoid using a power dryer, as this can damage the surface of the deck.


Here are some common questions that people have about cleaning Trex decking without a power washer:

Q: Is it safe to use a power washer on Trex decking?

A: While power washing can be an effective way to clean a Trex deck, it can also be damaging if not done correctly. High-pressure water can damage the surface of the deck, causing it to splinter or crack. It’s best to avoid using a power washer unless you have experience with this equipment.

A: The frequency of cleaning your Trex deck will depend on a variety of factors, including how much foot traffic it receives, the climate in your area, and whether you have any trees or plants nearby that shed debris. As a general rule, you should aim to clean your Trex deck at least once a year. However, if you notice any buildup or staining, you may need to clean it more frequently.
