How to Clean Trex Decking

Hey there! Dave here, owner of Pink Construction. If you’ve got a Trex deck, you already know it’s one of the best choices out there for durability and low maintenance. But to be honest, even the best decks need a little love now and then. If you’re wondering how to clean your Trex decking, you’re in the right place. I’m going to walk you through everything I’ve learned over the decades I have worked with them, and I’ll even throw in some tips and tricks that’ll make the job easier. Sound good? Let’s get going!

Why Even Bother Cleaning Your Trex Deck?

Okay, so you might be thinking, “Dave, it’s just a deck. How dirty can it really get?” Well, let me tell you, life happens. Spills, pollen, dirt, mildew… it all adds up. And while Trex decking is designed to resist stains and fading, a little regular cleaning goes a long way in keeping it looking fresh. Plus, it’ll help your deck last longer, which means more BBQs, more relaxing evenings, and more memories with family and friends. I think that makes it worth it, right!?

My Step-by-Step Guide to Cleaning Trex Decking

Alright, let’s get down to business. Here’s how I clean Trex decks, step by step:

1. Gather Your Supplies

First things first is getting your cleaning kit together. Here’s what you’ll need:

Here is one we like to use:

• Mild dish soap (yes I’m talking the same stuff you use for your dishes)

• A bucket & warm water

• A clean cloth or sponge (for those stubborn spots)

If you’re dealing with mildew or deep stains, you might want to grab a specialized composite deck cleaner. But for most jobs simple dish soap and water will do the trick.

2. Clear the Deck

Before you start scrubbing just take a few minutes to sweep off any leaves, dirt or debris. I like to use a broom or a leaf blower for this part. Trust me, it’s way easier to clean when you’re not scrubbing dirt into the surface.

3. Mix Your Cleaning Solution

Here’s where I like to keep it simple. Fill your bucket with warm water and add a squirt of mild dish soap. If you’re using a specialized cleaner, follow the instructions on the bottle. Pro tip*: If you’re dealing with mildew, a little white vinegar mixed with water can work wonders and is safe on your decking.

4. Scrub, But Don’t Overdo It

Dip your brush into the cleaning solution and start scrubbing in small sections. I always recommend working in the direction of the deck boards to avoid any unnecessary wear. Being gentle is the name of the game when cleaning your Trex composite decking. No need to go full Hercules here; just enough pressure to lift the dirt and grime.

5. Rinse It Down

Once you’ve scrubbed the whole deck, it's time to grab your garden hose and rinse it thoroughly. Be sure to get all of the soap off because any leftover residue can attract more dirt. I like to start at one end and work my way to the other, just to make sure I don’t miss any spots.

6. Tackle Stubborn Stains

Okay, let’s talk about stains. If you’ve got a grease spot from last week’s burger night or a wine spill that’s overstayed its welcome, don’t panic. For grease, I use a paste made from baking soda and water. Spread it on the stain, let it sit for 10-15 minutes, and then gently scrub it away. For wine or other tough stains, a composite deck cleaner tends to do the trick. Just follow the instructions and you’ll be good to go.

7. Let It Dry

Let your deck air dry after you’ve rinsed everything off. I know it’s tempting to walk on it right away, but trust me you will want to wait until it’s completely dry. This will help prevent streaks and keep your deck looking its best.

My Top Tips for Keeping Your Trex Deck in Great Shape

Clean It Regularly: I recommend cleaning your Trex deck at least twice a year; once in the spring and once in the fall. Basically at the start and end of deck season, especially if you live in MN like me. You might need to do it more often to prevent mold and mildew if you live in an area that gets particularly wet or humid.

Preventative Maintenance: Keep an eye on nearby plants and trees. Overhanging branches can drop leaves and sap, which can make your deck dirtier faster. You can trim them back if needed.

Use Furniture Pads: This is a small thing that makes a big difference. Adding pads under your furniture legs can prevent scratches and scuffs. Plus, it makes the furniture much easier to move around.

Skip the Pressure Washer: I know it’s tempting to break out the pressure washer, trust me, I love that tool. But it can actually damage the surface of your Trex decking if you are using too high of pressure. Stick to a garden hose and a soft brush.

What NOT to Do When Cleaning Trex Decking

Don’t Use Harsh Chemicals: Bleach, ammonia, and other strong cleaners can discolor or damage your deck. Stick to mild soap or cleaners made specifically for composite decking.

Avoid Abrasive Tools: Steel wool or stiff brushes might seem like a good idea for tough stains, but they can scratch the surface of your deck. Avoid them at all costs!

Don’t Let Stains Sit: The sooner you tackle a stain, the easier it is to remove. If you spill something, clean it up as soon as possible. Easier said than done, I know!

A Little Effort Goes a Long Way

At the end of the day, cleaning a Trex deck doesn’t have to be a chore. With the right tools and a little know-how, you can keep your deck looking fantastic for years to come.
