Can You Pressure Wash Trex Decking?
Trex decking has become a popular choice for homeowners who want a low-maintenance, long-lasting outdoor living space. Made from a blend of wood fibers and recycled plastic, Trex decking offers the natural look of wood without the maintenance requirements.
Over time, dirt, grime, and other outdoor debris can build up on the surface of Trex decking, leaving it looking dull and discolored. One way to quickly and effectively clean Trex decking is by using a pressure washer. But, can you pressure wash Trex decking without causing damage?
Here is the answer to that question and provide some tips for pressure washing Trex decking safely and effectively.
Trex manufacturer’s recommendation
According to Trex, a leading manufacturer of composite decking, pressure washing is an acceptable method for cleaning Trex decking, but it should be used with caution. Trex recommends using a fan tip nozzle with a pressure of up to 3100 psi, held at least 8 inches away from the deck surface.
They also caution against using high-pressure settings or concentrated streams, which can damage the deck’s surface. Moreover, Trex advises against using bleach or other harsh chemicals, which can discolor the deck.
Follow the manufacturer’s guidelines and use proper techniques to ensure the longevity and beauty of your Trex deck.
Advantages of pressure washing Trex decking
Pressure washing Trex decking has several advantages. Firstly, it can help to maintain the appearance and cleanliness of the deck, removing dirt, grime, and stains that have built up over time. Secondly, pressure washing can be an efficient way to clean a large deck quickly, saving time and effort compared to using traditional cleaning methods.
Pressure washing can help to prevent the growth of mold and mildew, which can be a problem in damp or humid environments. Pressure washing can help to prepare the deck for staining or sealing, by removing any old coatings or residues that might interfere with the adhesion of the new finish.
On the other hand, use the appropriate pressure setting and technique when pressure washing Trex decking, to avoid damaging the surface or causing other problems.
Disadvantages of pressure washing Trex decking
While pressure washing Trex decking can be a quick and effective way to clean it, there are also some disadvantages to consider. One major disadvantage is that pressure washing can potentially damage the surface of the decking if the pressure is too high or if the nozzle is too close to the surface. This can result in scratches, gouges, or other types of damage that can affect the appearance and longevity of the decking.
Another disadvantage is that pressure washing can strip away the protective sealant that is applied to Trex decking during manufacturing. This sealant helps to protect the decking from the elements and keep it looking new for longer. If the sealant is removed, the decking may be more prone to fading, staining, or other types of damage.
Eventually, pressure washing can also cause water to be forced into the gaps between the decking boards, which can lead to rot or other types of damage over time. To avoid these issues, use the correct pressure setting, nozzle type, and technique when pressure washing Trex decking, and to take care not to apply too much pressure or get too close to the surface.

Alternative Cleaning Methods for Trex Decking
There are some alternative cleaning methods that can safely and effectively clean your Trex decking without the risk of damage. Here are some of the best alternative cleaning methods for Trex decking to help you keep your deck looking its best for years to come.
Manual cleaning
Manual cleaning is a viable alternative to pressure washing Trex decking. This method involves using a soft-bristled brush and a mixture of warm water and mild detergent to scrub the deck’s surface.

While this method requires more elbow grease than pressure washing, it is gentler on the deck and helps avoid any potential damage to the surface or the deck’s protective coating. Also, manual cleaning allows you to pay closer attention to any spots or stains that require extra attention.
Chemical cleaning
Chemical cleaning can be an effective method for cleaning Trex decking, but it should be used with caution. Before using any chemicals on your deck, read the manufacturer’s instructions and follow them carefully. Some chemicals can damage the surface of the decking or discolor it, choose a product that is safe for use on Trex.
One option for chemical cleaning is to use a product specifically designed for Trex decking, such as the Trex Deck Cleaner. This cleaner is formulated to remove dirt, grime, and other stains without damaging the surface of the decking. Follow the instructions on the product label, including the recommended dilution rate and application method.
Another option for chemical cleaning is to use a mild household cleaner, such as dish soap or laundry detergent. These cleaners should be diluted with water and applied with a soft-bristled brush. Rinse thoroughly with water after cleaning to remove any residue.
Some chemicals, such as bleach, should not be used on Trex decking as they can cause discoloration and damage to the surface. Furthermore, pressure washing should not be used in conjunction with chemical cleaning, as it can also damage the surface of the decking.

Pressure Washing Explained: For Trex Decking
Pressure washing is a technique that involves using high-pressure water to remove dirt, grime, and other types of debris from a variety of surfaces.
Here are the benefits of pressure washing, how it works, and whether it is safe to pressure wash Trex decking.
Types of pressure washers for Trex decks
In the context of pressure washing Trex decking, it’s essential to understand the different types of pressure washers available. There are three main types of pressure washers: electric, gas-powered, and hydraulic. Electric pressure washers are best for small to medium-sized cleaning tasks, while gas-powered pressure washers are more suitable for larger and tougher jobs.
Hydraulic pressure washers are the most powerful and can handle heavy-duty tasks.

Tips for using a pressure washer while pressure washing Trex
When pressure washing Trex decking, follow some essential tips to ensure you don’t damage the surface of your deck. Here are some valuable tips for using a pressure washer on Trex decking:
- Use the Right Pressure: Use a pressure washer with a maximum pressure of 3100 psi and a fan tip nozzle. Avoid using a concentrated nozzle, as it can damage the decking material.
- Keep a Safe Distance: Keep the pressure washer nozzle at least 8 inches away from the deck’s surface. Closer than that can lead to splintering or chipping of the wood.
- Pre-Wet the Deck: Pre-wet the deck with water before using the pressure washer. This helps to soften and loosen any debris, making it easier to remove.
- Clean in the Right Direction: Clean the deck in the direction of the wood grain to avoid damaging the surface. Avoid directing the nozzle towards the edges or corners of the deck, as this can cause damage.
- Use the Right Technique: Use a sweeping motion to clean the deck. Avoid keeping the nozzle focused on one spot for too long, as this can cause damage.
By following these tips, you can effectively pressure wash your Trex decking without causing any damage, and keep your deck looking great for years to come.
Potential risks of pressure washing
While pressure washing can be an effective way to clean Trex decking, be aware of potential risks.
- Too much pressure can damage the surface of the decking, leading to scratches and other types of wear and tear.
- Using the wrong type of nozzle or detergent can cause discoloration or other damage to the decking.
- Pressure washing can force water and cleaning solution deep into the decking’s pores, which can lead to mold and mildew growth if not properly addressed.
Conclusion
Trex decking can be pressure washed, but it’s crucial to do it with caution. Using the wrong pressure or nozzle can cause harm. A patch test on a tiny, concealed section is always suggested to ensure no damage occurs.
In conclusion, while pressure washing can be used to clean Trex decking, it should be done with caution and following the manufacturer’s recommendations to avoid potential damage. Trex, a composite decking material made of wood and plastic, is designed to be low-maintenance and resistant to many common issues that affect traditional wood decks, such as rot, warping, and insect damage.
However, pressure washing Trex decking with excessive pressure, using a narrow spray nozzle, or holding the nozzle too close to the surface can potentially damage the decking material, resulting in fading, scratching, or even permanent damage.
