Composite decking, especially brands like Trex, TimberTech, and Azek, offers a durable surface with minimal upkeep. Even though it requires less attention than traditional wood decking, composite decks still need regular cleaning to maintain their appearance. Here’s how you can keep your composite deck in Barton Hills looking its best—whether you have Trex or another brand of composite decking.
1. Regular Sweeping of Deck Boards
The most basic step in maintaining your composite deck is regular sweeping. Dirt, leaves, and other debris can accumulate on the surface and, if not removed, may cause long-term damage. Use a broom with soft bristles to prevent scratching and prevent debris from building up in corners and along edges.
Why Sweeping is Essential for Deck Care:
- Regular sweeping prevents organic material from breaking down on the surface, which can attract mold or mildew.
- It keeps the deck free from debris that may leave behind stains or contribute to surface damage when walked on.
Tip for TimberTech and Azek Decks:
TimberTech and Azek decks have a more textured surface than other composite brands. If you don’t regularly sweep away debris, dirt can get trapped in the grooves, especially on the embossed surface. This can lead to discoloration or mildew buildup. For best results, use a broom with soft bristles and a vacuum or blower in areas with high debris accumulation.
2. Removing Stains from Composite Decking
Despite composite decking’s lower maintenance demands, stains are inevitable. Spills from drinks, food, and outdoor activities can create spots that need attention. Fortunately, composite decking is easier to clean than wood and won’t absorb moisture or stains as quickly.
How to Effectively Remove Stains from Your Composite Deck:
- Use a solution of mild detergent and warm water. Apply it to the affected area and scrub with a soft-bristle brush.
- For persistent stains like oil, grease, or ink, use a specialized composite deck cleaner to break down the stain.
Caution:
Avoid using harsh chemicals or cleaners unsuitable for composite materials, as they may cause discoloration or surface damage.
3. Safe Pressure Washing
While a pressure washer can help clean large composite decking areas, it must be used correctly. Too high a pressure setting can damage the decking, while too little pressure will not clean effectively.
Pressure Washing Instructions:
- Set the pressure washer to a maximum of 1200 PSI.
- Hold the nozzle approximately 8 to 12 inches from the deck surface.
- Always direct the nozzle along the direction of the deck boards to avoid causing gouges or warping.
Why Pressure Washing Helps:
- It can remove stubborn dirt, mold, and stains that regular cleaning may not fully address.
- It can revive the appearance of your composite deck without the need for intensive scrubbing.
4. Cleaning Without a Pressure Washer
Not everyone wants to use a pressure washer, and in some cases, it’s unnecessary. However, the correct manual cleaning techniques can still achieve great results.
How to Clean Without a Pressure Washer:
- Mix warm water with a mild dish soap or deck cleaner in a bucket.
- Use a soft brush or sponge to scrub the surface, paying extra attention to areas with stains or buildup.
- For stubborn spots, apply a composite deck cleaner, wait a few minutes, then scrub the area to loosen the grime.
Benefits of This Method:
- Manual cleaning doesn’t carry the risks of using too much pressure or causing accidental damage to the deck surface.
- It’s also a more environmentally friendly option if you’re looking to reduce water usage.
5. Preventing Future Stains and Debris Buildup
Cleaning your deck is an ongoing process. Regular care is key to preventing grime and stains from forming in the future.
Preventive Measures:
- Use a deck cover or outdoor rug in high-traffic spots to avoid dirt accumulation.
- Reseal the deck with a protective coating every few years to make wiping off debris easier and prevent staining.
- Address spills and dirt immediately to avoid stains from setting.
How to Stop Mold and Mildew:
- Mold and mildew will not grow directly on composite decking but will thrive on organic material on the surface, such as leaves or dirt.
- Regularly sweeping the deck and rinsing off the surface with a hose will reduce buildup and help prevent the growth of mold and mildew.
6. Don’t Forget the Railings and Steps
Your deck’s steps and railings also accumulate dust and dirt, affecting its appearance and safety. These areas should be cleaned as part of your regular deck maintenance.
How to Clean Railings and Steps:
- Wipe down the railings with a microfiber cloth and warm, soapy water, especially if there are any built-in features like lighting or decorative elements.
- For steps, use a stiff brush to scrub any dirt or grime that collects in the corners.
Tip:
If you have post caps or decorative elements, clean them carefully to avoid damaging any intricate parts.
7. Mold and Mildew: Key Considerations
Composite decking is resistant to mold and mildew damage. However, these substances can still accumulate on the surface, making the deck slippery and unsightly. While they don’t affect the deck’s structural integrity, they can lead to aesthetic problems.
How to Deal with Mold and Mildew:
- Use warm, soapy water or a specialized composite cleaner to scrub affected areas.
- If you choose a commercial cleaning solution, always follow the manufacturer’s instructions for best results.
For Trex, TimberTech, and Azek decks:
These brands have protective coatings (like Trex Shell Technology or TimberTech Titanium Technology) that resist mold. However, mold can still grow if leaves, dirt, or food are left on the surface. Regularly sweep and rinse with a garden hose to remove debris before it can break down.
A quick rinse is usually enough for Azek decks with smoother surfaces. For Trex and TimberTech, the textured surface may need a soft-bristle brush to clean the grooves effectively.
8. Understanding the Lifespan of Composite Decking
One of the greatest advantages of composite decking is its long lifespan. Unlike wood, which can degrade quickly from weather, pests, and rot, composite decking is designed to withstand the elements without deteriorating. On average, composite decks last between 25 and 30 years. With proper care, they can even surpass this, lasting up to 40 or 50 years.
Why Durability is Important:
- Composite decking resists cracking, splintering, and rotting, which are common issues with wood decks.
- The material is engineered to handle extreme weather conditions, such as the freezing temperatures in Barton Hills and intense sun exposure.
Low Maintenance = Cost Savings:
- While composite decking is more expensive than wood initially, you won’t face the costs associated with sanding, staining, and treating for rot. Over time, composite decking is more cost-effective, requiring little maintenance and avoiding the frequent repairs wood decks need.
9. What You Should Avoid When Cleaning Your Composite Deck
While composite decks are low-maintenance, there are several cleaning mistakes homeowners should avoid to preserve the deck’s surface and functionality.
Don’t Use Abrasive Tools:
- Never use wire brushes, steel wool, or other abrasive materials to clean your composite deck. These tools can scratch or mar the surface, leading to long-term damage.
Avoid Harsh Chemicals:
- Chemicals like bleach, chlorine, or ammonia can degrade composite material over time, causing fading, discoloration, or surface damage. To preserve its integrity, stick to products designed for composite surfaces.
Don’t Let Stains Sit:
- While composite decking is stain-resistant, allowing food or other substances to sit on the surface for an extended period can cause discoloration. Clean spills immediately to avoid the need for deeper cleaning later.
Don’t Let Water Pool:
- While composite decking is water-resistant, allowing standing water to collect over time can lead to mold and mildew buildup. Ensure the deck has proper drainage, and promptly clean up any standing water.
Don’t Use High-Pressure Settings on Pressure Washers:
- High-pressure washers can damage the surface of the composite decking. Always use a maximum of 1200 PSI when using a pressure washer, and ensure the nozzle is held at least 8–12 inches away from the surface.
Don’t Use Non-Approved Cleaners:
- Stick with cleaners specifically made for composite decking. Generic household cleaners or solvents may damage the finish, making your deck look worse over time.
Don’t Ignore the Manufacturer’s Care Guidelines:
- Each brand of composite decking may have different maintenance guidelines. To avoid voiding any warranties, follow the care instructions provided by the manufacturer.
Avoid Cleaning During Extreme Weather:
- Cleaning your composite deck during freezing or extremely hot weather can damage the surface. Clean the deck when temperatures are mild to ensure the best results and avoid any damage from quick-drying cleaners.
Don’t Apply Paint or Stain:
- Composite decking is designed to retain its color naturally. Applying paint or stain can affect the material’s durability and void your warranty.
