In the realm of outdoor living, solid composite decking has emerged as a game – changer. As a supplier of solid composite decking, I’ve had numerous conversations with customers about its various features, and one question that frequently pops up is: "Is solid composite decking easy to clean?" In this blog, I’ll delve deep into this topic, sharing insights based on my experience and industry knowledge. Solid Composite Decking

The Composition of Solid Composite Decking
Before we discuss the cleaning aspect, it’s essential to understand what solid composite decking is made of. Solid composite decking typically consists of a blend of wood fibers, recycled plastics, and additives. The wood fibers give it the natural look and feel of real wood, while the plastic provides durability and resistance to rot, insects, and moisture. The additives are used to enhance properties such as UV resistance, color stability, and fire retardancy.
This unique composition plays a significant role in determining how easy it is to clean the decking. Unlike natural wood, which is porous and can absorb dirt, stains, and moisture, the non – porous nature of solid composite decking makes it less likely to hold onto contaminants.
Routine Cleaning
Routine cleaning of solid composite decking is a breeze. All it usually takes is a quick sweep with a broom to remove loose debris such as leaves, twigs, and dirt. This simple step should be done regularly, especially during the fall when leaves are abundant or after a windy day.
For a more thorough clean, a garden hose can be used. Simply spray the decking with water to wash away any remaining dirt. The smooth surface of solid composite decking allows water to run off easily, taking the dirt with it. You can also add a mild detergent to the water for a bit of extra cleaning power. A solution of warm water and a small amount of dish soap is usually sufficient. Use a soft – bristle brush to gently scrub the surface in a circular motion. This will help to loosen any stubborn dirt or stains without scratching the decking.
After scrubbing, rinse the deck thoroughly with clean water to remove all traces of the detergent. Make sure to get into all the corners and crevices to ensure a complete clean. Once the deck is rinsed, let it air – dry. In most cases, routine cleaning like this can be done once a month or as needed, depending on the amount of foot traffic and exposure to the elements.
Removing Stains
While solid composite decking is resistant to many types of stains, it’s not completely impervious. However, the good news is that most stains can be easily removed.
Food and Beverage Stains
Spills from food and beverages are common on outdoor decks. For light stains, the routine cleaning method described above should do the trick. If the stain is more stubborn, you can create a paste using baking soda and water. Apply the paste to the stain and let it sit for 10 – 15 minutes. Then, use a soft – bristle brush to scrub the area gently. Rinse with water, and the stain should be significantly reduced or completely removed.
Oil and Grease Stains
Oil and grease stains can be a bit more challenging, but they’re still manageable. Start by blotting up as much of the oil as possible with a paper towel or absorbent cloth. Then, sprinkle a generous amount of cornstarch or baking soda over the stain. Let it sit for a few hours to absorb the oil. After that, sweep away the powder and clean the area with a mild detergent and water solution. If the stain persists, you can try using a specialized composite deck cleaner. These cleaners are formulated to break down tough stains without damaging the decking.
Mold and Mildew
In areas with high humidity or poor ventilation, mold and mildew can grow on the decking. To remove mold and mildew, first, mix a solution of one part bleach and three parts water. Put on protective gloves and eyewear, and use a spray bottle to apply the solution to the affected areas. Let it sit for 10 – 15 minutes, but don’t let it dry on the deck. Then, use a stiff – bristle brush to scrub the area. Rinse thoroughly with water to remove all traces of the bleach solution. Regularly cleaning and ensuring good air circulation around the deck can help prevent mold and mildew growth in the first place.
Comparison with Other Decking Materials
When compared to other decking materials such as natural wood, pressure – treated wood, and PVC decking, solid composite decking has distinct advantages in terms of cleaning.
Natural wood decks require regular staining and sealing to protect them from the elements. These treatments not only add to the cost but also make the cleaning process more complicated. If the stain or sealant wears off, the wood can absorb dirt and moisture more easily, leading to stains, rot, and insect infestations. Cleaning a natural wood deck often involves sanding and refinishing, which can be time – consuming and labor – intensive.
Pressure – treated wood is more durable than natural wood, but it still requires maintenance. The chemicals used in the treatment can leach out over time, and the wood can still be susceptible to mold and mildew. Cleaning pressure – treated wood may involve using harsh chemicals, which are not only bad for the environment but can also be dangerous to handle.
PVC decking is relatively easy to clean, similar to solid composite decking. However, PVC decking can be more prone to scratching and fading over time. Solid composite decking, on the other hand, offers better scratch resistance and color retention, making it a more long – lasting and low – maintenance option in the long run.
Tips for Keeping Your Solid Composite Decking Clean
- Use doormats: Place doormats at the entrances to the deck to prevent dirt and debris from being tracked onto the surface.
- Trim nearby plants: Overhanging branches and plants can drop leaves, flowers, and sap onto the deck. Regularly trim them to minimize the amount of debris on the deck.
- Avoid using abrasive cleaners and tools: Abrasive cleaners and tools can scratch the surface of the decking, making it more susceptible to stains and damage. Stick to mild detergents and soft – bristle brushes.
- Clean up spills promptly: The longer a spill sits on the deck, the more likely it is to leave a stain. As soon as a spill occurs, clean it up right away.
Conclusion
In conclusion, solid composite decking is indeed easy to clean. Its non – porous surface, resistance to stains, and durability make routine cleaning a simple task that can be accomplished with minimal effort and resources. Whether it’s removing everyday dirt, food and beverage stains, or more stubborn issues like mold and mildew, there are effective and straightforward cleaning solutions available.

Compared to other decking materials, solid composite decking offers a superior combination of low maintenance and long – term performance. If you’re in the market for a decking material that will not only enhance the beauty of your outdoor space but also save you time and money on maintenance, solid composite decking is an excellent choice.
