Millboard decking

Composite decking is an excellent choice for your outdoor living space. It offers the beauty of wood without the hassle of constant maintenance. While composite decking is known for its durability, it still requires some care to maintain its pristine appearance. Regular cleaning is a crucial part of this maintenance routine. In this blog, we'll provide you with a comprehensive guide on how to clean composite decking.


**1. Gather Your Tools and Materials:**


Before you start cleaning your composite deck, it's essential to have the right tools and materials ready. You'll need:


- Broom or leaf blower

- Soft-bristle brush or mop

- Bucket

- Mild soap or composite deck cleaner

- Water hose or pressure washer (optional)

- Non-metallic scrubbing pad

- Rubber gloves (optional)


**2. Remove Debris:**


The first step in cleaning your composite deck is to remove any loose debris. Use a broom or leaf blower to get rid of leaves, dirt, and other loose particles. This initial step will prevent the debris from scratching the surface during the cleaning process.



**3. Sweeping and Washing:**


Fill a bucket with warm water and add some mild soap or a specialized composite deck cleaner. Mix the solution well. Using a soft-bristle brush or mop, start scrubbing the deck's surface, paying extra attention to any stained or dirty areas. The gentle scrubbing will help break down dirt and stains without damaging the composite material.


**4. Rinse Thoroughly:**


After scrubbing the deck, rinse it thoroughly with a water hose. If you have access to a pressure washer, you can use it to make the rinsing process faster and more efficient. Be sure to use a fan tip and keep the pressure low to avoid damaging the composite material. Make sure there's no soap residue left on the deck.


**5. Address Stains:**


For stubborn stains like grease or oil, you may need to take extra steps. Create a paste by mixing baking soda and water and apply it to the stain. Let it sit for a while, then scrub gently with a non-metallic scrubbing pad. Rinse thoroughly. For mould or mildew stains, you can use a mixture of vinegar and water.


**6. Prevent Future Stains:**


To prevent future staining and mildew growth, consider applying a composite deck sealer or protector after cleaning. This will create a barrier that repels stains and provides added protection to your deck.



**7. Regular Maintenance:**


Cleaning your composite deck should become a regular part of your maintenance routine. Depending on your climate and how exposed your deck is to the elements, you may need to clean it once or twice a year. Regular cleaning will help maintain the appearance and longevity of your composite decking.


**8. Avoid Harsh Cleaners:**


It's important to note that harsh cleaners, abrasive brushes, and metal tools should be avoided when cleaning composite decking. These can damage the surface and reduce its lifespan. Stick to mild soap or specialized composite deck cleaners and soft-bristle brushes.


In conclusion, cleaning composite decking is a relatively simple process that, when done regularly, will keep your outdoor living space looking its best. With the right tools and materials, you can remove dirt, stains, and prevent future issues. By following these steps, you'll ensure that your composite deck remains a beautiful and functional part of your home for years to come. Remember, proper maintenance leads to a long-lasting and attractive outdoor living space.
