Composite decking has become a popular choice for outdoor living spaces due to its durability and low-maintenance qualities. However, like any other decking material, it requires regular cleaning to keep it looking its best. One common question that homeowners have is whether it is safe to use a power washer on composite decking. In this article, we will explore the topic and provide you with all the information you need to know.
Can I use a power washer on composite decking?
Yes, you can use a power washer on composite decking. However, it is important to use the right pressure and technique to avoid damaging the deck surface. Composite decks are made from a combination of wood fibers and recycled plastic, so they are more susceptible to damage compared to traditional wood decking.
Choosing the right pressure
When pressure washing composite decking, it is crucial to select the appropriate pressure setting on your power washer. Using too much pressure can strip away the protective coating on the deck boards and result in splintering or warping. It is recommended to keep the pressure below 1500 PSI to prevent any damage.
Preventing damage to the surface
In addition to selecting the right pressure, there are a few precautions you should take to protect the surface of your composite deck. First, always keep the pressure washer nozzle at a safe distance from the deck, approximately 12 to 18 inches away. This will help to distribute the pressure evenly and prevent concentrated spots that can damage the deck.
Cleaning technique for composite decking
When cleaning composite decking, it is important to use a gentle scrubbing motion with a soft brush. This will help to remove any dirt and debris without causing any damage. Additionally, it is recommended to power wash in the direction of the grain to ensure a thorough and even cleaning.
What are the recommended cleaning methods for composite deck boards?
If you prefer not to use a power washer, there are alternative cleaning methods you can utilize to clean your composite deck boards.
Using mild detergent and water
One of the most effective and gentle cleaning methods for composite deck boards is to use a mild detergent mixed with water. This will help to remove any dirt, grime, or stains without causing any damage to the surface. Simply mix the detergent with water according to the manufacturer’s instructions and apply it to the deck with a soft brush.
Gentle scrubbing with a soft brush
To remove any tough stains or spots, gently scrub the affected area with a soft bristle brush. This will help to loosen the dirt and make it easier to remove. Avoid using any harsh scrubbing materials or brushes with stiff bristles, as they can scratch the surface of the deck.
Removing stains and mold
If you notice any stubborn stains or mold on your composite deck, there are specific cleaning products available that are designed to tackle these issues. Look for “deck cleaner” products that are specifically formulated for use on composite decking. Follow the instructions on the packaging and apply the cleaner to the affected areas, using a soft brush to scrub away the stains or mold.
Are there any precautions when power washing a composite deck?
While you can safely power wash your composite deck, there are a few precautions you should keep in mind to avoid any damage.
Keeping the pressure washer nozzle at a safe distance
As mentioned earlier, it is important to keep the pressure washer nozzle at a safe distance from the deck surface. This will help to prevent any concentrated pressure that can damage the boards. Always maintain a distance of 12 to 18 inches between the nozzle and the deck.
Using the correct nozzle tip
The nozzle tip you use on your pressure washer can also affect the pressure and intensity of the water stream. It is recommended to use a fan nozzle tip, as it provides a wider spray pattern and reduces the risk of damaging the decking material. Avoid using a narrow stream or pinpoint nozzle, as these can exert too much pressure on the boards.
Power washing in the direction of the grain
Similar to the cleaning technique discussed earlier, it is important to power wash in the direction of the grain. This helps to ensure an even cleaning and prevents any potential damage to the deck surface. Always follow the natural grain pattern of the boards when power washing.
What cleaning products should I avoid when cleaning my composite decking?
When cleaning your composite decking, it is important to avoid certain cleaning products that can cause damage to the surface.
Avoid bleach or harsh chemicals
One cleaning product to avoid is bleach or any harsh chemicals. These can cause discoloration, fading, or even permanent damage to the deck boards. Stick to mild detergents or deck cleaners that are specifically formulated for use on composite decking.
Using non-abrasive cleaners
Another cleaning product to steer clear of is any abrasive cleaners or brushes. These can scratch the surface of the deck and leave visible marks. Opt for non-abrasive cleaners and soft bristle brushes to protect the integrity of your composite deck.
Choosing eco-friendly options
If you are environmentally conscious, you may want to consider eco-friendly cleaning products for your composite decking. There are numerous eco-friendly options available that are safe to use and do not contain any harsh chemicals or toxins.
What are some alternative methods for cleaning composite decking?
If you prefer not to use a power washer or chemicals to clean your composite decking, there are alternative methods you can try.
Using a broom or brush to remove debris
Regularly sweeping your composite deck with a broom or brush can help to remove dirt, leaves, and other debris. This simple maintenance task can prevent the buildup of dirt and minimize the need for deep cleaning.
Preventing snow and ice buildup
In colder climates, it is important to prevent snow and ice from accumulating on your composite deck. Use a plastic shovel or snow blower to remove snow, and avoid using metal shovels that can scratch the surface. Keep in mind that using chemical ice melt products may cause discoloration, so it is best to use non-abrasive alternatives.
Regular maintenance to avoid deep cleaning
To keep your composite deck looking its best, regular maintenance is key. This includes promptly cleaning up any spills or stains, removing debris, and inspecting the deck for any signs of mold or mildew. By addressing these issues early on, you can prevent the need for deep cleaning in the future.
In conclusion, it is safe to pressure wash composite decking if done correctly. By following the recommended cleaning methods, using the right pressure and technique, and avoiding harsh chemicals, you can effectively clean your composite deck without damaging the surface. Regular maintenance and preventive measures can also help to keep your deck looking beautiful and extend its lifespan. Remember to always refer to the manufacturer’s guidelines and instructions for your specific deck to ensure proper care and maintenance. ###
