Easy Ways to Clean Composite Decking: A Complete Guide

Composite decking is a popular choice for many homeowners and can transform your backyard, garden, or outdoor space. Made from a combination of wood and recycled plastic materials, composite decking boards offer a durable option that won’t rot or splinter over time like traditional timber wood decking. 

Composite decking also offers all the aesthetic appeal of natural wood with the bonus of low-maintenance care, allowing you to enjoy your outdoor decking area without any worry about intense upkeep. The color selection available also makes composite decking customizable and easy to match with any home’s style or decor.

Can I Use a Pressure Washer on Composite Decking?

Among the ways to clean composite decking, pressure washing stands out as an effective and efficient method.. Pressure washing with the correct settings can help remove dirt, grime, and mildew from the surface, and the high pressure created by the water eliminates the need for scrubbing or hard labor. 

Using a pressure washer can also reduce the time it takes to clean your composite decking area compared to traditional methods like hand scrubbing or brushing. However, you must use the right setting on your pressure washer to achieve maximum results with minimal damage to your composite decking boards

You should use a gentle pressure washing setting just a couple of times a year to avoid causing any harm or damage. Working with too much pressure can cause irreversible damage by marking the boards, while working at too low of a setting may not be enough power to get rid of tough stains or built-up debris. Be sure to consult a professional if you are unsure which setting best suits your needs before beginning any project!

How to Use a Pressure Washer on a Composite Deck?

When using a pressure washer on composite deck boards, the maximum pressure should be 1,500 PSI, and the power washer should be held at least 10 inches from the deck’s surface. If possible, use the fan attachment on a power washer when cleaning composite decking to spread the water across a wider area. 

When using a pressure washer on a composite deck, move down the length of the deck board and go with the grain, as sweeping a pressure washer from side to side can mark the surface. You should also remember to take a little more time with trims and edges to ensure they are thoroughly cleaned.

Can I Use Soapy Water to Clean the Composite Decking?

Soapy water solutions are a great way to clean composite decking effectively. This type of cleaning method is easy to do and does not require any specialized or expensive equipment or tools. One of the main benefits of using soapy water and a brush to clean your composite decking boards is that it will help break down dirt, grime, and mildew without damaging the boards. 

Additionally, if there are stubborn stains that need extra attention, then a soft-bristled brush may be used in combination with the soapy water solution to scrub them away. Once you’ve scrubbed the deck, you can also use a garden hose with either an adjustable nozzle or sprayer attachment to rinse the surface.

When selecting soap for use in your soapy water solution, you may choose one made specifically for composite decking boards. However, a gentle dishwashing detergent can also work well but avoid harsh chemicals like bleach as they could potentially damage your decking area. Also, make sure the mix ratio is correct – typically one part soap and two parts warm water – to ensure the best results, and always brush in the direction of the grain. 

How Do I Remove Debris from Composite Decking?

Removing debris from your deck is important to keeping your composite decking in good condition and ensuring a long lifespan. It’s best to check for debris regularly and to stay on top of any potential problems before they become more serious. A simple broom is one of the most effective methods for removing debris. However, a leaf blower can also quickly blow away leaves, dirt, and other small debris. 

Regular brushing or sweeping can prevent a build-up of debris from occurring again in the future and ensure dirt isn’t trapped under furnishings. A soft-bristled brush is recommended for sweeping composite decking and should be used along the entire length of the deck board.

Remember not to use too much force when sweeping the surface and go in the direction of the grain to avoid any accidental damage. After sweeping the deck board, you can hose it down to remove any last traces of dirt and clear the gaps.

Composite Decking: A Low-Maintenance Decking Solution

Composite decking offers a low-maintenance option with the same aesthetic appeal as traditional timber wood decking. Keeping your composite deck boards clean by pressure washing or scrubbing your decking boards just a couple of times a year, and debris-free, with regular sweeping, will ensure they continue to look great and prolong their lifespan, so they last even longer! Follow the above advice to ensure your composite deck remains safe and well-maintained.
