Composite Decking Maintenance And Cleaning

Ultra-Decking offers little or no maintenance compared to regular wood or timber decking. You still need to take care of your composite deck from Ultra Decking, but nothing compared to maintaining regular wood decking.

Avoid water puddles building up on your decking, it can lead to increased fading over time (First generation decking only).

Don’t let liquid spillage sit on traditional first-generation composite decking. Wipe away with a damp sponge or cloth and sweep clean with a soft brush. Composite decking is made with recycled plastics and wood fibres with dirt & dust easily absorbed into the boards after rain or snow.

A quick hose down and a soft brush will ensure your decking looks great for decades to come. No need to worry about the yearly task of resealing, staining or dealing with splinters, even worse slipping on your old wooden deck.

Below are a few tips to help you keep your composite decking looking great and to ensure little or no maintenance for years to come. Following these tips will help keep your new composite decking to stand up to the elements and give you a great place to relax and enjoy your deck and garden, every day.


All outdoor decking requires cleaning. Composite decking is ultra-low maintenance, but this doesn’t mean maintenance free. Some general cleaning will ensure the life span of your Ultra-Decking for decades to come. When cleaning, firstly use a broom or soft brush to remove any excess leaves and debris leaving the surface area ready to be cleaned. Using a garden hose or apply a bucket of warm water to clean the surface area of your decking. Once applied use a soft-bristle brush to scrub the surface of the decking area. Then prepare a bucket of warm light soapy water and apply, leave to stand for several minutes, then simply wash down with a garden hose or bucket of clean water and leave to dry.


If used correctly, Ultra-Decking do recommend using a pressure washer on a very low setting no closer than 8 – 12 inches to the composite decking area. A high-pressure washer can open the surface material causing issues like chipping, sun damage and mould staining. Please note: A garden hose with a quick sweep using a soft brush will be more than enough to keep your deck looking as good as new.


In Ultra Decking experience and research an oxygenated cleaner is the best cleaning product to use. When you first choose to purchase a cleaning product for your composite decking, always check the label and ensure chlorine bleach-based deck cleaners are never used on your new deck. When applied, Chlorine bleach is extremely corrosive to any surface or material and will literally eat away at any material it meets. It will also discolour the deck, damage the surface and enhance mould and mildew build up. To avoid these issues chose a non-toxic, sodium bicarbonate based cleaner.

Forgetting The Gaps

When cleaning your composite decking with a quick wash using your garden hose and a soft brush, don’t forget to clean the gaps between the decking boards. This will keep air passing between the boards and stop any dirt and debris building up under the decking area.

Using The Wrong Tools

If you do choose to do a deeper clean than a quick garden hose wash, please ensure you always use a soft bristle scrub brush. With a build-up of snow use a plastic shovel when possible.
