Care Guide

Guide to caring for 548 products


Regularly clean your deck with warm soapy water or a light detergent. Rinse after use.

If you use a pressure wash machine make sure the PSI strength is for domestic light use. Be careful not to get too close otherwise damage may be caused to the surface.

To avoid mould build up occasionally brush the deck during cleaning, use a medium stiff yard or hand brush and rinse after use.

There are composite decking cleaners and restorers on the market, be sure to do a test before use.

There will be fading in the first 0-6 months whilst the UV chemicals stabilize. The composite will then acclimatise, revert back to the original colour then slowly fade over the lifespan of the product.


  • Mud, dirt and soil use with warm soapy water, a brush and hose or light power wash.

  • Algae and mould: use an organic path/patio cleaner and rinse after use.

  • Snow melting products or rock salt can be used but must be washed off immediately after thawing.

  • Fat, oil and grease from BBQ’s need a light detergent cleaner and require scrubbing immediately. Do not leave them as they may stain the decking permanently.

  • Alcohol, Fruit and Bird droppings use a light detergent and warm soapy water.
