CompoCare before and after

How to Clean and Maintain Composite Decking

Composite decking is an alternative to hardwood timber decking that is not only attractive but also practical and due to its manufacturing process, is long-lasting.

Keeping your composite deck looking its best requires a small amount of maintenance every so often, but fear not, it is easier than you might think.


One of the easiest ways to keep your deck looking spic and span is by simply giving it a regular clean. This doesn’t need to be a long or difficult task.

A simple brush over with a stiff broom once a week and perhaps a wash with a little soap and water for any dirt or stain removal will help keep your deck looking better for longer.

Composite Wood Deck Cleaning

Before and after using Compo-Clean

Just like real timber, composite wood can also fade and slightly discolour over time due to weathering, UV rays and fluctuation in temperatures.

Left unattended you will find that dirt will become trapped in the wood grain and will not be able to be removed without specialist treatment. If this happens, you will need to use a cleaner specifically designed for this reason.

We recommend using a product such as Compo-Clean. It is able to penetrate into the wood, offering a deep and premium clean.

It is a water-based gel formula perfect for use in the garden as it is safe to use around plants and shrubs and will not drip.

Caring For And Preserving Your Deck

You may find that even after having the best cleaning products applied, your deck just doesn’t look as good as it once did. Unfortunately, this can happen if areas have been left unattended from the damaging effects of the weather, or if it is in a heavy traffic area.

It is also possible for overexposure of weathering and temperate fluctuations to cause the wood so become weak and split or crack – something you will really want to avoid!

Composite Wood Deck Stain

One of the best ways to restore your wood’s appearance, or to prevent problems from happening in the first place, is to use a specific composite decking care product.

Using a specific composite wood product will mean it will be sufficiently sealed and protected from weathering whilst also enhancing or reviving the colour of the wood.

One such product is Compo-Care – our water-based composite wood coating that provides a stain-repellent finish with weatherproofing all in just 1 coating. It is available in 2 colours; grey and brown.

Both Compo-Clean and Compo-Care are water-based and as such are safe for the environment.

  1. Hi,
    I tried to order a 5 liter can of Textrol, however, I couldn’t as it appears to be out of stock. I understand stock was due in today.

    1. Hi Ronan,

      Apologies for the delayed reply – somehow your message was not seen.
      We have been chasing for an update in regards to delivery and had hoped to get one this week, but we are still yet to get confirmation.

      Apologies for the inconvenience – hopefully, it won’t be much longer!

      Thank you for your patience,

  2. Can you please give me any tips for cleaning a new composite deck which has been destroyed by plaster stains which I can’t seem to remove

    1. Hi there Ger,

      This is a tricky one to say for certain. If the stain has turned the deck a lighter colour, you could try using Polytrol to restore the pigments that have faded in those areas: – Polytrol works by re-wetting dried out and faded pigments due to weathering and UV rays, so I’m not certain that it would work in this instance – but if you wanted to try it out, we would highly recommend testing it in a small area first.

      Apologies we could not be of more help.

      All the best,
      The Owatrol Team
