When it comes to cleaning composite decking, our expert advice is to treat the composite deck like you would treat linoleum flooring. You can easily clean composite decking with a soft brush, water, and a mild detergent. Once you’ve scrubbed the composite decking boards, be sure to rinse the deck well to remove all of the soap.
5 Composite decking cleaning tips
- Always clear the composite decking of any debris such as leaves or dirt before beginning the cleaning process.
- Do not use household bleach to clean your composite decking. Use a sodium percarbonate based cleaner to clean composite decking as it is an environmentally-friendly bleach agent and able to clean a range of bacteria from fungi to mildew.
- Dissolve 50-60g of the cleaner per litre into warm water and apply to the composite decking surface a section at a time for around 30-60 minutes (longer for stubborn stains) before scrubbing with a soft-bristled brush.
- Rinse off the solution with clean, fresh water and never use a pressure washer on composite decking as it can cause the outer layer to ‘etch’ off leading to chipping, risk of sun damage, or mould. We would only recommend using a jet wash when using the fan shaped nosel and on a low psi. We would recommend jet washing your composite decking twice a year,extra care is needed for lighter colours like Ash and graphite in the Clarity composite decking range.
