Caring for your Composite Decking

Fitted properly, your new deck should last for decades.  The boards won’t warp or split, they won’t fade or rot and they won’t be damaged by insect or animal activity.

That said, any floor can get pretty messy at times and, being outside, people tend to be less careful with food and drink spills. While the decking will cope with almost everything that gets thrown at it, remember that spills will attract insects; they won’t hurt the boards but it’s no fun being bombarded by wasps or mobbed by ants!  Here’s a guide on how to clear up the most likely messes.

General Maintenance
A soft broom should remove dust, dirt and debris from surrounding trees and plants.  Simply sweep in the direction of the grain.  You might need to give it a wash once a year, especially if plant material settles on it over the winter months.  Use a hose and broom or a pressure washer.

Composite decking has an incredibly tough coating and will resist most scratches.  If one does occur use fine sandpaper (following the woodgrain or grooves) to remove or reduce its appearance.

Oil or Grease
Any oil spills should be cleaned up straightaway to avoid the risk of staining.  Use washing up liquid and rinse away with water.  If it does leave a mark, you can use fine sandpaper to remove it; always go in the direction of the woodgrain or grooves.

Rust marks left by furniture, planters or ornaments can be removed with soapy water and a scouring pad.  In the case of heavy rust use an acidic cleanser or lemon juice and rinse with water.

Wine, Fruit Juice or Coffee
Wipe up immediately using a floor cleaner and water.  Persistent marks can be removed with a light bleach and warm water.

When new there may be some residual tannins (oils) in the wood component of your grooved boards. This tannin may leach out of the board the first few times that the boards get wet and will look like a water stain after the board has dried. This water (tannin) mark can be removed by washing with water - and a stiff brush if required - but it will naturally disappear after the board has been wet/dried several times. It’s more noticeable on lighter colours and more likely to happen on boards and trim that are installed vertically.
