Our dual action, advanced formula Decking Cleaner provides highly effective results for cleaning & reviving decking, sheds, and fences. It cleans and revives the wood, restoring it to its original colour.

The Decking Cleaner can also be applied directly to wooden surfaces with no scrubbing required to kill green algae, lichen, mould and moss.

If you are planning to apply a stain or oil to your timber, be sure to clean it first with the Decking Cleaner to open up the pores of the wood and improve the absorption of any oil or stain.

Suitable For

Decking Cleaner is suitable for all types of exterior wooden decking, fences and sheds.  

Coverage & Shelf Life

5 litres of Decking Cleaner is enough to clean roughly 25m² of decking.

Store in a cool, dry place, away from direct sunlight.


Using a hosepipe, slightly dampen the wood to be treated. Pour the product into a watering can and pour over the timber. Scrub with a stiff bristled brush and leave for 20 minutes for the cleaner to take effect. Alternatively, pour the product into a bucket and apply to the wood using a scrubbing brush. Rinse with a hosepipe to wash off all dirt and residue from the cleaner. Some green staining may still be visible at this point; follow the instructions for killing algae & lichen as a final step.



Simply pour or spray onto effected areas, making sure to saturate the wood and leave it for 2 – 3 days. The green colour will start to fade in this time and will kill the algae. Then simply brush away any dust which is left behind.
