Decking Cleaners

Everything needed to clean, rejuvenate, and restore garden decking

Formulated to clean, protect, and revive both softwood and hardwood decking, these garden decking cleaners will remove surface dirt, grime, and grease. Many will treat and remove mould, algae, and lichen and others will help to restore the lost colour of decking boards that have turned grey or silver over time.

We recommend using a decking cleaner on bare or untreated decking as a pre-treatment, before applying a decking preserver, decking oil or decking stain.
