Decking Cleaners

Formulated to clean, protect and revive both softwood and hardwood decking, these garden decking cleaners can remove mould, algae and lichen, restore grey weathered decking or simply clean surface dirt and grease.

Many of these decking cleaners can also be used on bare or untreated decking as a pre-treatment before applying a decking preserver, decking oil or decking stain.
