Osmo Decking Cleaner is a highly effective concentrated cleaner developed for the regular maintenance of untreated and oiled exterior timber. Its water-soluble formula removes dirt, algae, organic build-up and everyday contamination, helping to keep decking, garden furniture and other outdoor timber looking clean and well maintained.

Easy to dilute and simple to apply, Osmo Decking Cleaner works deep into the timber surface without damaging the wood. Whether you're carrying out routine seasonal maintenance or preparing timber for re-oiling, it's the ideal solution for keeping exterior wood in excellent condition.

Wiltshire Wood Recommendation
We recommend cleaning decking at least once or twice a year to prolong the life of the finish. If the timber has already turned grey through weathering, use Osmo Wood Reviver Power Gel before applying a fresh coat of Osmo Decking Oil.

Suitable For

Timber decking
Garden furniture

Important: Avoid direct contact with ornamental plants and crops. If the timber has already become heavily weathered or grey, Osmo Decking Cleaner will clean the surface but will not restore the original timber colour. For this, use Osmo Wood Reviver Power Gel before refinishing.

How To Use

Remove loose dirt, leaves and debris using a stiff brush or broom.
Dilute Osmo Decking Cleaner according to the level of contamination (typically between 1:25 and 1:1).
Apply the solution and scrub along the direction of the wood grain using an Osmo Decking Cleaning Brush.
For larger areas, use the Osmo Decking & Flooring Cleaning Machine.
Rinse thoroughly with clean water.
Allow the timber to dry fully before applying any Osmo exterior finish.
