SCRUBB Decking Cleaner is a powerful detergent formulation which cuts through grime, grease and algae to rejuvenate and restore timber decks. Also ideal for use on newly-installed decking to remove pretreatments and prepare the wood for staining or other finishing, increasing the lifetime of the final treatment.

IDEAL USE CASES:

Rejuvenating timber and composite decking:
Removes built-up grime, grease, and algae, restoring decks to their original look.
Cleaning newly installed decking: Prepares fresh timber by stripping away factory pretreatments, ensuring better adhesion for stains and finishes.
Removing stains and contaminants: Lifts bird droppings, dirt, and organic buildup that can make decking look aged and worn.
Ideal for cleaning and maintaining exterior cladding: Use S45 Decking Cleaner to clean composite or timber cladding, ensuring a fresh and well-maintained appearance.

BEST PRACTICE:

Apply before winter: A thorough clean before the colder months can help prevent algae buildup, which can make decking dangerously slippery.
Use in shaded areas: Decking in shaded or damp areas is more prone to algae growth – regular use of S45 Decking Cleaner keeps these surfaces safe and clean.
For heavy staining: Allow up to an additional hour of contact time before rinsing to maximise cleaning power.
Regular maintenance: Using S45 Decking Cleaner as part of a routine cleaning schedule helps keep decking in top condition year-round, preventing long-term buildup of grime and algae.
Test before sealing: If you plan to stain or seal the decking, ensure the surface is thoroughly dry and free of residue after cleaning.

This product is amazing. The decking was slippery and green. Followed the instructions, used a garden spray to apply the product. The results are quite incredible. The grime and dirt washes away.

Bought this for use on composite deck which was installed 2 years ago, has done a brilliant job of removing green algae and general grime that had built up since then, deck looks brand new again.

Was unsure if this was suitable for composite decking so asked the manufacturer for clarification, and was assured it was. My composite decking has been in place for approx. 4.5 years and in that time has built up a level of general grime and detritus. This product was easy to apply using a sprayer, I then worked in using a deck scrub, then after half an hour rinsed everything off with a pressure washer. I am delighted with the results, the decking area looks 100 times better and it took very little effort.

Tried a few different products over the last couple of years but this one works the best. Watering can with rose to put it on. Half an hour to soak with a bit of a scrub with hard sweeping brush and washed off with hose. Perfect job 👍

This product is worth purchasing, in my opinion. I used it and found that if you give it time to work it does draw out the dirt from decking. I’ll get some extra life from the decking as the oil is able to penetrate deeper now and ita looking good.

First time using this and pleasantly surprised. Used my wheel brush for the car and scrubbed each decking board well then pressure washed off. Also just pressure washed one board to see how effective this was. There was a definite difference so happy with the effectiveness of this product.
