It opens the pores of the wood so your oil or stain will adhere and leave you with a longer lasting finish. Brings your wood back to its natural appearance Cleans and revives weathered decking Can act as a general cleaner to brighten decking Removes mould and algae Fast acting – you don’t have to wait to start cleaning Suitable for all types of decking Helps your oil or stain last longer Can be used over oil or stain Application Be careful! Your decking might become slippery during cleaning. Pour the Decking Cleaner & Reviver directly onto your decking. Use a stiff brush and scrub the surface. Leave it alone for 15-20 minutes. Use a pressure washer to wash off the cleaner and remove dirt. Work from one end of a decking board to the other in one continuous motion. If you don’t have a pressure washer, scrub the surface with a stiff brush and hose it down. Make sure you remove all cleaning residue for the best results. Review: Great product! - Great product. Found with a bit of scrubbing that the surfaces came up really well. Used it not only on my decking but also on my wooden gate before painting. Did a great job of removing all the algae and growth leaving the surface ready to paint once it was rinsed. Review: Helps lift grime but might take longer to work on wood that’s gone green. - My deck had been treated with a wood preserver/oil that had weathered off and so the deck started to go green and had a dirty/black appearance. Sanding the step first of all didn’t remove the green but did the black. It then occurred to me to look for a biocide that could do the work for me. I have included a before photo, during and one after two treatments and three coats of decking preserver. I applied as per the instructions and used a stiff brush to work it in. After one treatment the gunge really started to lift (please see photo), however it is hard to say how much of the work was done by the jet wash, so my advice would be to try cleaning with that first, as although I’m very pleased with the final result (shown in photo with two coats of decking preserver reapplied), this solution didn’t get rid of the green parts of the wood as much as I’d have liked (but it does dry lighter so doesn’t look too bad). Conclusion - for the price, worth a shot, but maybe try giving your deck a jet wash first to see if that is sufficient. Update: I’ve noticed the greener parts of the wood have almost gone so wonder if this product continued to work in the days and weeks after use? Fundamentally, after taking the steps I took to restore this deck, I am pleased with the end result. ## Features - Causes serious eye irritation. - Contains 2,2',2"-(hexahydro-1,3,5-triazine-1,3,5-triyl)triethanol and 1, 2-benzisothiazol-3(2H)-one.

We used as instructed (making sure to leave on for a while then scrub) then washed off and the cedar wood came up a treat. Waited for it to dry out then treated with oil. Looks lovely again. ## Frequently Bought Together - Ronseal DC Decking Cleaner 5 Litre - Ultimate Decking Oil Natural 5L [37297] - 7" Decking Paint Brush Deck Stain Applicator with 60" Long Handle, 3" Paint Brush Included for Woodstains, Oils, Deck Coatings, Fence Wall Furniture --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/49141570-ronseal-dc-decking-cleaner-5-litre](https://www.desertcart.pt/products/49141570-ronseal-dc-decking-cleaner-5-litre) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-07-12*
