Ronseal DC Decking Cleaner 5 Litre

Does what it says in the tin. Quality is good and ideal to get rid of mould built up during wet weather.

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.

I tried power washing my decking with no success. Bought this, used a hard brush to get right into the wood. Left it overnight. Gave it another light scrub on the morning then power washed off. It's a great product when coupled with power washing.

Brought this to clean decking . My decking had old decking stain on it plus green allege. Brushed it on left it for 20 minutes. Then jet washed it off . Really good for the money 👍👍

okay but nothing brilliant

It cleaned the decking really well, just follow the instructions and it will make the wood look almost new

This product worked very well on our old deck that hadn’t been looked after by previous owners. Although it does need a stiff brush on your hands and knees, left to soak for 10 mins or so before blasting with a pressure washer for desired effect. Anything less will not really do the job on a heavily soiled deck. Best result is to pour some into a bucket and scrub rather than pour directly onto the decking as the instructions suggest, as this is not a quick job. Beware it does become very slippery underfoot, like a slip n slide!

Cleaned the decking.

ho preso questo prodotto perche speravo di risolvere un annoso problema della pulizia del pavimento esterno prima di dare il trattamento protettivo (legno ingrigito), ho seguito le indicazioni, spruzzato, strofinato con spazzolone, lasciato agire 20 minuti, risciacquo con idropulitrice e niente... il legno grigio come prima! allora lo spruzzo di nuovo e lo lascio agire per un giorno sperando che sciogliesse lo sporco togliendo la patina grigia ma nulla! inoltre fa un sacco di schiuma quindi ho dovuto passare 4-5 volte l'idropulitrice per eliminarla ed ancora se ci spruzzo esce schiuma bianca! per pulirlo devo quindi fare come sempre ovvero passare il getto vicino in modo da rimuovere il grigio e poi levigare perche si aprono i pori ed infine dare il protettivo.prodotto inutile!
