Pro-Kleen MY16 Patio Cleaner Simply Spray and Walk Away Green Mould and Algae Killer for Patios, Fencing and Decking 5 Litre Concentrate (Makes 25 litres)

This is my second purchase of this brilliant stuff - just dilute & throw over the decking, it then just does its stuff & my decking is no longer slippy!

I used this patio and walkway cleaner on a fairly large area and was honestly surprised at how well it worked. As you can see from the photos, it made a noticeable difference to the paving after just one application. At first I tried applying it with a small hand spray bottle, but for the size of the area I was covering it quickly became quite hard work. I ended up switching to a low-pressure garden sprayer so I could properly saturate the surface, which made the job much easier and ensured an even application. After about 24 hours the results were already very visible. Most of the green algae and grime had disappeared and the slabs looked much cleaner. There is still a slight bit of green residue in a few places, so it may benefit from a second spray or possibly a good rinse with a hose to finish it off. Overall though, it worked better than I expected and was very easy to apply once I used the right sprayer. Definitely a worthwhile product if you’re trying to freshen up a patio or walkway without heavy scrubbing or pressure washing.

Really happy with this. Easy to mix and apply. Pictures show before and after in just 24 hours. Great stuff!

Excellent. Within hours of spraying my decking and paving slabs , the results were noticeable. The following day - no more green. It was recommended by a friend of my partner, and I was hit and miss wether it would work. No damage to my paint work either. It is a bit expensive , but I work it out at 5 litres will do me 5 years.. therefore £3 ish per year - that's a bargin. Just Spray and forget. Buy it ... You wont be disappointed. However, it wont dissolve or remove dirt, so you will still need to pressure wash, or brush/scrub general dust/dirt away. Big thumbs up ! !

Not sure what to make so I have attached pics. First of all it says not to put on wet wood etc so I waited for the fence to completely dry as we sprayed the fence a few days prior to treatment to get rid of cobwebs etc. I wouldn’t say it’s amazing but it did work and I went over this 3 times waiting for each time to dry. I used a small Handheld jet wash that is quite powerful, I’ve read someone painted it on with a paintbrush and they left some photos so I think that in my opinion would be better but as you can see it has removed a lot of algae so I would say it’s effective maybe it would work even better with a stronger jetwash.

Brilliant I sprayed my fence and deck last Sunday it was a lovely sunny day. Since then we've had rain, hail and frost. As you can see from the photos the deck is still a bit green but it hasn't really dried out. And the instructions do say to avoid spraying if rain is expected and to use it on a dry surface. My fence is looking really great. I took the second set of photos a week later at about the same time of day and on the Sunday. We had yet again another rain shower earlier so I still haven't been able to spray a second time. I was unsure about how much I would need to use so I measured out a smaller amount of 500ml mixed with 2 l of water so I had 2.5 l instead of the 1l with 4l of water. But used that up on the decking and part of the fence. And ended up mixing up the same again.

I purchased this to clean slabs and concrete around the garden, A few days before applying the Pro-Kleen a full jet wash of the paving was undertaken to remove any dirt and surface algae. A few days later on an entirely dry day the product was applied with a garden sprayer as per manufacturers instructions. A small area was not treated as there was not enough chemical to complete the entire garden. It has now been a couple of weeks since applying and the only difference is some of the green algae and moss has slightly reduced but no change at all to the black spots of mould compared with the untreated area.. UPDATE: After several months I have noticed a lot of the black mould has significantly reduced. It seems this product does work on the mould but it takes time. I have now revised my score from 1 to 4 stars and would use this again

Was a bit sceptical but had good reviews so decided al give it a go ! Pics show stages before, applied and a few days later sorry it’s raining in last pic so looks wet still. Did take about 2 days to start seeing a difference but definitely killed the green off I just need a nice day to give them a quick clean and will be spot on !

Signori....il prodotto funziona ! Provato sul mio patio di ca 200 mq fatto in mattoni , e' sparita ogni traccia di muschi e licheni. Bisogna avere pazienza , ed aspettare qualche giorno : anche se sembra che continui a fare effetto anche dopo. Dopo 10 giorni di pioggia continua, avevo il patio in pessime condizioni , oltre tutto molto pericoloso, si incominciava a scivolare , negli anni passati risolvevo il problema passando della varecchina ( ipoclorito di sodio ) quasi senza diluirla..... poi grazie ad Amazon , ho trovato questo prodotto , anche se avevo letto molte recensioni , rimanevo scettico,invece il prodotto e' " magico " ! Consiglio questo prodotto !! Io intanto ne comprero' un'altra confezione....( non ho ancora finito ) Grazie Amazon per avermi aiutato a risolvere un grosso problema ! Ciao a tutti , Giancarlo

sicuramente potrebbe funzionare .... ma non spruzzandolo e basta. Proverò a spazzolare

E' abbastanza buono ma non è duraturo nel tempo come me lo sarei aaspettavo visto che è concentrato

Lo dato su del muschi sopra una strada in salita, dopo circa una settimane h iniziato a diventare marrone e a morire
