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)

The Pro-Kleen MY16 Patio Cleaner is an absolute game changer for outdoor cleaning. True to its “spray and walk away” promise, it requires minimal effort and delivers impressive results over time. I used it on my patio where green algae and mould had built up, and within days I could see a noticeable difference. It continues to work gradually, leaving surfaces looking much cleaner without the need for scrubbing or pressure washing. It’s really easy to apply, covers a good area, and saves a lot of time compared to traditional cleaning methods. Perfect for patios, driveways, and other outdoor surfaces. Excellent value for money and incredibly convenient—definitely a 5 out of 5!

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.

Cleaned the moss off really good

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 !

Not bad but had other brands better i feel.

This is a concentrated product. Just follow the dilution instructions as closely as you can, don't over dilute it and only apply it when no rain has just fallen and no further rain is likely for 6 hours. It would be best not to apply it in full sun on a warm day or it will dry too quickly before being absorbed by the plant life you are trying to kill. I used it in late January to kill moss and green algae on my block-paver driveway, applying it with a watering bar on a watering can . No rain fell for several days and after about a week the moss turned brown and the green alga disappeared . A month later, the moss looks completely dead and just needs scraping out. I expect that the moss will regrow from its spores later, it always happens, - all the products I've ever used kill the plant but not the spores. ProKleen is well priced , does the job and is very economical . Just follow the instructions carefully .

Pretty good results with following instructions. Took a couple of days for a decent result, doesn't go as far I don't think as suggested but top marks for ease of use. I was concerned about it drying in time before letting the dog out & a couple of areas had to be redone but in general a decent product

This stuff is absolute magic! Had a very green patio, followed the instructions and applied with a watering can. Within 24h the algae had completely disappeared and I was left with a very clean patio with NO effort!!

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
