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)

Well.....how have we just discovered this amazing product ???? We have a lot of fencing around our garden. It was looking very shabby with years of moss & algae built up over 10 years or so. My husband power washed parts over the years but it was both laborious & used gallons of water. It was very messy! We decided to re stain to give it a lift but agreed the algae needed to go beforehand. My husband suggested we power wash...but I decided to have a Google search on suggestions to get rid of algae. Amongst many concoctions of bleach etc. I noticed a spray & leave mould & algae remover. Sounded too good to be true. My husband was very sceptical...said it won't work... I checked on Amazon & found that this particular one was good value in my opinion as it was concentrated. 5litres make 25litres. Coverage 175sqm It was easy to measure out. I litre of pro kleen to 4 litres of water. I put into a spray bottle & was amazed how quickly it covered. Over the next couple of days it was incredible the green algae had completely gone! On one area I did do a second coat as it was so thick...but it got rid of it all. I found when I had an hour or two to spare i just popped out & did a bit more. You need to wear suitable clothing, eye protection & gloves. I did wear a mask as well. Active ingredients. Dimethylbenzyl aluminium chloride Bio degradable formula thats safe when dry. Best to cover plants when spraying. Although the spray literally stays on the fence no dirt ir mess running down to ground. Very toxic to aquatic life !!! Safe for families & pets. Non caustic free of acids & bleach I am so pleased to discover this product. Our fences are looking fabulous now!!! Pros Easy to use. Mess free ..no muddy dirt running on to drive. Good value. Great results with little effort. Cons......🤔... Can't think of any !

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.

Great product easy application with a sprayer killed off all the green algae on on our fences which were quite well covered . Does leave a white residue which i guess is the dead algae which washes off easily with slightly soapy water and a dustpan brush before re painting . would highly recommend this product .

It does actually work, need to leave it on overnight, dosnt work instantly like Hydrochloric acid, isn't as strong but does work, says it makes 25 litres, i sprayed it on as it is

Not bad but had other brands better i feel.

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!

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

Excellent

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

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

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