Monty Miracle Fast Patio Cleaner - 5 Litre | Outdoor & Garden Surface Cleaner for Patio, Decking, Fencing, Stone, Concrete & Many More | Eliminates Black Spots, Algae, Mold, Lichen in Just 10 Minutes

This product was outstanding, I used it on my very green fences. I followed the instructions and the green disappeared, very effective and also very easy to use.

This is great stuff, works really quickly and better than jet washing. Make sure you wear old clothes when applying, managed to spoil a top with splashes.

it is good but not as good as i had hoped. It is fast but i wouldn't say its cleaned my slabs to like new... once the hose pipe ban is over i will jetwash over them and then maybe the extra clean will bring them up a bit more.

This ain’t to shabby, quick results that you can visibly see.

Just tried the product and found it to work fine, my steps look a lot cleaner after having the builders in plus all the algae has cleaned off, I have a large patio area and the 5 litre bottle didn't cover it so would need to get another bottle so quite expensive, there is a strong smell of bleach and where it has splashed the colour has gone, fortunately I had old clothes on, I think all in all the product would work well in a small area but having to scrub it afterwards with the broom to spread it then rinsing with the hose is a faff I can do without. I will the jet washer out again nearer the summer, it did clean very quickly though and as I used a weed spray it was easy to use.

I’ve got a 5x5 patio yard . Power washed it last week to get it clean and then tried this product to remove what it is supposed up offer. It did nothing.The smell when sprayed is absolutely just like string bleach. That’s it. I bleached my yard. Nothing more. It did not remove a single black spot. The fence, it did nothing for. Apart from being bleach, absolutely waste of my time and my money. I read so much about it, saw videos and etc and thought I’d give it a try. Never again. I’ll stick to power washing and be content with the results. Mediocre product. Don’t waste 30 quid on bleach.

Amazing stuff would highly recommend best patio cleaner ever

I highly recommend this product. It does exactly what it says it does. Use a pump action sprayer with recommended mixture and follow the simple instructions. Warning! wear clothes you don't mind getting white spots on. With the best will in the world you will get tiny bleach spots on them.
