I've used this product for a while . It certainly removes green algae . For tougher jobs I pressure wash the area first and then apply the cleaner . It certainly cleans and stays clean for months , you've just got to be patient it takes a while to work on stubborn areas. Fades but doesn't remove black spot , but you can buy proper stuff for that.

This stuff is BRILLIANT our block paving looks like new again, it’s so easy to use and when you get to my age ( 70 pluss ) you want things easy, a first class service and a first class product, definitely as good as some twice it’s price. I would recommend this product to anyone, thank you.😊👍⭐️ I would add that our block paving has been laid over 35 years.

A great product which I buy every year . It dilutes to 1 litre of product to 4 litres of water . It goes a long way and is effective for a few months . I don’t even have to apply it with a pump / I use a watering can with a fine rose spout . Moss and green algae disappear over a couple of weeks . For an even better and more long lasting effect I have jet washed the areas in question : allowed to dry and applied this product with great results
