Patio & Driveway Cleaner is excellent, bought the 5L to try 1st and I was pleasantly impressed. So once needed again bought the 20L for value for money. I would definitely recommend and urge people to invest in the product if they have a block paved driveway. A lot easier to maintain its quality look. 2 of my neighbours have asked me how I have kept my driveway so pristine and looking like new, these comments were only asked today as I had used the product again yesterday. I have mentioned to them where I got the cleaner from and they are also looking to purchase this. A+
