We only pressure wash every 3-4 years since using this as it keeps the lichen and algae away. We used it 3 years ago on garden shed roofs and haven’t had to repeat it since. It killed all the moss and we just had to sweep it off after about 3 weeks (when the weather improved). We are surrounded by mature trees and woodland and what a difference it makes.We recommend it to everyone and they see the difference very quickly in their gardens and buildings too. We’ve used the dilute yourself as well as the ‘as it comes’ with the same results. It’s 100% effective in a very short period of time. We used it on the top of a decorative wall and the algae was gone in 3 days.I do like to pressure wash - I find it very therapeutic but I do give in around the end of March and feel I’m cheating with Spear & Jackson 😀"},{"@type":"Review","reviewRating":{"@type":"Rating","ratingValue":"4.0"},"author":{"@type":"Person","name":"J***N"},"datePublished":"1 April 2025","name":"Does the job","reviewBody":"Obviously I think that this product works as I have bought it more than once. Although 5 litres may not sound much it does require diluting 4:1 and actually makes 25 litres which will treat a substantial area. It's simple to use with a garden sprayer and simply needs to be sprayed over the area that you need to clean. It works progressively and gradually, but quite quickly, cleans the area and keeps working for months. There are other brands that do a similar thing but I suspect they all use the same chemical (which is child and pet friendly) but tend to cost more (a lot more in some cases). This product does all I ask at a reasonable price."},{"@type":"Review","reviewRating":{"@type":"Rating","ratingValue":"5.0"},"author":{"@type":"Person","name":"B***S"},"datePublished":"17 May 2025","name":"Patio and fence cleaner.","reviewBody":"Used on my garden fence and worked really well.
