We had new paving laid at the back and it seemed like quite a good idea at the time to have quite a light Indian stone. Turns out it properly shows up dirty dog footprints, dirty boot marks, everything really. We put some “Wet and Forget” on it last year and it took away all the green algae that grows on there but after a cold wet winter it definitely needed a jet wash, which we did the other day, and another dose of “Wet and Forget” that I’ll get around to soon.
