We did a little driveway clean and seal, something we'd put off for a while and mate did it need a clean!! We used Slurry Solutions to clean all the stains out of the concrete and sandstone. To do this in the past we probably would have used a hard acid but SlurrySafe is actually just as effective and biodegradable. Being in the building industry it really excites us to see effective environmentally friendly products being used. So if you need to clean some concrete, stone, bricks or even clean the concrete off your tools you should definitely be using SlurrySafe!
