I used this surface cleaner to remove algae build-up on canvas that was in lake water as a walking surface. I had originally thought the pressure sprayer would remove the algae quickly just light sweeping. I was so wrong. Using the surface cleaner, the job went right along and did a good job.
This product made an immediate improvement on out concrete. Without any detergent or prior preparation the surface cleaner stripped off much of the dirt and grime from our sidewalk and patio.
