Depending on the type of concrete used and the size of the sidewalk it will take anywhere from 24-72 hours before it can be walked on. The edges of driveways that will bear more weight may need longer.

Step two. With the cleaner I used, you donât want your sidewalk to be soaking wet, only lightly wet when you apply the cleaner. Let your sidewalk dry for a bit, and mix up your cleaner. The cleaner must be used within an hour of mixing it, so donât mix it until right before you are ready to use it. I filled up my tank sprayer with two gallons of hot water (hot water is recommended) and added in eight capfuls of the foaming cleaner.
