Concrete sidewalks, walkways, and driveways are often stained by a variety of fluids and markings.  Concrete Driveways often show the same marks, especially if parked vehicles ever drip or leak.

Skid marks from the neighbourhood skateboards and bicycles, sap and other stains from nearby trees and bushes and the occasional motor fluid drippings can all leave your sidewalk unsightly. Clean your sidewalks annually to avoid the build-up of stains and make each successive cleaning easier. Sealing the concrete afterwards is also recommended to protect your sidewalks from weather wear.
