Make a solution of one part white distilled vinegar to two parts water. However much solution you require will depend on the amount of ground that needs sanitation.
Pour the solution over the ground that requires sanitizing, such as a driveway, parking lot, garage floor, brick or concrete walkways or stepping stones. If sanitizing stepping stones or other walkways that are surrounded by grass, dip a rag in the solution to prevent the vinegar from killing the grass.
Do not wipe up the solution. Repeat Steps 1 and 2 as needed depending on the amount of ground requiring sanitation as well as the severity of the ground's condition.
