Question

What is the most effective way to remove old gum from concrete stairs and sidewalks?


Answer

Use a pressure washer with a narrow fan spray tip. The hot water from a 1200 to 1500 psi truckmount pump works well. Get the right angle, and the hot spray will quickly peel the gum off the walkway.
