This article provides step-by-step instructions on how to effectively pressure wash concrete driveways and sidewalks. It emphasizes the correct techniques and equipment needed to achieve super clean results as a DIY project.

To begin, it is essential to gather the necessary equipment. You will need a pressure washer with a minimum PSI of 3,000 and a flow rate of at least 4 gallons per minute. Additionally, obtain a surface cleaner attachment, which helps to evenly distribute the water pressure and avoid streaks. Safety gear such as gloves, goggles, and closed-toe shoes are also recommended.

Before starting, make sure to clear the area of any loose debris, such as leaves or dirt. It is advantageous to wet the area first, as this helps to prevent the concrete from absorbing the cleaning solution too quickly. Next, mix a concrete cleaner or degreaser according to the provided instructions. Pour the solution into the pressure washer’s chemical injector or detergent tank.

Now, it’s time to start pressure washing. Begin by applying the solution to a small, inconspicuous area of the driveway or sidewalk to test the strength and ensure it does not cause any damage. Once confirmed, position yourself at one end of the surface and move the pressure washer in a straight line, overlapping each pass by about 50%.

While pressure washing, maintain a steady pace to avoid uneven cleaning. The surface cleaner attachment helps by evenly distributing the water pressure, allowing for a more uniform and consistent clean. Be cautious not to focus the pressure washer on one spot for too long, as this can cause damage.

After completing the initial cleaning, it is important to rinse the area thoroughly. Hold the pressure washer nozzle at a 45-degree angle and gradually flush away the detergent, ensuring the entire surface is covered. Pay extra attention to any areas with stubborn stains. For particularly tough stains, brushing with a stiff-bristle brush can help loosen the dirt.

Once rinsing is complete, allow the driveway or sidewalk to dry for at least 24 hours before using it again. This waiting period is important to ensure that the concrete is completely dry and ready for foot or vehicle traffic.
