The Best Way to Clean a Concrete Driveway with a Pressure Washer

Are you concerned about the ugly stains you see on your concrete driveway? Concrete stains, such as oil stains, are unsightly and can degrade the surface of your driveway. Pollen and filth can also adhere to the concrete, just like they can to your home siding, roof and patio furniture.

The concrete can begin to disintegrate if it is not treated. So, if your concrete driveway looks a little forlorn or there are stains on your brick sidewalks, it’s time to stop ignoring them and start cleaning. Besides, a tidy driveway also increases kerb appeal.

The simplest and best way to clean a concrete driveway is with a pressure washer, but it must be done correctly. In this blog, you’ll learn about using water pressure to clean a concrete driveway properly to keep your outdoor space looking great and in excellent condition.

Preparing your driveway for pressure washing

What is the best pressure washer to clean concrete? You can use either electric and gas pressure washers to clean your driveway and other concrete or brick surfaces. These pressure washers use a garden hose to deliver water. The water pump within the pressure washer is powered by the engine, which pressurises the water to come out with more force than a typical garden hose.

But before you start your concrete pressure cleaning task, do the following things first:

  • Sweep away any loose dirt and debris with a broom.
  • Check your driveway-facing doors, walls, and windows once the road is clear of debris.
  • Cover those openings with plastic sheets or a tarp and secure them with painter’s tape.

Taking these preliminary steps will prevent these areas from being mistakenly sprayed. Why? Well, subjecting them to power washing will cause the painted surfaces to start to flake away. Covering them will also protect them against any flying debris that may have been missed during the initial clean-up.

Also, since pressure washers come in a range of models and brands, always consult the device’s instructions and safety manual. The manual will walk you through every step of using your pressure washer safely and effectively.

One last point before you start pressure washing — make sure you know the highest point of your driveway and the direction of the natural flow of water to make cleaning easier and faster.

Steps in pressure washing

Here are the steps to get the best results when you use a high-pressure washer for cleaning a concrete driveway:

  • Step 1 Clear the area of children’s toys, bicycles, cars and anything that could obstruct pressure washing. 
  • Step 2 — Connect the garden hose to the 25-degree nozzle to get your cleaner ready. Turn it on and sweep your driveway to remove any loose or leftover debris, such as pebbles, grass, twigs, branches, or small tree leaves.
  • Step 3 — It is now time to use the detergent. We assume that you’ve read the manual to find out which driveway cleaners and degreasers are approved for your specific brand (or model) of washer. At this point, you should also attach the low-pressure soaping nozzle to your sprayer. Instead of scrubbing the driveway, the soaping nozzle is designed to saturate it.
  • Step 4: Allow 5 minutes for the cleaning solution to work its way in to the surface dirt of the driveway before performing the necessary pressure wash.
  • Step 5 — With driveway stains, thick filth, mildew and other dirt already broken down by the detergent, you can now start blasting them away. If you have a surface cleaner attachment, use it with the pressure washer. It works by helping to disperse the water over a larger area, so you clean faster and more efficiently. It also lowers the risk of concrete damage from using direct high pressure while also pulsing the water flow to detach the dirt and grime from the surface.
  • Step 6 — For tougher stains and filth, use a rotary nozzle. It pulses and rotates the water flow to push and scrape dirt and grime off the surface more effectively.
  • Step 7 — The driveway should be free of debris and dirt at this stage. It’s time for the last rinse to obliterate the detergent. With the 25-degree nozzle attached to the spray wand, give your concrete driveway one final rinse.
