How to Pressure Wash Driveways or Concrete

There are many reasons for wanting to pressure wash your driveway. Perhaps your neighbor just got theirs done, and now it looks simply wonderful? Or maybe,without spending 10,000 dollars, you want to boost the attraction of your home? Or it just could be that every time you pull up your vehicle it annoys you. Whatever the reason, here are the seven steps for pressure washing your driveway, or really any concrete surface. 


  1. Clear the area 

    1. While it seems obvious enough, it seems apparent but must be said: clear the space of children's toys, cars and other things that could hamper the washing of the driveway. 

  2. Prepare the power washer and driveway

    1. Get your power washer ready by attaching the garden hose and the 25-degree nozzle. Now turn it on and give your driveway a once over to remove loose debris like pebbles, grass and any small tree leaves or branches.

  3. Add detergent

    1. It is now time to use detergent. Be sure to read your machine’s guide to understand which driveway cleaners are recommended for your specific pressure washing machine. At this point, also make sure that the nozzle is attached properly. The soaking nozzle should be attached, which intended to flood the driveway instead of blasting it clean, at least at this point. 

  4. Let is soak 

    1. Let the detergent soak into the driveway, after spraying. You will need to wait about 5 mins, to make sure that the detergent is actively there. By letting the detergent sit for a moment, it is letting it soak into the grime and stains, much like dishes in the sink. This way, when you go to use the pressure washer to blast, the detergent has already softened the spots and allows them to be taken away at a more rapid pace. 

  5. Blasting time!

    1. The detergent is now prepared to blast off all the spots, tough stains, mildew and other debris. The suggested technique is a surface cleaner attachment. A surface cleaner attachment will act quicker, and finish cleaning the best, since it scatters water across a wider surface, which decreases the likelihood of  harming the concrete. It will also push the flow more rapidly, which allows it to "tear" dirt and grime from the surface. The surface cleaner can cost between $20 and $2000 depending on size and material (plastic or stainless steel).. 

  6. Rotary Nozzle

    1. Much like a surface cleaner, a rotary nozzle does something comparable to the water flow. It pulses / turns the water flow to push the dirt even further away and really peel the surface. Use this nozzle to remove the stain and dirt from very fragile regions.

  7. Rinse and done! 

    1. The surface should be smooth and clean now. The detergent should now be prepared to be rinsed away during the final rinse. Put on the 25-degree pin and rinse carefully. 

As always, make sure to practice safe pressure washing techniques. Safety is very important, and pressure washers can be dangerous if not handled properly. Read the pressure washer guide at all times to learn how to use it correctly, and to understand what chemicals in a detergent tank are secure to use.
