  • Start using the pressure washer from the highest point and make your way down while cleaning it.
  • Keep the want at least 12 to 15 inches away from the surface. Getting too close to the surface can damage it.
  • Keep a steady hand when using the pressure washer and move back and forth across the concrete.

  • Use warm or hot water if possible.

Safety Precautions

Cleaning with a pressure washer is a dangerous task, and it can be easily understood by the fact that about 400 psi pressure is considered dangerous for humans, and the pressure washer has a pressure of 3000 psi. These are the safety precautions that must be followed before using the pressure washer to clean the concrete

  • Never use the pressure washer without the water
  • Do not run the pressure washer in stand by position for too long (power is on, but water is not discharging)

  • Use the wheel-mounted cleaner to clean the surface in less time and energy.
  • Use the hot water pressure washer cleaner, increasing the dirt removal rate.
  • Use some concrete cleaner and degrease before cleaning to achieve the best cleaning effects.


Final Thoughts

Concrete cleaning requires a high rate of water and a high power pressure washer. It is a tricky job that requires many skills and safety precautions. With proper techniques and tricks, you can clean the concrete surfaces with better efficiency and in less time.
