A pressure washer can be effective in removing algae from concrete surfaces. However, the results may vary depending on the type of algae, the severity of the infestation, and the pressure washer’s PSI (pounds per square inch) and GPM (gallons per minute) ratings.
Algae can be tough to remove, so it’s important to use a nozzle with a higher degree (e.g., 0-degree nozzle) that has a pinpoint spray pattern which focuses the water pressure on a small area. It’s also important to use a cleaning solution specifically designed to remove algae, and apply it before pressure washing.
It’s important to keep in mind that when pressure washing concrete surfaces, it’s best to start with the lowest pressure setting and work your way up, to ensure you don’t damage the concrete. It’s also a good idea to test a small area first to see how the pressure washer affects the surface before proceeding.
How do you pressure wash algae off concrete?
To pressure wash algae off concrete, you can follow these steps:
- Clear the area: Clear the area of any debris, furniture or plants that may be in the way.
- Wet the surface: Wet the surface with a garden hose to prevent the pressure washer from damaging the concrete.
- Apply cleaning solution: Apply an algae-specific cleaning solution to the surface, making sure to cover the entire area. Allow the solution to sit for 10-15 minutes to soften the algae.
- Choose the right nozzle: Use a nozzle with a higher degree (e.g., 0-degree nozzle) that has a pinpoint spray pattern which focuses the water pressure on a small area.
- Start at low pressure: Start at the lowest pressure setting on your pressure washer and work your way up, to ensure you don’t damage the concrete.
- Keep the nozzle moving: Keep the nozzle moving to avoid removing the surface of the concrete.
- Rinse the surface: After cleaning, rinse the surface thoroughly with a garden hose to remove any remaining cleaning solution and debris.
- Repeat if necessary: Repeat the process if needed, until all the algae is removed.
It is important to note that when pressure washing concrete surfaces, it’s best to start with the lowest pressure setting and work your way up, to ensure you don’t damage the concrete. It’s also a good idea to test a small area first to see how the pressure washer affects the surface before proceeding, and always follow the manufacturer’s instructions for your pressure washer and cleaning solutions.

Does pressure washing get rid of algae?
Pressure washing can be effective in removing algae from surfaces like concrete, wood, and brick. The high-pressure water stream can help to break up and remove algae growth. However, the results may vary depending on the type of algae, the severity of the infestation, and the pressure washer’s PSI (pounds per square inch) and GPM (gallons per minute) ratings.
It’s important to use the correct nozzle that has a higher degree and a pinpoint spray pattern, which focuses the water pressure on a small area, and also use a cleaning solution specifically designed to remove algae, and apply it before pressure washing.
It’s also important to note that pressure washing alone may not be enough to completely remove algae, and in some cases, multiple treatments may be required, or even a combination of pressure washing and other methods such as scrubbing, or using chemicals specifically designed to remove the algae.
Additionally, it’s important to keep in mind that when pressure washing surfaces, it’s best to start with the lowest pressure setting and work your way up, to ensure you don’t damage the surface. It’s also a good idea to test a small area first to see how the pressure washer affects the surface before proceeding, and always follow the manufacturer’s instructions for your pressure washer and cleaning solutions.
