Your Pressure Washing Questions Answered
A big part of pressure washing is pressure, and how this pressure is measured uses a scale called PSI, or Pounds per Square Inch. This measurement refers to the pounds of pressure placed on one square inch of the surface being washed, and industrial strength pressure washers can reach as high as 5000 PSI. For a more relatable comparison, your standard hose you’d use for watering the garden or washing the car runs at about 40 PSI, and a light duty consumer pressure washer you may find at the hardware store will tend to be around 1000 and 1200 PSI. Soft washing a home, roof, or other surface will typically use around 1/3 of the amount of pressure as a standard pressure washing, which is around 400 PSI.
What Chemicals Are Used?
Chemicals are typically part of the pressure washing process, just as they’re often part of the process of washing your floors with a cleaner, or your car with a soap. What types of chemicals can vary, however, and if you have a concern about pets or children coming into contact with these chemicals after a pressure washing, there are eco-friendlier and less toxic options to use. Hot washing, or pressure washing with hot water, may even be sought to have a chemical-free or low-chemical option, but it may not be able to eliminate molds or algae as effectively. Speaking with a pressure washing professional can help to clear up any concerns you may have regarding chemical cleanser use and what may be best suited for your home and your family.
How Long Does Pressure Washing Take?
The length of time it takes to finish a job will highly depend on the size of the area and what exactly the home or property owner needs done. For a standard job, however, for a residential home of average size, it will typically take around 1 full day to clean all walls, the roof, and patio areas. More complex jobs will take a bit longer, and smaller homes or properties a bit shorter.
