When it comes to professional power washing, two key terms often come into play: PSI (Pounds per Square Inch) and GPM (Gallons Per Minute). At Blue Marlin Power Washing, serving La Crosse and Central Wisconsin, we believe in educating our customers about these crucial aspects, as they significantly impact the effectiveness and efficiency of our services.

What is PSI?

PSI stands for Pounds per Square Inch, and it measures the pressure exerted by the water stream. This pressure is what helps break down and remove dirt, grime, and other substances from surfaces. A higher PSI means more power, which can be effective for tougher stains and harder surfaces. However, it’s important to use the right level of PSI for each surface to avoid damage.

Understanding GPM

GPM, or Gallons Per Minute, measures the flow rate of the water. It indicates how much water is being used during the power washing process. A higher GPM means more water is being used, which can be effective for rinsing and removing debris after it’s been loosened by the pressure. It also determines how quickly a job can be completed.

Balancing PSI and GPM

The key to effective power washing lies in balancing PSI and GPM. A high PSI with a low GPM can result in a strong but narrow stream, effective for specific types of stains but potentially damaging or time-consuming over larger areas. Conversely, a high GPM with a lower PSI can cover larger areas more quickly but may not be as effective on tough stains.

At Blue Marlin Power Washing, we carefully select our equipment based on a balance of PSI and GPM that suits the specific needs of each project. This approach ensures that we can tackle any job efficiently without compromising the integrity of the surfaces we’re cleaning.
