Why Businesses Should Invest in Commercial Pressure Washing

  • Pressure washing (or power washing) uses high-pressure water spray to remove dirt, grime, mold, mud, and loose paint from surfaces like buildings, vehicles, and concrete.

  • The flow rate of a pressure washer is measured in gallons or liters per minute, usually fixed by the pump design.

  • Pressure levels, measured in PSI (pounds per square inch), pascals, or bar, can range from 750 to 30,000 PSI depending on the machine and are adjustable using valves or nozzles.

  • The terms pressure washing and power washing are often used interchangeably, though some distinguish them by whether hot water is used.

  • An industrial surface cleaner uses rotating high-pressure jets to clean flat surfaces evenly and quickly

  • Some surface cleaners have wheeled circular shrouds to protect users from splashback and debris during operation.

  • Hydro-jet cleaning is a more powerful version of power washing, ideal for removing heavy debris and buildup in tanks and pipelines.

  • Pressure washing is used to improve aesthetics, reduce hazards, and eliminate allergens in both residential and commercial environments.

  • Residential uses include cleaning gutters, roofs, decks, siding, paved areas, and windows.

  • Commercial applications include cleaning large structures like office buildings, churches, schools, and hospitals.

  • There are two main types of pressure washers: hot water and cold water models, each suited for different tasks.

  • Hot water pressure washers are ideal for removing grease and oil from concrete, such as in parking garages, gas stations, and drive-thrus.

  • Cold water pressure washers are commonly used for general residential cleaning jobs.

  • Surface cleaners help clean large flat areas more efficiently, using dual rotating jets and a disc-shaped cover to limit noise and splashback.

  • Some surface cleaner models use castors or plastic bristles to maintain even spacing and ease of use on various surfaces.


  • Pressure washer nozzles adjust the spray direction and intensity, affecting cleaning distance and impact.

  • Nozzles are color-coded: red (0°) for narrow, powerful streams, and black (65°) for wide, low-pressure coverage.

  • High-pressure water jetting or hydrojetting reaches up to 20,000 PSI, making it suitable for industrial cleaning and material cutting.

  • Hydrojetting is used in industries like oil and gas to clean equipment with minimal environmental impact and reduced fire risk.

  • The technology is effective both above and below water, removing coatings, corrosion, scale, biological fouling, and insoluble substances without damaging the base material.
