What is pressure washing and how does it work?
Pressure washing is a cleaning process that uses a high-pressure stream of water to remove dirt, grime, and other substances from surfaces. The pressure washer itself is a machine that consists of a pump, a motor, and a hose with a spray nozzle. When the machine is turned on, the pump creates a high-pressure stream of water that is forced through the hose and out of the spray nozzle. This high-pressure stream is what allows for the effective removal of dirt and grime from surfaces.
The key to pressure washing is the combination of high pressure and volume of water. The high pressure allows for the removal of tough dirt and grime, while the volume of water helps to rinse away the dirt and debris. Pressure washing can be used on a variety of surfaces, including driveways, sidewalks, decks, and even buildings.
