What is pressure washing and how does it work?
Pressure washing is a cleaning method that uses a high-pressure stream of water to remove dirt, grime, and other substances from surfaces. It works by using a pump to increase the water pressure from a typical garden hose to a much higher level, usually between 1,000 and 4,000 pounds per square inch (PSI). This high-pressure water is then directed at the surface to be cleaned through a nozzle or spray tip, which helps to concentrate the water stream and increase its cleaning power.
The key to effective pressure washing is the combination of high water pressure and the correct nozzle or spray tip. Different nozzles and tips are designed for specific cleaning tasks, such as wide fan tips for cleaning large surfaces like driveways and sidewalks, and narrower tips for more detailed work like cleaning siding or windows. By choosing the right nozzle and adjusting the pressure setting, you can tailor the cleaning process to the specific surface and substance you are trying to remove, ensuring a safe and effective cleaning experience.
