The terms "power washing" and "pressure washing" are often used interchangeably, and there is a lot of overlap between the two processes. Both methods involve using pressurized water to clean surfaces, and the equipment used for both is quite similar. However, there is a subtle difference between the two:
Pressure Washing: Pressure washing is the more commonly used term. It refers to the process of using high-pressure water to clean surfaces. Pressure washers are machines that use a motor or engine to increase the water pressure significantly and expel it through a nozzle. The pressure generated is measured in pounds per square inch (psi). Pressure washing is excellent for removing loose paint, mold, grime, dirt, and other contaminants from surfaces like concrete, brick, wood decks, and fences.
Power Washing: Power washing is a specific type of pressure washing. The key difference is that power washing uses heated water in addition to high-pressure water. The water is heated using a built-in heating element, making it more effective for tackling tougher stains, grease, and oil. The combination of hot water and high pressure makes power washing more suitable for removing substances that are more stubborn or require some heat to break down effectively.
In summary, the main difference between power washing and pressure washing lies in the use of heated water. Pressure washing uses regular, unheated water at high pressure, while power washing uses heated water at high pressure. The choice between the two methods depends on the specific cleaning task at hand. Pressure washing is generally sufficient for most common outdoor cleaning jobs, while power washing is more appropriate for surfaces with heavy oil, grease, or stubborn stains. However, it's essential to use the appropriate equipment and techniques to avoid damaging delicate surfaces with either method.
