The terms “pressure washing” and “power washing” are interchangeable, referring to the same method of cleaning an exterior object with water. While the general term is broad and can be applied to various surfaces, it’s important to note that different surfaces require different methods of cleaning. True professionals know the various ways to pressure wash an object, while fly-by-night companies may not. Additionally, most surfaces actually need to be “soft washed” rather than “pressure washed,” as soft washing uses less than 1,000 psi and is less likely to cause damage. Unfortunately, amateurs often make the mistake of pressure washing when they should be soft washing, leading to property damage.
