Soft vs High-Pressure Washing
"High-Pressure" washing, or power-washing– is the practice of using highly pressurized water to blast dirt buildup off of a surface. This is great for certain durable materials with a rough or textured surface, such as stone, concrete, and other aggregate minerals. However, this can cause serious damage to your siding, trim work, and other parts of your home that require a delicate touch. For common home materials, a soft chemical wash is a much better and more effective alternative. For tough-to-remove, thick buildup, hand scrubbing is an extra careful, thorough way to remove the grime.
