The difference between Pressure Washing and Soft Washing

Pressure washing and soft washing are both methods used to clean exterior surfaces, but they differ in the type of equipment and techniques used.
Pressure washing, also known as power washing, uses high-pressure water to blast away dirt and grime. A pressure washer is a machine that uses a pump to increase the water pressure and nozzle to direct the water to the surface. The water pressure generated by the machine can reach up to 4000 PSI (pounds per square inch) and it is used to clean surfaces such as driveways, decks, sidewalks, and buildings. Because of the high pressure, it can clean surfaces quickly but also can damage delicate surfaces, or even strip paint or damage wood.
On the other hand, Soft washing is a cleaning method that uses low pressure and specialized cleaning solutions to clean and disinfect surfaces. A soft washing system uses a low-pressure sprayer to apply a cleaning solution that is specifically designed to target the type of stains and buildup present on the surface. The cleaning solution is then left to dwell on the surface for a period of time before being rinsed off with low-pressure water. Soft washing is a gentler method of cleaning compared to pressure washing, making it ideal for delicate surfaces such as roofs and painted surfaces. It is also effective in cleaning and removing algae, moss, lichen and other microorganisms that grow on the surfaces.
In short, pressure washing is a method that uses high-pressure water to clean surfaces quickly, while soft washing is a method that uses low-pressure water and specialized cleaning solutions to clean and disinfect surfaces gently.
