Pressure washing and soft washing are both methods of cleaning exterior surfaces, but they use different techniques and are suitable for different types of surfaces and cleaning tasks.
Pressure washing involves using a high-pressure water stream, usually between 3,000 and 4,000 PSI, to blast away dirt, grime, and other stains from surfaces such as concrete, brick, and wood decks. It is a more aggressive method of cleaning and can be used to remove heavy buildup and stains.
Soft washing, on the other hand, uses a lower-pressure water stream, usually between 500 and 1,200 PSI, and often includes detergents and cleaning solutions. It is a gentler method of cleaning and is often used for delicate surfaces such as roofs and painted surfaces. Soft washing is more effective for removing algae, moss and lichen.
Both pressure washing and soft washing can be effective for cleaning exterior surfaces, but the appropriate method will depend on the type of surface and the level of cleaning that is needed. It is essential to use the right technique to avoid damage to the surface being cleaned.
