Two of the most common exterior cleaning methods, soft washing and pressure washing, are often confused. Choosing the wrong one for your surface can damage siding, strip paint, or fail to properly clean organic growth. Here's how to tell them apart and when each is appropriate.

What Is Soft Washing?
Soft washing uses very low water pressure (similar to a garden hose) combined with biodegradable cleaning solutions to kill and remove organic growth, mold, mildew, algae, and bacteria, from surfaces. The chemical solution does the cleaning work, not the pressure. This makes it ideal for surfaces that can't handle high-pressure water impact.
What Is Pressure Washing?
Pressure washing uses high-pressure water (typically 1,500–4,000 PSI) to physically blast dirt, grime, oil stains, and debris from hard surfaces. The force of the water does most of the cleaning. No chemicals are needed for many applications, though detergents are sometimes added for enhanced cleaning of tough stains.

Which Surface Needs Which Method?
Soft washing is correct for: vinyl siding, painted wood siding, stucco, cedar shake, roof surfaces, and screen enclosures, any surface where high pressure could cause physical damage, water infiltration, or paint removal. Pressure washing is correct for: concrete driveways and walkways, brick, interlocking stone, pool decks, and other hard impervious surfaces that benefit from the force of high-pressure water.
Safety Considerations
High-pressure washing on the wrong surface causes real damage: blown-in water behind vinyl siding, stripped mortar from brick, splintered wood, and voided paint warranties. Soft washing, if done with incorrect chemical concentrations, can bleach plants, damage seals, or leave residue. Professional application of both methods requires training and experience to avoid these pitfalls.
