Pressure washing uses high-pressure water (typically 1,300+ PSI) to physically blast dirt and grime off hard surfaces. Soft washing uses low-pressure water (around 100–500 PSI) combined with safe cleaning solutions that do the work chemically. Pressure washing is great for concrete, brick, and other tough surfaces. Soft washing is the right call for siding, roofs, painted surfaces, and anywhere high pressure could cause damage. We use both — the trick is knowing which one your specific job needs.
