TL;DR
A soft wash is an exterior cleaning treatment that applies a biocidal detergent solution, usually sodium hypochlorite with surfactants, at garden-hose pressures below about 500 PSI, letting chemistry rather than force remove organic staining. It is the appropriate method for roofs, vinyl and wood siding, stucco, and screens, where high pressure would strip granules, force water behind cladding, or tear material.
What it means
A soft wash is an exterior cleaning treatment that applies a biocidal detergent solution, usually sodium hypochlorite with surfactants, at garden-hose pressures below about 500 PSI, letting chemistry rather than force remove organic staining. It is the appropriate method for roofs, vinyl and wood siding, stucco, and screens, where high pressure would strip granules, force water behind cladding, or tear material. Results last longer than pressure cleaning because the organisms are killed, not just decapitated.
