Soft wash
Also called: Low-pressure cleaning
Heard most in: Pressure Washing, Roofing
Cleaning with a solution and low pressure rather than with force, so the chemistry does the work. It is what siding, painted surfaces, screens and roof shingles need, because high pressure on any of them drives water where it should not go or strips the surface outright. Charging the same rate for soft washing as for flat concrete misprices both.
