TL;DR
Soft washing is the low-pressure cleaning technique in which technicians deliver cleaning chemistry through dedicated pumps and wide-fan tips, dwell it on the surface, then rinse, keeping output well under pressure-washer force. The trade applies it as the standard of care on asphalt shingles, where ARMA, the roofing manufacturers' association, explicitly warns against pressure washing.
