TL;DR
Sodium hypochlorite solution is liquid chlorine bleach, NaOCl in water, sold for exterior cleaning at 10 to 12.5 percent concentration versus the 5-6 percent of household bleach. It is the active biocide in soft washing, killing algae, mildew, moss, and bacteria on siding and roofs rather than merely blasting the stains off.
What it means
Sodium hypochlorite solution is liquid chlorine bleach, NaOCl in water, sold for exterior cleaning at 10 to 12.5 percent concentration versus the 5-6 percent of household bleach. It is the active biocide in soft washing, killing algae, mildew, moss, and bacteria on siding and roofs rather than merely blasting the stains off. Handling requires gloves, eye protection, and care around metals and landscaping, and it degrades quickly in heat and sunlight, so contractors buy it fresh.
