Sodium Hypochlorite vs. Eco-Friendly Cleaners in Myrtle Beach, SC — what this page covers
Greenwashing is common in this industry. What matters is that the organism dies and runoff is controlled. Ask what percentage they use and how they manage runoff.
The key points
Sodium hypochlorite (diluted, with surfactants) is the industry standard for killing mildew and algae at the root
Eco-friendly/organic cleaners work on light surface grime but rarely kill the organism — mildew returns fast in beach humidity
The environmental risk is in the RINSING, not the chemistry: runoff must be managed away from plantings and drains
SH at washing strength (1–2%) is far weaker than household bleach (5–8%)
