What dilution of bleach solution is used for body fluid spill cleanup on a pool surface?

Disinfection after a body fluid spill on a pool surface requires a dilution strong enough to inactivate pathogens but still safe for the surface and users. A 1:10 dilution—one part household bleach to nine parts water—produces about 0.5% sodium hypochlorite, which is commonly recommended for cleaning spills on nonporous pool surfaces. This concentration is effective for disinfecting, while more concentrated dilutions (like 2:1 or 1:1) are unnecessarily harsh and can damage surfaces or cause stronger fumes, and a 1:100 dilution would be too weak to reliably disinfect. After applying, ensure the surface remains wet for the required contact time to achieve disinfection.
