What is the mixture for low-level disinfection using household bleach?

The correct mixture for low-level disinfection using household bleach is two teaspoons of bleach to one gallon of water. This dilution is effective for disinfecting surfaces while being safe for general use in many household applications. It provides an appropriate concentration of sodium hypochlorite, which is the active ingredient in bleach that kills bacteria and viruses.

In practical terms, this mixture is designed to be strong enough to disinfect while minimizing the potential for damage to surfaces or overexposure to strong chemicals, which can occur if the concentration is too high. By using the recommended ratio, users can achieve germicidal efficacy without unnecessarily increasing risks associated with higher concentrations of bleach, such as fumes or surface damage.
