What is the only effective cleaning solution for spills of blood or other bodily fluids?

The only effective cleaning solution for spills of blood or other bodily fluids is a mixture of 1 part bleach to 10 parts water. This solution is appropriate because bleach is a strong disinfectant that can effectively kill a wide range of pathogens, including bacteria, viruses, and fungi that may be present in bodily fluids. When dealing with biohazardous substances such as blood, using a proper disinfecting solution is crucial for ensuring safety and preventing the spread of infectious diseases.

This concentration is widely recommended by health organizations, as it strikes a balance between efficacy and safety for surfaces and personnel involved in the cleaning process. The other options, while they may have some cleaning properties, do not provide the same level of disinfection required for handling potentially infectious materials.
