What is the minimum proportion of bleach recommended for disinfecting surfaces?

For disinfecting surfaces, the recommended minimum proportion of bleach is critical to ensure effective sanitation while also being safe for users. The correct choice involves using 1 tablespoon of bleach to 1 quart of water. This dilution allows for effective disinfection, as bleach in lower concentrations still retains its ability to kill germs and pathogens while minimizing potential damage to surfaces and reducing the risk of harmful fumes.

Using too strong a solution can lead to damage to certain surfaces or materials, while using too weak a solution may not effectively eliminate bacteria and viruses. This balance is essential in both residential and institutional settings where hygiene is paramount.
