How do you deactivate Bleach?

To deactivate bleach, you can neutralize it using a solution of sodium thiOSulfate or a mixture of vinegar and baking soda. Sodium thiOSulfate is commonly used in pools and can effectively neutralize chlorine. If using vinegar and baking soda, mix them in a well-ventilated area and apply the mixture to the bleach. Always take precautions, such as wearing gloves and ensuring proper ventilation, when handling chemicals.
