How often should chlorine bleach be changed as a disinfectant?

Chlorine bleach loses its effectiveness over time due to evaporation and degradation, which makes it necessary to change it frequently to ensure it maintains its disinfecting capabilities. The correct frequency for changing chlorine bleach as a disinfectant is daily. This is crucial in maintaining a safe and sanitary environment, especially in settings like salons or spas where hygiene is paramount.

By changing the solution daily, you ensure that the oxidizing power of the bleach is sufficient to effectively eliminate bacteria, viruses, and fungi. Regularly replacing the bleach helps to prevent the use of weakened solutions that may not meet health and safety standards. While other options suggest longer intervals, these do not account for the rapid loss of efficacy that occurs with chlorine bleach, which is why daily replacement is essential for effective disinfection.
