When should sanitizer buckets be changed?

Sanitizer buckets should be changed every 4 hours or when soiled to ensure the effectiveness of the sanitizing solution. Over time, the efficacy of the sanitizer diminishes due to dilution, contamination, and the buildup of debris, which can compromise food safety. Regularly changing the solution ensures that surfaces are consistently sanitized and helps prevent the growth of harmful bacteria in a fast-paced food service environment like Burger King.

Choosing to change the sanitizer every hour may lead to unnecessary waste and is not typically required unless the environment is particularly high-risk. Changing it every shift may not provide adequate oversight for food safety, as the solution could become ineffective during peak operation hours. Changing it daily does not meet the health and safety standards needed throughout the day in a busy kitchen setting, where contamination can occur frequently. Thus, the practice of changing sanitizer buckets every 4 hours or when they become soiled provides a balance between efficiency and safety.
