How should sanitizer chemicals be used?

  1. According to personal judgment

  2. In very hot water

  3. Mixed with detergents

  4. According to the sanitizer label instructions

The correct answer is: According to the sanitizer label instructions

Sanitizer chemicals should be used according to the instructions provided on the label to ensure proper usage and effectiveness. Relying on personal judgment may result in inadequate sanitation. Using very hot water may also not be effective as it can deactivate certain chemicals and may lead to unnecessary wastage of resources. Similarly, mixing with detergents may also reduce the effectiveness of the sanitizer. Therefore, it is important to follow the specific instructions provided by the manufacturer on the label for optimal and safe use of sanitizer chemicals.
