sanitizing steps, the agent applied in the sanitizing step shall be the

same detergent-sanitizer that is used in the washing step.

4-4.3 Warewashing Equipment, Determining Chemical Sanitizer

Concentration

Concentration of the sanitizing solution shall be accurately determined by

using a test kit or other device.

4-4.4 Hot Water and Chemical Sanitizing

After washing, equipment food-contact surfaces and utensils shall be

sanitized in:

a. Hot water manual operations by immersion for at least 30 seconds as
