For manual hot-water sanitizing in a three-compartment sink, items must be immersed in water maintained at 171°F or hotter for at least 30 seconds; heat alone does the sanitizing, so the water has to be hot enough to kill pathogens in that half minute. 110°F is only the minimum for the detergent wash compartment, 135°F is a hot-holding temperature, and 75°F sits inside the danger zone. None of the three sanitizes, no matter how long the soak runs.
