Guide to Warewashing & Janitorial Equipment
In both cases, the sanitized ware
must be air-dried — never
towel-dried — to prevent
recontamination. And, operators
should routinely test rinse
temperatures using thermal
labels or dishwasher-safe
thermometers to ensure
compliance. Staff training is
essential. If the spray arms
aren’t spinning, if detergent
levels are low, or if the sanitizer
isn’t dispensing, the result is
ineffective sanitation — even if
the wares look clean.
