Reason 1
They Clean Hidden Parts Detergent Never Reaches
Regular dishwasher detergent is designed to remove food and grease from plates, glasses, pans, and utensils.
It is not designed to deep-clean the filter, drain, seals, spray arms, heating area, pump, or internal water paths.
Those hidden areas can collect months of grease, food residue, detergent film, and grime while the visible tub still looks clean.
During a hot cycle, dishwasher cleaner circulates through the same internal system that regular detergent leaves behind.
The machine can look spotless on the outside while hidden buildup continues growing inside.
