Ice Machine Descaling & Sanitation Protocol

Protocol Series Last Updated: March 2026 B2B Verified

Commercial ice machines are the most frequently neglected piece of equipment in a kitchen. This guide covers why rigorous descaling and sanitation is legally and mechanically required.

The Menace of Scale

Hard water scale builds up on the evaporator plates. When this happens, ice sticks to the plates instead of dropping during the harvest cycle. The machine will continually run its freeze cycle, eventually creating a solid block of ice that crushes the internal evaporator fins, destroying the machine.

HP Mechanical Protocol

Our preventative maintenance includes fully dismantling the water trough and distribution tubes, running commercial-grade nickel-safe descaler through the pump, and sanitizing the bin to prevent pink slime (Serratia marcescens) growth, ensuring full health code compliance and uninterrupted ice production.
