Step 7 Mix a solution of cleaner and warm water.
Depending upon the amount of mineral buildup, a
larger quantity of solution may be required. Use the
ratio in the table below to mix enough solution to
thoroughly clean all parts.
Step 8 Use 1/2 of the cleaner/water mixture to clean
all components. The cleaner solution will foam when it
contacts lime scale and mineral deposits; once the
foaming stops use a soft-bristle nylon brush, sponge
or cloth (NOT a wire brush) to carefully clean the parts.
Soak parts for 5 minutes (15 - 20 minutes for heavily
scaled parts). Rinse all components with clean water.
Step 9 While components are soaking, use 1/2 of the
cleaner/water solution to clean all foodzone surfaces
of the ice machine and bin (or dispenser). Use a nylon
brush or cloth to thoroughly clean the following ice
machine areas:
• Side walls
• Base (area above water trough)
• Evaporator plastic parts - including top, bottom,
and sides
• Bin or dispenser
Rinse all areas thoroughly with clean water.
Step 10 Mix a solution of sanitizer and warm water.
Step 11 Use 1/2 of the sanitizer/water solution to
sanitize all removed components. Use a cloth or
sponge to liberally apply the solution to all surfaces of
the removed parts or soak the removed parts in the
sanitizer/water solution. Do not rinse parts after
sanitizing.
Step 12 Use 1/2 of the sanitizer/water solution to
sanitize all foodzone surfaces of the ice machine and
