Step 7 Mix a solution of cleaner and warm water.
Depending on 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.
Solution Type Water Mixed with
Cleaner 1 gal (4 L)
16 oz (500 ml)
cleaner
Step 8 Use 1/2 of the cleaner/water solution 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 brush, sponge or cloth (not a wire brush) to
carefully clean the parts. Soak the 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. Use a nylon brush or cloth to
thoroughly clean the following ice machine areas:
• Evaporator plastic parts – including top, bottom and sides
• Bin bottom, sides and top
Rinse all areas thoroughly with clean water.
Step 10 Mix a solution of sanitizer and warm water.
Solution Type Water Mixed With
Sanitizer 6 gal (23 L)
4 oz (120 ml)
sanitizer
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 bin. Use a cloth
or sponge to liberally apply the solution. When sanitizing,
pay particular attention to the following areas:
• Evaporator plastic parts – including top, bottom and sides
• Bin bottom, sides and top
Do not rinse the sanitized areas.
Step 13 Replace all removed components.
Step 14 Reapply power and water to the ice machine and
place the toggle switch in the WASH position.
Step 15 Add the proper amount of Manitowoc Ice Machine
Sanitizer to the water trough.
Model Amount of Sanitizer

Step 16 Wait until the sanitize cycle is complete
(approximately 45 minutes) then place the toggle switch in
the OFF position, disconnect power and water supplies to the
ice machine.
