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
