E. CLEANING AND SANITIZING INFORMATION
Special consideration is required when it comes to food
safety and proper cleaning and sanitizing.

SOIL MATERIALS ASSOCIATED WITH FROZEN
DESSERT MACHINES
MILKFAT/BUTTERFAT – As components of ice-cream/
frozen custard mix, these soils will accumulate on the
interior surfaces of the machine and its parts. Fats are
difficulttoremoveand helpattributetomilkstone buildup.
MILKSTONE – Is a white/gray film that forms on equip-
mentandutensilsthatcomeincontactwithdairyproducts.
Thesefilmswillaccumulateslowlyonsurfacesbecauseof
ineffectivecleaning,useof hard water,orboth. Milkstone
is usually a porous deposit, which will harbor microbial
contaminants and eventually defy sanitizing efforts.
Once milkstone has formed, it is very difficult to remove.
Without using the correct product and procedure, it is
nearly impossible to remove a thick layer of milkstone.
(NOTE: general-purpose cleaners DO NOT remove
milkstone.) This can lead to high bacteria counts and a
food safety dilemma.

IMPORTANT DIFFERENCES BETWEEN CLEANING
ANDSANITIZING
CLEANING vs. SANITIZING
Itisimportanttodistinguishbetweencleaningandsanitiz-
ing. Although these terms may sound synonymous, they
are not. BOTH are required for adequate food safety and
proper machine maintenance.
CLEANING
• Is the removal of soil materials from a surface.
• Is a prerequisite for effective sanitizing.
NOTE
An UNCLEAN surface will harbor bacteria that can
defy sanitizing efforts.
Bacteria can develop and resist sanitizing efforts within a
layer of soil material (milkstone). Thorough cleaning pro-
cedures that involve milkstone removal are critical for
operators of frozen dessert machines.
SANITIZING
• Kills bacteria.
• Can be effective on clean surfaces only.
NOTE
Using a SANITIZER on an unclean surface will not

PROPERDAILY MAINTENANCE: THE ONLY WAY TO
ASSUREFOODSAFETYANDPRODUCTQUALITY
Proper daily maintenance can involve a wide variety of
products and procedures. Overall, the products and pro-
cedures fall into three separate categories. (Please note
that this is a brief overview intended for informational
purposesonly.)
1. CLEANING–Thisinvolvesdrainingmixfromthe
machinebarrelandrinsingthemachinewithwater.
Next,acleanerisrunthroughthemachine.Then,
the machine is disassembled and removable
parts are taken to the sink for cleaning.
2. MILKSTONE REMOVAL – Since almost all
cleaners do not have the ability to remove
milkstone, the use of a delimer becomes

12
necessary. Although this procedure may not be
needed on a daily basis, it will usually follow the
cleaning procedure. It requires letting a delimer
solution soak in the machine for an extended
period. Individual parts are also soaked in a
deliming solution for an extended period (more
about delimers in Additional Information).
3. SANITIZING–Afterthemachinehasbeencleaned
and contains no milkstone, the machine is
reassembled. Then a FDA-approved sanitizing
solutionisrunthroughthemachinetokillbacteria.
The machine is then ready for food preparation.
As a recommended cleaner and sanitizer for your frozen
dessertmachine,STERA-SHEENhasproventobeoneof
the best daily maintenance products for:
• CLEANING – Thorough removal of all solids
including butterfat and milk fat.
• MILKSTONE REMOVAL – Complete removal of
milkstone.
• SANITIZING – FDA-approved no rinse sanitizer
for food contact surfaces.
ADDITIONALINFORMATION
THE USE OF DELIMERS
A delimer is a strong acid that has the ability to dissolve
milkstone. This type of chemical may become necessary
once high levels of milkstone have developed. While
these products are very effective for removing HIGH
levels of milkstone, they are not ideal for two reasons:
1. PRODUCTSAFETY–Strongacidsaredangerous
chemicals and handling them requires safety
2. MACHINE DAMAGE – Strong acids will attack
metal and rubber causing premature wear of
parts. The use of a delimer needs to be closely
monitored to avoid damage to machine surfaces
and parts.
WithproperdailyuseofSTERA-SHEENoritsequivalent,
there is no need for the use of a DELIMER.
DO NOT USE BLEACH
• BLEACH HAS ABSOLUTELY NO CLEANING
PROPERTIES.
• BLEACHISCORROSIVE.Itcanandwilldamage
componentsofthemachinecausingprematurewearand
metal corrosion.
GENERAL PURPOSE CLEANERS
General purpose cleaners do not have the ability to re-
move milkstone. Milkstone will become a problem if not
remediedwithadditionalproductsandprocedures.
THEUSEOFCHLORINETESTSTRIPS
“Test strips” are used to determine concentrations of
active chlorine in sanitizing solutions. To use the strips,
tearoff a smallportion andsubmerge it intothe sanitizing
solution.Then,comparethecolorchangetothecolorkey
on the side of the test strip dispenser to determine the
approximate chlorine concentration.
The ideal concentration of chlorine needs to be 100 ppm
(as stated by the FDA). NOTE
Followthedirectionsonthecontainerforpropercon-
centration.
There are two main factors that contribute to falling chlo-
rine concentrations in a sanitizing solution.
1. PRODUCT USE – As the chlorine in the solution
is being used, chlorine concentrations fall.
2. TIME–Astimepasses,smallamountsofchlorine
“evaporate” from the solution. (That is why you
can smell it.)
Sanitizingsolutionsshouldnotbeallowedtofallbelow100
ppm chlorine. New solutions should be mixed once old
solutions become ineffective.

4.2 TROUBLESHOOTING ERROR CODES
Error Code 1 - Soft Error
The Soft Error (E1) is an internal control board
error that is logged for future analysis. The
refrigerationisneverstoppedandthemachinewill
continue to operate normally.
Error Code 2 - High Torque
If the control panel displays a High Torque Error
(E2), the controller has sensed that the drive
motor is running at 125% of the service factor
amps (SFA) for 10 or more seconds. Place the
Main Power Off/On switch in the OFF position,
wait until the product in the barrel thaws to a
