7. 1
What I Need to Know
Maintaining a clean work environment is important in preventing foodborne
illness. Foodborne illness or food poisoning is caused by consuming food
contaminated with pathogenic bacteria, toxins, viruses, and parasites. These
harmful microorganisms will continue to grow on dirty areas and then contaminate
food. Not all surfaces that looks clean is sanitary, so we must always be sure that
we clean and sanitize a work area before starting to prepare our food. It is not
enough to just use soap and other detergents. It is also important to apply
sanitation. If we will do both cleaning and sanitizing, then we can now assure that
the area is safe for food preparation.
After reading this module, the learners should be able to:
1. Select various types of chemicals for cleaning and sanitizing kitchen tools,
equipment, and paraphernalia.
2. Clean and sanitize kitchen tools and equipment following manufacturer’s
instructions.
3. Use cleaning tools, equipment, and paraphernalia in accordance to
standard operating procedures.
Read and understand the content of every topic because you will be
assessed on what have you learned or understood by answering or performing the
activities provided.

What’s New
COVID19 is a very serious matter nowadays. This pandemic urges
everyone to observe proper sanitation to stop the spread of the virus. Proper hand
washing therefore is one of the ways to keep oneself clean and keeps us from
being infected. If we do not wash our hands, we may transfer the virus by touching
the kitchen tools and equipment when we cook. Thus, it is also very necessary to
clean and sanitize our kitchen tools and equipment and other paraphernalia to
keep us safe.

What is It
Guide Questions:
1. What is for you the difference between cleaning and sanitizing?
2. If asked to clean and sanitize kitchen tools, equipment and paraphernalia,
what are the things you need to use?
CLEANING AND SANITIZING
Cleaning and sanitizing may be the most important aspect of a sanitation
program. Improperly cleaned and sanitized areas allow harmful microorganisms
to be transferred from one food to another food.
Cleaning is the process of removing unwanted smell, dust, dirt, or stains from
surfaces. Cleaning is done with a cleaning agent that removes food, soil, or other
substances on a food-contact surface. A food-contact surface is the surface of
equipment or utensil that food normally comes into contact. When using cleaning
agents, the label must be checked if the product can be used and does not leave
an unsafe residue on the food-contact surface.
Cleaning agents are divided into four categories:
1. Detergents are used to wash tableware,
surfaces, and equipment. Detergents can
penetrate soil quickly and soften it. Examples
include liquid and paste dishwashing detergents.

12. 6
2. Solvent cleaners are used on surfaces where
grease has burned on. Solvent cleaners are often
called degreasers. Ovens, grills and range top
are examples of areas that need frequent
degreasing.
3. Acid cleaners are used in removing mineral
deposits and other soils that detergents cannot
remove. These cleaners are often used to
remove dirt and stain in ware washing machines
and steam tables.
4. Abrasive cleaners are used to remove heavy
collected soil that is difficult to remove with
detergents. Some abrasive cleaners also
disinfect.
Sanitizing is the process of removing harmful bacteria using heat and
water, or chemicals, or a combination of both. The term sanitary refers to the state
of a food contact surface or utensil where it does not contain microorganisms at a
level that would permit the transmission of infectious disease or compromise food
safety. Sanitizers are substances capable of destroying microorganisms including
those bacteria that cause food poisoning and other diseases.
Sanitizing Methods
1. Heat. There are three methods of using heat to sanitize surfaces – steam,
hot water, and hot air. Hot water is the most common method used in
restaurants. If hot water is used in the third compartment of a three-
compartment sink, it must be at least 171°F (77°C). If a high-temperature
ware washing machine is used to sanitize cleaned dishes, the final

13. 7
sanitizing rinse must be at least 180°F (82°C). For stationary rack, single
temperature machines, it must be at least 165°F (74°C). Cleaned items
must be exposed to these temperatures for at least 30 seconds.
2. Chemicals. Chemicals that are approved sanitizers are chlorine, iodine,
and quaternary ammonium. Different factors influence the effectiveness of
chemical sanitizers. The three factors that must be considered are:
 Concentration - The presence of too little sanitizer is not enough to reduce
harmful microorganisms. Too much can be dangerous.
 Temperature - Generally chemical sanitizers work best in water that is
between 55°F (13°C) and 120°F (49°C).
 Contact time - In order for the sanitizer to kill harmful microorganisms, the
cleaned item must be in contact with the sanitizer (either heat or approved
chemical) for the recommended length of time.
Approved chemical sanitizers:
Chlorine Iodine Quaternary Ammonium

RINSE
WASH
AIR DRY
SANITIZE

18. 12
3. Work from lightly to heavily soiled
dishes. Start by cleaning drinking glasses then
move onto cleaning your plates and bowls.
Lastly, soak and clean any pots, pans, or other
cookware.
4. Wash your dishes underwater with a
sponge or dishcloth. Keep the dishes
underwater as you scrub them to loosen any
stuck-on food.
5. Rinse off the soap with clean hot
water. After you wash a dish, rinse it underneath
the hottest water you can handle until the suds
are gone.
6. Let the dishes dry in a rack or on a clean
towel. Set the dishes inside of a drying rack on
your counter. If you don’t have a drying rack, set
the dishes upside-down on a clean towel so they
have a chance to dry.
C. Cleaning Dishes and Kitchen Tools Using Dishwasher Machine
1. Remove leftover food on your plates. Try
to remove as much as you can so it doesn’t
clog your dishwasher. After you scrape the
food from the dishes, rinse them in the sink to
remove any smaller pieces that still may be
stucked.

19. 13
2. Put cups, plastics, and bowls on the top
shelf of your dishwasher. Make sure all of your
dishes are dishwasher-safe, or else they may
melt or get destroyed when you run a cleaning
cycle.
3. Load plates and cookware on the bottom
rack. Keep large flat pans on the sides or the
back of the bottom rack so it doesn’t block the
detergent compartment. Stand your plates on
end so the dirty side faces the water sprayer.
4. Put the silverware into the compartment
on the bottom rack or door. Make sure the
handles of your silverware are at the bottom of
the compartment so the dirty parts get cleaned.
Leave space in between each utensil so the
water can get in between the surfaces.
5. Fill the designated compartment with a
detergent made for use in a dishwasher. Avoid
using liquid dish soap since it will leave foamy
residue on your dishes.
6. Turn on the dishwasher. Close the
dishwasher door, select the cycle you want to
run, and press start. Let the dishwasher run until
it’s completed.
Note:
 Set your dishwasher in normal cycle if you are doing a regular wash.
 Set your dishwasher in delicate cycle if your dishes are lightly soiled or if
you have glassware in your dishwasher.

20. 14
 Set your dishwasher in heavy duty cycle if you’re cleaning pots and
pans.
