1 Chapter 11 Cleaning and Sanitizing

2 How and When to Clean and Sanitize Cleaning Process of removing food and other dirt from a surface All surfaces must be cleaned and rinsed Sanitizing Process of reducing pathogens on a surface to safe levels Surfaces that touch food must be cleaned and sanitized 11-2

3 How and When to Clean and Sanitize Steps for cleaning and sanitizing: 1. Clean the surface 2. Rinse the surface 3. Sanitize the surface 4. Allow the surface to air-dry 11-3

4 Food-contact surfaces must be cleaned and sanitized: After they are used Before working with a different type of food Any time a task was interrupted and the items may have been contaminated At 4-hour intervals if the items are in constant use How and When to Clean and Sanitize 11-4

5 Cleaners Cleaners must be: Stable and noncorrosive Safe to use When using them: Follow manufacturers’ instructions Never combine cleaners 11-5

6 Types of Detergents General-purpose detergents Remove dirt from floors, walls, ceilings, prep surfaces and most equipment surfaces Heavy-duty detergents Remove wax, aged or dried dirt, wax, and baked-on grease Cleaners 11-6

7 Degreasers Have ingredients for dissolving grease Work well on burned-on grease Backsplashes, oven doors, and range hoods Cleaners 11-7

8 Delimers Acid cleaners used on mineral deposits and dirt that other cleaners can’t remove Steam tables Dishwashers Cleaners 11-8

9 Abrasive Cleaners Have a scouring agent that helps scrub hard-to-remove dirt Used to remove baked-on food Can scratch surfaces Cleaners 11-9

10 Surfaces can be sanitized using: Heat The water must be at least 171F°(77°C) Immerse the item for 30 seconds Chemicals Chlorine Iodine Quats Sanitizing 11-10

11 Chemical Sanitizing Food-contact surfaces can be sanitized by either: Soaking them in a sanitizing solution Rinsing, swabbing, or spraying them with a sanitizing solution In some cases a detergent- sanitizer can be used: 1. Use it once to clean 2. Use it a second time to sanitize 11-11

12 Concentration Sanitizers should be mixed with water to the right concentration Not enough sanitizer: May make the solution weak and useless Too much sanitizer: May make the solution too strong, unsafe, and corrode metal Sanitizer Effectiveness 11-12

13 Concentration continued Check concentration with a test kit Change the solution when: It’s dirty The concentration is too low Sanitizer Effectiveness 11-13

14 Temperature Follow manufacturer’s recommendations for the right temperature Contact Time The sanitizer must make contact with the object for a specific amount of time Minimum times differ for each sanitizer Sanitizer Effectiveness 11-14

15 Dishwashing High-Temperature Machines Final sanitizing rinse must be at least 180°F (82°C) 165°F (74°C) for stationary rack, single-temperature machines Chemical-Sanitizing Machines Follow the temperature guidelines provided by the manufacturer 11-16

16 Guidelines Clean the machine as often as needed Scrape, rinse, or soak items before washing Use the right rack for the items being washed Check racks as they come out of the machine Air-dry all items Check the machine’s water temperature and pressure Dishwasher Operation 11-17

17 Manual Dishwashing Steps for Cleaning and Sanitizing 11-18

18 Apply Your Knowledge: What’s Wrong with This Picture? How many problems can you spot?

19 Storing Tableware and Equipment When storing clean and sanitized tableware and equipment: Store them at least 6” (15 cm) off the floor Clean and sanitize drawers and shelves before items are stored Store glasses and cups upside down on a clean and sanitized shelf or rack Store utensils with handles up Cover the food-contact surfaces of stationary equipment until ready for use 11-19

20 When cleaning the premises: Clean nonfood-contact surfaces regularly Includes floors, ceilings, walls, equipment exteriors, etc. Prevents dust, dirt, food residue and other debris from building up. Cleaning and Sanitizing in the Operation 11-21

21 Prevent cleaning tools from contaminating surfaces: Clean tools before storing them Assign tools for specific tasks Replace worn tools Never use towels meant for cleaning food spills for any other purpose Store towels in a sanitizer solution between uses Cleaning and Sanitizing in the Operation 11-22

22 Cleaning and Sanitizing in the Operation Storing Cleaning Tools and Chemicals Place in a separate area away from food and food-prep areas The storage area should have: Utility sink for filling buckets and washing cleaning tools Floor drain for dumping dirty water Hooks for hanging cleaning tools 11-23

23 Using Foodservice Chemicals Chemicals Only purchase those approved for use in foodservice operations Store them in their original containers away from food and food-prep areas If transferring them to a new container, label it with the common name of the chemical 11-24

24 Chemicals continued Keep MSDS for each chemical When throwing them away, follow: Instructions on the label Local regulatory requirements Using Foodservice Chemicals 11-25

25 Developing a Cleaning Program To develop an effective cleaning program: Create a master cleaning schedule Train your employees to follow it Monitor the program to make sure it works 11-26

26 Developing a Cleaning Program To create a master cleaning schedule, identify: What should be cleaned Who should clean it When it should be cleaned How it should be cleaned 11-27

27 Developing a Cleaning Program When monitoring the master cleaning program: Supervise daily cleaning routines Check cleaning tasks against the master schedule every day Change the master schedule as needed Ask staff for input on the program 11-29
