Overview
This chapter explains how to keep surfaces, dishes, and the whole building clean and safe. You will learn the difference between cleaning and sanitizing, when to do both, how to use a three-compartment sink, how to handle chemicals, and how to keep garbage and pests under control.
Cleaning removes food and dirt from a surface. Sanitizing reduces germs on a clean surface to safe levels. The order is clean, rinse, sanitize, and air-dry. Clean and sanitize a food-contact surface after you use it, before you work with a different type of food, after an interruption that may have contaminated it, and at least every 4 hours if it is in constant use.
At a three-compartment sink, scrape food off first. Then wash in detergent, rinse in clean water, sanitize, and let items air-dry. Never towel-dry sanitized items. Change the sanitizer when it is dirty or weak, and check it with a test kit. Keep wet wiping cloths in sanitizer solution between uses, and store clean dishes dry, off the floor, and upside down.
Store chemicals in a separate area, away from and never above food. Label any working container with the chemical's common name, never mix chemicals, and use the Safety Data Sheet (SDS) to learn about dangers and first aid. Remove garbage from prep areas often and keep containers covered. If you see signs of pests, such as droppings, gnaw marks, nests, or a strong oily smell, tell your manager. Only a licensed pest control operator should apply pesticides.
Key concepts
Cleaning vs. sanitizing
Cleaning removes food and dirt. Sanitizing reduces germs on a clean surface to safe levels. Sanitizer does not work well on a dirty surface.
Memory tipClean first, then sanitize.
When to clean and sanitize
After using a surface, before working with a different type of food, after an interruption, and at least every 4 hours for items in constant use.
Memory tipConstant use: every 4 hours.

Three-compartment sink
Scrape, then wash in detergent, rinse in clean water, sanitize, and air-dry. Change the sanitizer when it is dirty and check it with a test kit.
Memory tipScrape, wash, rinse, sanitize, air-dry.
Chemical storage and labels
Keep chemicals in a separate area away from food and prep areas, and never above food. Label working containers with the chemical's common name. Never mix chemicals.
Memory tipChemicals go away from and below food.
Safety Data Sheet (SDS)
A sheet from the chemical's maker that explains its dangers, safe use and storage, and first aid if someone is exposed.
Memory tipSDS = safety and first aid for a chemical.
Signs of pests
Droppings, gnaw marks, nests, egg cases, a strong oily smell, and live or dead pests. Report them to your manager. A licensed pest control operator should apply pesticides.
Memory tipSee it, report it; do not spray it yourself.
Often tested
- Never towel-dry sanitized dishes or surfaces; let them air-dry.
- Do not stack dishes while they are still wet.
- Keep wet wiping cloths in sanitizer solution between uses.
- Dump mop water only in a service (mop) sink.
- Remove garbage from prep areas often and keep containers covered.
- Store clean dishes and utensils at least 6 inches off the floor.

Verified practice questions from this unit.
Question 1. What is the difference between cleaning and sanitizing?
- ① Cleaning removes food and dirt; sanitizing reduces germs to safe levels
- ② Cleaning kills all germs; sanitizing removes dirt
- ③ They mean the same thing
- ④ Sanitizing is only needed for floors and walls
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ① Cleaning removes food and dirt; sanitizing reduces germs to safe levels
Key point: Cleaning removes dirt; sanitizing cuts germs to safe levels
Cleaning removes food and dirt from a surface. Sanitizing reduces germs on a clean surface to safe levels. You must clean first, because sanitizer does not work well on a dirty surface.
Wrong choices
- Cleaning kills all germs; sanitizing removes dirt: This has the two jobs backward.
- They mean the same thing: They are two different steps, and both are needed for food-contact surfaces.
- Sanitizing is only needed for floors and walls: Sanitizing is most important for surfaces that touch food, like cutting boards and utensils.
Question 2. What is the correct order for cleaning and sanitizing a prep table?
- ① Sanitize, rinse, clean, air-dry
- ② Clean, rinse, sanitize, air-dry
- ③ Rinse, sanitize, clean, towel-dry
- ④ Clean, sanitize, rinse, towel-dry
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ② Clean, rinse, sanitize, air-dry
Key point: Clean, rinse, sanitize, air-dry
The order is clean, rinse, sanitize, air-dry. Scrape and clean off food, rinse away soap and dirt, apply sanitizer, and then let the surface air-dry. Do not rinse off the sanitizer.
Wrong choices
- Sanitize, rinse, clean, air-dry: Sanitizer does not work on a dirty surface, so cleaning must come first.
- Rinse, sanitize, clean, towel-dry: Cleaning must come first, and you should not towel-dry.
- Clean, sanitize, rinse, towel-dry: You should not rinse off sanitizer or towel-dry. Both can put germs back on the surface.
Question 3. A cutting board is in constant use all day to slice deli meat. How often must it be cleaned and sanitized?
- ① Once at the end of the shift
- ② Every 8 hours
- ③ Once a week
- ④ At least every 4 hours
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ④ At least every 4 hours
Key point: Constant use: clean and sanitize every 4 hours
Food-contact surfaces that are in constant use must be cleaned and sanitized at least every 4 hours. Germs build up on the surface over time, even when you work with only one food.
Wrong choices
- Once at the end of the shift: The end of the shift may be more than 4 hours away.
- Every 8 hours: 8 hours is twice as long as the limit.
- Once a week: Once a week is far too long for a surface that touches food.
