Cutting boards are indispensable kitchen tools; however, they can also harbor harmful bacteria if not cleaned. Understanding how to sanitize cutting boards is crucial for maintaining a healthy kitchen environment. In this guide, we’ll walk you through practical techniques for cleaning and disinfecting wooden and plastic cutting boards, ensuring they are safe for food preparation.
Why Proper Cleaning Matters

Uncleaned cutting boards can be a harboring ground for bacterial growth.
Cutting boards, whether wooden or plastic, are directly exposed to various types of food, making them prime spots for cross-contamination and bacterial growth. By learning how to sanitize cutting boards correctly, you can prevent foodborne illnesses and keep your meals safe.
How to Clean Wooden Cutting Boards

Wooden cutting boards are well-known for their durability and aesthetic appeal. However, they require specific care to maintain their quality and hygiene.
- Daily Cleaning Routine: Wash your wooden cutting board with hot water and dish soap after each use. Use a sponge to scrub the surface gently. Do not soak the board in water, which can cause the wood to warp and crack.
- Deep Cleaning and Deodorizing: To deep clean and deodorize your wooden cutting board, sprinkle coarse salt or baking soda over the surface. Cut a lemon in half and use it to scrub the board, applying pressure to release the lemon juice. This natural method helps to eliminate odors and bacteria. Rinse the board with hot water and dry it off with a towel.
- Sanitizing Wooden Cutting Boards: It is essential to know how to sanitize wood cutting boards. Mix one tablespoon of white vinegar with one cup of water. Dampen a cloth with the solution and wipe down the board. Vinegar is a natural disinfectant that will help kill bacteria without damaging the wood.
- Regular Maintenance: Apply food-grade mineral oil to your wooden cutting board once a month. This keeps the wood hydrated and prevents cracking. Spread a thin layer of oil on the surface and let it absorb for several hours or overnight. Wipe off any excess oil with a clean cloth.
How to Clean Plastic Cutting Boards
Plastic cutting boards don’t look as great but are much easier to clean and sanitize than wooden ones. Here’s how to keep them in top condition:
- Daily Cleaning Routine: Wash your plastic cutting board with hot, soapy water after each use. Use a sponge or brush to scrub away food particles. Rinse off thoroughly and dry with a towel, or let it air dry.
- Deep Cleaning: Place your plastic cutting board in the dishwasher for a deeper clean. The high temperature will help kill any remaining bacteria. However, if your board is heavily stained, create a paste using baking soda and water. Scrub the board with the paste and a brush, then rinse thoroughly.
- Sanitizing Plastic Cutting Boards: Knowing how to sanitize cutting boards made of plastic is straightforward. Prepare a sanitizing solution with one tablespoon of bleach per gallon of water. Soak the cutting board in the solution for a few minutes, then rinse with hot water and dry thoroughly. This method ensures your board is free of harmful bacteria.
- Preventing Stains and Odors: Rub your plastic cutting board with lemon juice or white vinegar to prevent stains and odors. Both are natural deodorizers and disinfectants that help keep your board fresh.
