When it comes to kitchen hygiene, your cutting board might be harbouring more germs than you think—potentially even surpassing the grimy reputation of a toilet seat. In light of this startling revelation, we consulted Dr. Keith R. Schneider, a food safety professor from the University of Florida, to unravel the best practices for cleaning this essential kitchen tool. With his expert insights, we aim to empower you to maintain a safe and sanitary cooking environment.
The Germs Lurking on Your Cutting Board
It’s easy to overlook the cleanliness of your cutting board, especially when it’s tucked away between uses. However, microbiologists have identified cutting boards, along with kitchen sponges and water bottles, as some of the most germ-infested items in our homes. While it’s wise not to spiral into a state of germaphobic frenzy, it’s crucial to pay special attention to these surfaces after you’ve sliced and diced various ingredients—particularly raw meats which can harbour dangerous bacteria like salmonella and E. coli.
Dr. Schneider reassures us that cleaning with good old soap and water remains a reliable method for most situations. However, understanding the nuances of cutting board maintenance can significantly reduce your risk of an unpleasant surprise during meal prep.
Effective Cleaning Techniques
Choosing the Right Tools
Most plastic, glass, composite, or stainless-steel cutting boards are dishwasher safe. Simply place them on the bottom rack, where high temperatures will not only wash away food particles but also sanitise the surface. However, wooden boards require a different approach; they must be hand-washed to prevent warping and cracking.

For a gentle clean, consider compostable sponges, such as those from Blueland, which have garnered praise from food writers and chefs alike. After washing, ensure your wooden board is treated with food-grade oil to prolong its life—applying this oil after washing can protect against stains and warping.
Preventing Bacterial Growth
Once you’ve finished washing your cutting board, it’s essential to dry it properly. Use a cloth or paper towels to absorb any remaining moisture, as dampness can create a breeding ground for bacteria. Store your board vertically against a wall or another object to allow for adequate airflow, ensuring it dries completely before being put away.
Do You Need Antibacterial Soap?
Fortunately, standard dish soap, such as Dawn or Palmolive, is usually sufficient for cleaning your cutting board. Dr. Schneider notes that antibacterial soaps offer little added benefit over regular soaps, meaning a good scrub is often all it takes to keep your board clean.
The Right Way to Sanitize
While soap and water may suffice for general cleaning, certain situations warrant more rigorous sanitisation—especially after cutting raw meat. In these cases, a bleach solution is recommended. Dilute one tablespoon of unscented household bleach
