Are you struggling with the lingering smell of onions on your wood cutting board? In this guide, we’ll explore effective methods for how to remove onion smell from wood cutting board, leaving it clean and odour-free.

Why does onion smell linger on wood cutting boards
Wood is a porous material, which means it has tiny openings that can trap and absorb odors. When you cut onions on a wood cutting board, the compounds responsible for the strong smell can seep into the wood’s fibers. Unlike plastic or glass cutting boards, wood has a natural ability to hold onto these odors, making it more challenging to remove them through regular washing.
Additionally, the enzymes present in onions can further contribute to the lingering smell on wood cutting boards. These enzymes can penetrate the wood and continue to release their aroma long after the onions have been removed.

Wooden cutting boards are commonly used in kitchens, but some may wonder if it’s safe to cut onions on them. Yes, it’s perfectly fine to cut onions on a wooden cutting board. However, onions can leave behind a strong odour that may be difficult to remove if not cleaned properly.

Proper cleaning and maintenance to prevent odors on wood cutting boards
Prevention is key when it comes to avoiding lingering onion smells on wood cutting boards. By implementing proper cleaning and maintenance practices, you can reduce the chances of odors developing in the first place.
Always wash your wood cutting board with hot, soapy water immediately after use. This will help remove any residual food particles and prevent them from becoming trapped in the wood. Use a brush or sponge to scrub the surface thoroughly, paying extra attention to any crevices or grooves.
Once clean, rinse the board with warm water to remove any soap residue, then dry it with a clean towel. Avoid leaving the board to air dry, as moisture can encourage the growth of bacteria and mold.
To further prevent odors, consider applying a food-safe oil or wax to the wood cutting board regularly. These products create a protective barrier that seals the wood and prevents odors from seeping in. Follow the manufacturer’s instructions for application and reapplication frequency.
What Should You Not Put on a Wooden Cutting Board?
While wood is a durable material, there are some items you should avoid putting on a wooden cutting board to maintain its longevity. These include:
- Raw meat: Wooden cutting boards are porous and can harbor bacteria from raw meat, increasing the risk of contamination.
- Harsh chemicals: Avoid using bleach or other harsh cleaning agents, as they can damage the wood and leave behind harmful residues.
