How Do You Clean a Smelly Cutting Board?

So, how do you clean a smelly cutting board?

If your board still smells like garlic, fish or raw chicken after washing, the smell is not sitting on the surface. It is trapped in the tiny knife grooves where bacteria and food residue keep building up.

Short answer

The best way to clean a smelly cutting board is with an enzyme-based cleaner, which breaks down the food residue and bacteria trapped in the surface instead of just masking the smell. Spray it on, let it sit for a few minutes, then wipe or rinse clean. The smell lifts because its source is gone, not covered up.

What actually causes a smelly cutting board

Cutting boards look clean far more often than they actually are. Every time you chop, knives cut tiny grooves into the surface, even on plastic boards. Those grooves become a permanent trap for:

• Raw meat and fish residue
• Garlic and onion oils
• Food starches and juices
• Bacteria that feed on all of the above

A quick rinse or wipe only touches the surface. Whatever is sitting inside the grooves stays right where it is, which is why the smell always seems to come back the next time the board gets warm or wet.

Why lemon, salt and baking soda don't fix it for good

Rubbing a board with lemon and salt, or scrubbing it with a baking soda paste, is the advice you'll see most often. These methods can lift some surface odour and even look effective at first.

• They don't reach residue trapped deep in knife grooves
• Their effect fades within a day or two, especially on porous wooden boards
• They rely on scrubbing and abrasion rather than actually breaking anything down
• They do nothing to stop bacteria multiplying again as soon as the board gets wet

They're a quick freshen-up, not a fix for the source of the smell.

Why enzyme cleaners are the best way to clean a smelly cutting board

Enzyme cleaners work on a different principle entirely. Instead of masking odour with acid or abrasion, enzymes digest the organic matter causing it.

Enzymes:

• Break down proteins and oils trapped in grooves and pores
• Target the bacteria feeding on that residue, not just the smell it produces
• Keep working after you've wiped the surface, not just while you scrub
• Are safe to use around food preparation areas when used as directed

That's why they get to the smell that lemon, salt and baking soda only ever cover up.

A simple cutting board cleaning routine

1. Wash the board as normal with warm water and dish soap
2. Spray the enzyme cleaner generously over the whole surface, including the edges
3. Let it sit for 2–5 minutes so the enzymes can break down trapped residue
4. Wipe clean with a damp cloth, then rinse with clean water
5. Stand the board upright to dry fully before storing it

Letting the cleaner sit is the part most people skip, and it's the part that actually does the work.

The Cleaning Enzymes Kitchen Rescue

Our Kitchen Rescue enzyme cleaner is designed for exactly this kind of everyday kitchen problem. It's formulated to break down food residue, grease and organic build-up on benchtops, sinks and cutting boards alike.

Spray, wait a few minutes, then wipe. There's no harsh chemical smell, and it's always best to rinse food preparation surfaces with clean water afterwards, following the label directions.

So, how do you clean a smelly cutting board?

If you want a board that's actually clean, not just freshly rinsed, reach for an enzyme cleaner instead of lemon, salt or baking soda. It breaks down what's causing the smell instead of covering it up, so the fix actually lasts.

Frequently Asked Questions

Why does my cutting board still smell after washing?
Knives cut tiny grooves into every cutting board, even plastic ones. Food residue and bacteria get trapped inside those grooves, where a normal wash with soap and water can't reach them.

Is it better to clean a cutting board with lemon and salt or an enzyme cleaner?
Lemon and salt can lift some surface odour but fade quickly and don't reach bacteria trapped in grooves. Enzyme cleaners break down that residue at the source, so the result lasts longer.

Can enzyme cleaners be used on wooden cutting boards?
Yes. Enzyme cleaners are safe for both wooden and plastic boards. Always follow the label directions and rinse with clean water before preparing food again.

How often should I deep clean my cutting board?
A quick clean after every use is good practice, but a proper enzyme clean once a week helps stop residue building up in grooves before it becomes a lingering smell.

Do enzyme cleaners work on garlic and onion smells too?
Yes. Enzymes break down the organic oils in garlic and onion that cause the smell, rather than masking them, which is why the smell doesn't come straight back.
