Removing the lingering onion smell from a plastic cutting board is a common kitchen challenge, but it can be effectively resolved using simple household items to neutralize the pungent odor and restore freshness.
Eliminate Onion Smell from Your Plastic Cutting Board
Plastic cutting boards can absorb strong odors from ingredients like onions, garlic, and fish. Fortunately, several tried-and-true methods can help you deodorize your board and keep your kitchen smelling fresh.
1. The Power of Baking Soda and Lemon
This highly effective combination utilizes the abrasive and odor-absorbing qualities of baking soda with the natural acidity and fresh scent of lemon.
- Sprinkle generously: Begin by sprinkling a good amount of baking soda directly onto the surface of your plastic cutting board, ensuring a light, even layer.
- Scrub with lemon: Cut a fresh lemon in half. Use the cut side of the lemon to scrub the baking soda into the cutting board. Squeeze gently to release the lemon juice as you scrub, allowing the natural acids to mix with the baking soda.
- Let it sit: Allow the baking soda and lemon mixture to sit on the board for 5 to 10 minutes. This gives the ingredients time to break down and absorb the odor molecules.
- Rinse thoroughly: Wash the board under warm running water, ensuring all the baking soda and lemon residue is completely rinsed off.
- Dry completely: Pat the board dry with a clean cloth or paper towel, and allow it to air dry fully before storing to prevent mildew.
2. Coarse Salt and Lemon Scrub
Similar to the baking soda method, coarse salt acts as a natural abrasive, helping to lift and remove odors from the plastic's surface.
- Apply coarse salt: Sprinkle coarse salt (such as kosher or sea salt) liberally over the cutting board.
- Scrub with lemon: Use a lemon half to scrub the salt into the board. The lemon juice will help activate the salt and add its deodorizing properties.
- Rinse and dry: After a few minutes of scrubbing, rinse the board thoroughly with warm water and dry it completely.
3. White Vinegar Solution
White vinegar is a natural disinfectant and powerful deodorizer, thanks to its acetic acid content.
- Spray or wipe: Spray undiluted white vinegar directly onto the cutting board, or wipe it down with a cloth soaked in vinegar.
- Let it sit: Allow the vinegar to sit on the board for 5 to 10 minutes.
- Rinse and dry: Rinse the board thoroughly with water. The vinegar smell will dissipate as it dries, taking the onion odor with it.
4. Harness the Sun's Power
Sunlight is a natural sanitizer and deodorizer. The sun's UV rays can help break down odor-causing compounds.
- Clean first: Ensure your cutting board is clean and dry after washing.
- Sun exposure: Place the board outside in direct sunlight for several hours. This method works best on a clear, sunny day.
5. Immediate Cleaning with Hot Soapy Water
Preventing odors from setting in is often the easiest solution.
- Wash immediately: After chopping onions, wash your cutting board immediately with hot, soapy water.
- Scrub thoroughly: Use a scrub brush or sponge to clean the entire surface, paying attention to any knife marks where odors can linger.

Prevention is Key
To minimize onion smells in the future:
- Dedicated Boards: Consider having separate cutting boards—one for strong-smelling foods (onions, garlic, fish) and another for milder items (fruits, vegetables, bread).
- Prompt Cleaning: Always wash your cutting board immediately after use, especially after cutting aromatic ingredients.
- Regular Deep Cleaning: Incorporate a deep cleaning routine using one of the methods above regularly, not just when odors are present.
