Summarize:

Baking soda absorbs and neutralizes all kinds of unpleasant smells and is a great ingredient to get rid of unwanted garlicky odors that may have been worked into a cutting board or other kitchen utensil. Combine the baking soda and water in a small bowl. Stir them together with a spoon until a thick, grainy paste forms. If not all of the baking soda is absorbed into the water, add a few more drops. If you’ve used, for example, a cutting board or measuring spoons with garlic and they still smell, try getting the smell off with the baking soda paste. Scoop the paste onto the surface of the utensil. Rub the paste into the object. Do this for 1–2 minutes to make sure that the baking soda paste eradicates all of the garlic odor. Some kitchen utensils may have the smell of garlic deeply engrained in them. In this case, if you have a lemon on hand, try cutting it in half and using half the lemon to rub the paste into your garlicky kitchen utensil. The lemon’s acidity will help further neutralize the garlic odor. Turn on your kitchen sink’s tap and hold the cutting board, measuring spoon, or other kitchen item beneath the running water. Rub 1 hand back and forth across the paste-covered surface until you’ve rinsed off all of the paste. Set your utensil in a drying rack and give it 2–3 hours to dry. Once it’s dry, sniff the cutting board. The unpleasant garlic smell should be gone! If you’re out of baking soda, vinegar works equally well as a deodorizer. You can use it to clean the same items that you can clean with baking soda. Just pour a little vinegar onto a clean sponge and scrub it across the surface of whatever kitchen items have an unpleasant garlicky smell. This works well on plastic cutting boards, frying pans, silverware, and even your stovetop. Also try pouring vinegar into a plastic spray bottle and spritzing it across larger items that smell like garlic. This works well for larger cutting boards and stovetops.
Make a paste of 3 parts baking soda and 1 part water. Rub the baking soda paste onto utensils that have a garlicky smell. Scrub the paste in with a lemon for particularly resistant garlic odors. Rinse the kitchen utensil clean with cold water. Scrub garlicky items with vinegar if you don’t have baking soda.
