The fruit salad, just cut from fresh fruit, smells slightly of onions or garlic? No way! But who wants to arrange and use a whole row of chopping boards separately for each application with the utmost discipline to avoid unwanted flavour transfer? Fortunately, there are two methods that work well to remove unwanted odours from chopping boards. The first: rub the board vigorously with plenty of sea salt and half a lemon, leave it on for 20 minutes and then rinse it off with cold water. The second, even more effective method is to mix 3 parts baking soda with 1 part water to make a paste, rub it into the board and then rinse it off with cold water.
