Citrus fruits such as lemons, oranges, limes, and grapefruits can appear clean upon purchase, but they may still harbor dirt, dust, germs, and residues from handling. Additionally, some varieties are coated with a food-grade wax post-harvest to maintain freshness. Despite this, cleaning them does not require soap or harsh detergents. A simple rinse and gentle scrub are typically sufficient to prepare these fruits for consumption, whether you intend to eat them whole, cut them, or use their zest. Here’s how to effectively wash citrus fruits before use.
Before washing the fruit, clean your hands with soap and water. There is little point in carefully cleaning a lemon if you immediately handle it with dirty hands. Also make sure your sink, chopping board and knife are clean, particularly if you are going to cut the fruit immediately after washing it. This is where things can get slightly tricky. Some citrus fruits are coated with food-grade wax after harvest. The coating helps reduce moisture loss and can keep the fruit looking fresh for longer. Washing and scrubbing can remove dirt and some surface residue, but it may not completely remove a commercial wax coating. If you specifically want unwaxed citrus for zesting, look for fruit labelled as unwaxed where available. Otherwise, give the fruit a thorough rinse and gentle scrub before using it. Using dishwashing liquid to clean lemons or oranges may seem like an effective way to remove wax, but it is not recommended. Fruit and vegetables should not be washed with dish soap, detergent, bleach or household disinfectants. These products are not intended to be consumed and can leave residues on food. Your citrus fruit does not need to be treated like a kitchen countertop. There is also no need to turn your kitchen into a science experiment every time you wash a lemon. Vinegar, baking soda, salt and other homemade mixtures are popular online, but they are not necessary for routine cleaning. A thorough rinse under running water combined with gentle rubbing or brushing is a much simpler approach. If the fruit has visible dirt, focus on physically removing it rather than trying to disinfect the peel with kitchen ingredients.
