It’s hard to believe, but your dirty kitchen sink has more bacteria than your toilet seat. Use a product labeled as an EPA-registered disinfectant, or make your own. To disinfect, clean your sink with soap and water first, then spray a mist of vinegar followed by a mist of hydrogen peroxide, and let air-dry. (Don’t mix the vinegar and hydrogen peroxide together—spray one after the other.) If your sink is stainless steel, make it sparkle afterward by putting a few drops of mineral oil on a soft cloth and buffing. This prevents water buildup, which deters mold and keeps the sink looking clean longer.
