Here’s a safe and natural way to disinfect your kitchen without harmful chemicals: Combine three cups of water, juice from one freshly squeezed lemon and one teaspoon of nonchlorine bleach in a quart-size spray bottle. If you clean with sponges—make sure to regularly replace old ones to avoid spreading bacteria. You can also toss the sponges in the dishwasher for a quick disinfecting wash and rinse!
