Sanitize the Sink: 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.

Do Dishwasher Duty:: Once a week, shake baking soda on a damp sponge and wipe around the machine’s edges to remove stuck-on food or stains. To clean the inside, run an empty cycle with Dishwasher Magic, a product designed to kill bacteria like E.coli.

Clean as You Go: Linda Cobb suggests filling your sink with hot soapy water as you start dinner. “Place used dishes and pans in the filled sink so they’ll be soaking while you eat,” she says. Also, wipe up any spills immediately—don’t give sauces, oils or spices a chance to sit around.

Zap the Sponge: We all know that sponges can be a breeding ground for bacteria. Disinfect yours every night by squeezing it out and microwaving it on high for a minute. When it’s shredded and smelly, replace it.
