In The Kitchen
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. (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.
Clean Appliances: Once a week, shake baking soda on a damp sponge and wipe around the machine's edges to remove stuck-on food or stains.
Disinfect the Disposal: To get rid of odors, drop in a cut-up lemon, some salt and a few ice cubes. The lemon deodorizes, and the ice and salt clean away residue.
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.
