Cleaning probably doesn’t top your list of favorite things to do, but you might want to put it on there somewhere. Your family’s health could depend on it. Not to be alarmists or anything, but germs are pretty much everywhere in your home. We discovered the places they hide most often, and some of them may surprise you.


Even if you’re a diligent hand-washer while cooking—you are, right?—bacteria may still be spreading throughout your kitchen and beyond. We’re talking salmonella, listeria, E. coli…all microorganisms that can do a lot of damage without being seen (because, you know, they’re invisible). Find out their favorite hiding spots and how to get rid of them.

    • Sink: It’s where all your kitchen dirt goes (we hope). In fact, it’s home to as many as 500,000 bacteria per square inch. Spray it down often, clean out your food trap, and scrub with scouring powder like Bon Ami at least once a week.
    • Cutting boards: Whether you’re chopping meat, veggies or fruit, your cutting board could be Ground Zero for foodborne illness. Prevent cross-contamination by dedicating one board to meats and another to produce. And always wash your board ASAP after using it—especially if you were working with raw meat. Researchers at UC Davis also recommend plastic cutting boards over wood, because they’re easiest to sanitize—they can go in the dishwasher. Clean a wooden cutting board with soap and warm water, dry it quickly, and seal it with butcher-block oil whenever you notice the wood is drying out.
    • Countertops: All the action—chopping, mixing, drink-pouring—happens here, so of course they’re covered with little particles of everything. Some of the items on the counters can get germy too—particularly spice jars. First off, cut the clutter to give crumbs and germs fewer places to hide. Then wipe them with a damp microfiber cloth after every meal.
    • Fridge shelves and drawers: Your refrigerator is home to both raw and cooked foods, and if it’s disorganized, they probably come in contact now and then. Store raw meat in a plastic bag to serve as an extra barrier, and stop spoiled food from turning into science experiments by throwing it away as soon as you notice it. Another cool trick we use at our house: Empty and wipe down the shelves and drawers whenever you do a big grocery shop.
    • Sponges: They’ve been banned from commercial kitchens—ban them from yours, too. But if you must use a sponge, rinse it with hot water after every swipe. At the end of every day, get it wet and nuke it in the microwave for a minute. Toss it after a few weeks (one week if you’re missing the daily sanitizing routine).
    • Dish towels: If you rush through washing your hands, some germs may still be hanging out on them and you’ll transfer those germs to the dish towel. Change dish towels a few times a week, and wash them with hot water when you do the laundry.


It’s simultaneously the place where you go to get clean and to do your business—whose idea was that, anyway? Meaning, if you want to be clean-clean, you should pay extra attention to these areas of the loo.

    • Towels: Like dish towels, they pick up any germs left after a shower. Plus, if your bathroom has poor air circulation, towels may get musty if they stay damp too long. Wash them in hot water at least once a week.
    • Makeup brushes: They touch your face every day, coming in contact with oils, bacteria and dead skin cells. Wash them with mild soap whenever you notice makeup buildup.
    • Tub: The equivalent of the kitchen sink for your bod, the tub takes in a lot of grime. Wipe it down with a microfiber cloth every day and get rid of mold spots with baking soda or vinegar. (Find dozens more ways to clean with baking soda here.)
    • Floor around the toilet: It gets splashed, plain and simple. For starters, make sure to put the lid down every time you flush. Clean up noticeable spots right away and scrub with bathroom cleaner at least once a week.
    • Faucet handles: You touch these before your hands are clean. ‘Nuff said. Wipe them down with a damp microfiber cloth.
    • Toothbrush holder: It’s all about gravity: Many of the germs on your toothbrush drip into the holder. Rinse it out daily—do double-duty while you’re brushing your teeth with the other hand. Then sanitize your toothbrush holder in the dishwasher (if it can take it) or give it a good scrub with soap and water.

Everywhere Else

Germs can hitch a ride whenever people move through your home. Here are more spots to clean on the regular.

    • Electronics: Smartphones, keyboards, mice, the remote control (OK, let’s be real: 17 remote controls)—germy fingers come in contact with them all the time. In fact, the National Institutes of Health recently found that cellphones are 10 times dirtier than toilet seats. Wipe them with a damp microfiber cloth as often as possible. Don’t forget to remove any cases so you can clean underneath.
    • Doorknobs, handles and light switches: Even if your hand only touches these items for a fraction of a second, that’s enough time to transfer bacteria. Once again, a quick wipe-down with a damp microfiber cloth will do.
    • Shoe rack: Footwear is a huge culprit for bringing germs into your home, so it’s no surprise that their storage unit is a bacterial breeding ground. Put some elbow grease into cleaning this one and wipe it with bathroom cleaner—you never know what somebody stepped in.
    • Carpets and rugs: Even if you’re using the no-shoes rule, carpets suck up every crumb, dead skin cell and germ that hits them. Vacuum weekly and spritz high-traffic areas with a carpet sanitizer. If you can toss rugs into the laundry, do it.
    • Bags: Your purse holds money (super dirty!) and your kid’s lunch bag holds food (raise your hand if you ever forget to clean it out over the weekend). Follow the manufacturer’s instructions on cleaning these to keep them in the best shape.
    • Toys: No matter whose toys they are—your kid’s or the dog’s—they probably spend a lot of time in somebody’s mouth. Consider what they’re made of, then clean accordingly, tossing them in the laundry, dishwasher, or wiping with a cloth.

If you’re like me, you’re rewriting a cleaning to-do list right now. Prioritize these spots and you’re on your way to a cleaner, safer home. (And if you’re on a roll, consider adding these other spots you’ve probably been missing.)
