If you’re brushing in the morning and the evening like you’re supposed to, then your toothbrush bristles are probably becoming frayed and worn faster than you realize. “In my experience, bristles start to fray after about two months of use, so I recommend my patients replace their brushes every three months,” says American Dental Association spokesperson Ruchi Sahota, who is a practicing dentist in California. Worn-out brushes are less effective at cleaning teeth and fighting off decay.
Toilet Brush
Toss it (regularly). “This household cleaning hero is often ignored until the bristles fall out or stains and smells become intolerable,” notes Cohen. While the brush can be cleaned with bleach, you should still probably be replacing the toilet brush more often than you think. If cleaned with bleach regularly, replace it annually. If you don’t bleach it, replace it every 6 months or any time a gastrointestinal illness crosses your bathroom threshold.
Lingering leftovering
When it comes to highly perishable food that contains animal ingredients, the rule of thumb is to eat, toss, or freeze after three days, says Michael P. Doyle, PhD, director of the Center for Food Safety at the University of Georgia. “Listeria is linked to scary things like meningitis, miscarriages, and even death,” he says. “It can grow to millions at refrigerator temperatures in under a week.”
Plastic cutting board
Slicing and dicing on plastic cutting boards scores the surface (those lines you begin seeing after the first few times you use one). Once bacteria get into these tiny grooves and begin to grow, they can be very difficult to get rid of, says Doyle. He recommends switching to wooden cutting boards because wood contains resins that are naturally antimicrobial. Translation: when you score a wooden cutting board and bacteria seeps in, it dies instead of thrives
Stale spices
Spices that have been hanging out in your cabinets for years probably won’t make you sick—but they won’t add any flavor to your food, which is key when you’re trying to cook healthy meals that don’t go overboard on fat or calories. Fresh spices can mean the difference between bland meals that makes you consider giving up on your goals and ordering delivery, and amazingly flavorful food that’s good for you and satisfying.
Moldy Shower Curtain
Clean it! “Add a dirty shower curtain to your washing machine with detergent and a towel for scrubbing action,” says Cohen. “For higher-quality shower curtain liners, this tip can work numerous times.” Once the liner shows serious signs of wear, you’ll know it’s time to replace it.
Your kitchen sponge
Studies show the kitchen sponge is the germiest thing in the average American household, says Tierno. While some experts recommend microwaving sponges daily to zap bacteria, Doyle recommends skipping them completely: “When you use a sponge to clean meat juices, which can contain harmful microbes like salmonella, and it stays moist at room temperature, they grow quickly and studies show even the dishwasher doesn’t kill them.” He advises using a washcloth to clean dishes instead, grabbing a clean one every few days, and throwing the dirty ones in with your laundry. “Because it’s thinner, a washcloth dries quicker than a sponge between washes, which helps significantly slow bacterial growth,” he explains.
Your chair
Global studies show that the average person sits 7.7 hours a day, and some estimate people sit up to 15 hours a day, says Robert Emery, professor of occupational health at the University of Texas School of Public Health. Excessive sitting impacts the body’s metabolic system, and can lead to obesity, high blood pressure, diabetes, cancer, and depression. But it’s not as simple as putting in more time at the gym, which may not even reverse “sitting disease,” adds Emery. The American Medical Association recommends switching to a standing desk for work as an excellent way to combat the health issues associated with too much sitting.
Old sunscreen
When it comes to sunscreen, the expiration date really does matter, says Beth Lange, PhD, chief scientist at the Personal Care Products Council. The chemicals that block the sun break down over time, so no matter how much you slather on, it’s not going to protect your skin from aging or cancer risk.
Old lip gloss
Anything that’s used around your mouth collects a lot of bacteria quickly, and the longer the bacteria sits in a moist tube, the more it grows. This increases your chance of infection if it gets into a cut or crack on the delicate skin of your lips. For this reason, experts recommend that you throw out lip gloss or other lip makeup no more than six months after you open it and begin using it, or by the expiration date, whichever is sooner.
Stetched-out bras
When’s the last time you went bra shopping? The elastic in bras can get stretched out over time (the washing machine speeds up this process) which means less support for your girls. “Replacing a bra whenever it no longer lends comfort and support will help reduce back pain in heavier women, and can slow the natural process of aging in breast tissue,” says breast specialist Kristi Funk, MD. (That “natural process of aging” is sagging.)
Clothes you don’t wear anymore
Take a peek in your closet. How many items have you not worn within the last year? Many people who’ve lost weight keep the bigger sizes around in case they regain it, while others hold onto the size 2 jeans they wore in high school, thinking maybe if they diet they’ll fit again. In either case, seeing these items every day can bring on anxiety, and that’s not how anyone wants to feel when getting ready.
Old plastic containers
Go through your collection of food-storage containers and toss anything made of clear, rigid plastic, and stamped with a 7 or “pc” (stands for polycarbonate). “These are the types of containers that may contain BPA,” says Sonya Lunder, MPH, a senior analyst at the Environmental Working Group, who also advises tossing warped or cracked containers. While manufacturers have taken BPA out of many of the newer polycarbonate containers, old ones still probably have it. And multiple trips through the dishwasher can up leeching of the chemical. Lunder also cautions against heating any type of plastic in the microwave because of chemical-leeching concerns. “Glass is safer in general,” she says.
Air fresheners
Though some companies have recently announced they’re phasing out phthalates, which are used to help fragrance linger longer, many air fresheners (solids, sprays, and plug-ins) still contain this type of chemical, which in large doses may have harmful effects on reproduction or development. “These products are simply chemical perfumes that you put in the air,” says Lunder, who argues that it’s much healthier to take care of the root cause of a smell than mask it with chemicals.
Worn-out running shoes
Most running shoes should be replaced every 300 to 400 miles, says Jason Karp, MD, exercise physiologist and author of Running for Women. For a runner who logs 30 miles a week, that’s about every three months. When shoes wear down, they lose their cushioning and are less capable of absorbing the impact of your foot landing with each step, so more force is transmitted to muscles, bones, and tendons, putting you at risk for injuries, he explains. If you’re not a runner, replace them about every six months, or as soon as you notice that the tread is looking worn out.
