Common Household Items You Should Probably Toss ASAP
What's the shelf life of your mascara? Your toothbrush? And how long does nail polish last? It can be tricky to figure out how long it's safe to use certain products without an expiration date. But it doesn't have to be. Here, health experts share exactly when to toss 18 common household products.
In the Medicine Cabinet
When to toss: Every three to four months—sooner if the bristles look frayed or flare out, says Howard S. Glazer, D.D.S., former president of the Academy of General Dentistry. Always get a new brush after you've been sick since the old one can harbor bacteria and reinfect you. (Related: The Best Electric Toothbrushes, According to Dentists)
When to toss: If the bottle has been opened, after two years. Sealed, it's good for three years. It won't look or smell different, but the alcohol evaporates quickly, leaving a solution that's too weak to kill bacteria, explains Steve Clement, a pharmacist and spokesperson for the American Pharmaceutical Association. (On that note...does vinegar kill viruses?!)
When to toss: After six months if it's been opened; three years otherwise. To test whether it's still effective: "Pour some into the sink—if it fizzes and bubbles, it's good," says Marc A. Sweeney, Pharm.D., dean of the School of Pharmacy at Cedarville University. Expired hydrogen peroxide is ineffective but not harmful.
When to toss: After two years, unless there's an earlier expiration date on the bottle. Old insect repellent isn't dangerous, just useless, says Jim Baral, M.D., an assistant clinical professor at the Mount Sinai School of Medicine in New York City. (P.S. These 5 bug sprays actually smell good. Truly!)
In the Gym
When to toss: After every 200 to 300 miles if you're a runner. "Running shoes lose half their cushioning after about 250 miles," says Robyn Stuhr, an exercise physiologist and vice president of Exercise is Medicine (EIM) at the American College of Sports Medicine (ACSM). "This puts more stress on your joints, making you more prone to injuries." If you don't run but work out regularly, buy new sneakers every six months.

When to toss: Usually every six months to a year. To preserve the bra's elasticity, wash it in cold water on the gentle cycle and hang to dry. Two ways to tell whether it's too stretched out: if the bra used to stay in place but now rides up in the back or if your breasts bounce around a lot when you jog or jump. A supportive bra protects your breast tissue from stretching and sagging and can also help prevent soreness. (Related: The Best Sports Bras for Every Body Type)
In the Bathroom
When to toss: How long does nail polish last? Well, that depends. Opened bottles, after about two years. Unopened, they can last indefinitely, says Annette Soboleski, a nail technician for polish maker OPI Products Inc. Once a bottle has been opened, some ingredients will evaporate, causing the polish to thicken and separate. To thin the polish and make it last longer, add a few drops of nail lacquer thinner.
When to toss: After 24 months. The consistency and chemicals change over time, and the dye loses its ability to color your hair and may leave splotchy patches, says Marcy Cona, director of education and shows for Clairol Professional.
When to toss: Every three shaves. After this, the blade becomes nicked and can cut your skin. Bacteria can also develop, causing a rash or other skin irritation, says Debra Jaliman, M.D., a clinical instructor at the Mount Sinai School of Medicine. Change the blade weekly on non-disposable razors.
When to toss: After three or four weeks. Bacteria can build up in the crevices and infect you via an open cut or acne, says Birgit Toome, M.D., a cosmetic dermatologist in New Jersey. Plus, a loofah loses its ability to slough off dry skin after a few weeks. Mesh puffs are more resistant to bacteria and can last for eight weeks. (Speaking of scary skin, this is the best skin-care routine for dry skin.)
When to toss: Opened, after one year. Unopened, after two. Over time, bacteria can grow and cause a rash or infection, explains Dr. Jaliman. (This is more likely with jars, since your fingers can introduce bacteria into the container.) Moisturizers with added ingredients like alpha hydroxy acids pose an additional risk because they can become more concentrated and irritate skin. (Related: The Best Moisturizers for Every Skin Type)
OTC Acne and Skin Creams
When to toss: After two years; sooner if you notice a change in color, consistency, or smell. Expired acne and skin creams are ineffective, because the active ingredients can break down and evaporate, says Dr. Baral.
When to toss: One year from the date of purchase, or after the expiration date. "The chemicals in the lotion that block the sun decompose, making it ineffective," says Dr. Jaliman. (Stock up on these streak-free, non-greasy sunscreens.)
When to toss: Every three months. Bacteria that can cause pink eye (conjunctivitis) or styes can fester inside the tube, says Anne Sumers, M.D., a spokesperson for the American Academy of Ophthalmology. (Speaking of eye health, learn more about Lumify eye drops—and if they're actually safe.)
In the Kitchen
When to toss: Ideally, after just one use, since it's a breeding ground for bacteria, says Michael P. Doyle, Ph.D., a chemistry professor at The University of Texas San Antonio. You can extend your sponge's life by moistening it and heating it in the microwave for one minute to kill germs. Your safest bet, however, is to clean up any kitchen spills with paper towels.

Opened Jar of Tomato Sauce
When to toss: After four or five days if it's refrigerated. Within a week, mold will form and you could get a gastrointestinal illness from the bacteria, according to Kathleen Zelman, R.D., a spokesperson for the American Dietetic Association.
Opened Bottle of Salad Dressing
When to toss: After three to four months for oil-based dressings; three to four weeks for egg or cheese-based ones. Both develop bacteria over time that may cause gastrointestinal upset or food poisoning. (Try these 3-ingredient salad dressings when you need a quick fix.)
