Sure, you’re wary of spoiled milk, but many other everyday (non-food) items also go bad over time.

Car seats


A car seat can literally save your infant or child’s life, so you’ll want to make sure it’s installed correctly and that it’s not past its expiration date. Yes, every car seat has an expiration date, and it’s usually printed on the bottom of the seat. The longevity of a car seat varies by manufacture date and brand. For example, Graco and Britax car seats tend to expire after six to ten years, depending on the type of seat you have. Find out why even bottled water has an expiration date.



Your sunscreen might not come with an expiration date, but that doesn’t mean it lasts forever. In fact, experts say that sunscreens are generally effective for only three years, after which they begin to lose their potency. The Mayo Clinic recommends jotting the purchase date on the bottle so you’ll know to toss it when you hit the three-year mark. And some sunblocks do have an expiration date, so check the bottle and be sure to mind the guideline. These are other sunscreen mistakes you don’t even realize you’re making.

There’s nothing wrong with stocking up on motor oil when you see a sale, but be aware that it tends to go south after five years, experts say. At that point, the oil can start to separate and the consistency could change, compromising its performance. Don’t miss these other 30 secrets a car mechanic won’t tell you.

Tea bags

If you drink tea only when you’re sick, the tea bags in your pantry may not be as potent as when they were fresh, experts say. While tea won’t necessarily spoil, it can lose quality after about two years, according to manufacturers. Preserve tea longer by storing it in the freezer. Find out which foods in your fridge have probably already expired.



Don’t bother searching for a tiny date printed on your shades—you won’t find one. But it’d be helpful if you could. In addition to shielding your eyes from the sun’s glare, sunglasses block harmful UV rays that could cause cancer or cataracts. Unfortunately, sun specs become less effective at blocking UV light as time goes on, according to researchers at the University of São Paulo, partly from normal wear and tear that may scratch the lenses.

If you’re crafty or own a home, chances are you have plenty of old paint cans in your basement or garage. You likely won’t see an expiration date on them, but that doesn’t mean you can expect to see like-new results every time you pop the top. In fact, painting experts recommend disposing of any paint that’s been open for two to four years. Unopened, oil-based paint will stay good for about 15 years, and latex-based paint stays good for around ten years. Regardless of time, always toss any paint that’s moldy, dried out, or has chunks in it. On the flip side, these are the foods that will never expire.



Toothpaste is not a good candidate for buying in bulk, although a tube’s expiration date depends on the manufacturer and brand. Colgate toothpastes, for example, are generally good for only two years from the manufacture date. If you’ve got some older tubes, consider using them for household projects like removing shoe scuffs or cleaning your clothes iron.

Bar soap


You expect soap to get you squeaky clean, but it might not do as great a job if it’s past its prime. Some bar soaps have expiration dates, but for those that don’t, experts recommend storing them no more than three years. Signs of a too-old soap bar include dryness and cracks. See these other signs you’re probably showering wrong.

That dark bottle has a surprisingly short shelf life. Unopened, it will be good for about three years, but it loses its effectiveness about six months after you open the lid and expose it to the air. If you’re debating whether to replace your old bottle, pour a bit into the sink; you’ll know it’s still good if it bubbles and fizzes.

Running shoes

Sneakers seen some better days? Time to throw those ratty kicks out. The more you work out in a pair of shoes, the more the cushioning wears down, meaning you won’t be able to run as efficiently and might increase your risk for injury. Most shoemakers recommend replacing a pair after running 300 to 600 miles in them. It’s a wide range, so pay attention to how they feel. Most runners will be able to feel when their shoes have maxed out, Altra shoe developer Golden Harper tells the New York Times.
