You think food's the only stuff that goes bad? Think again! There's all kinds of junk in your proverbial, domestic trunk that can go bad. So unless you want to suffer the consequences, make sure you keep an eye on your expiration dates — even if they're not there.
Are you scrubbing down your body with an impenetrable sun-shield? Or with an ineffectual lather? Because most experts say that sunscreen only last three years. Most sunblocks don't come with expiration dates, but many do — so make sure to check the bottle.
If you're like me, you don't even know what motor oil is. Is there a motor vinegar too? How about a motor caprese? If there's not, there should be. And if there is, mix it with your motor oil and make sure you throw it out after five years. Because that's how long motor oil experts say you a bottle of motor oil lasts.
Tea is so healthy for you... if you drink it on time. And if you don't...?! It's still healthy for you, buuuuuut it just might not have the same potency, flavor, or color that it used to. Like humans, they can grow weak with age. Teas don't expire in the traditional sense, but you'll want to drink them within one to two years for optimal flavor and punch.
Sunglasses aren't magical shields for your eyes — they're very real, very physical shields for your eyes. All those UV rays that hit them could be hitting your peepers, doing damage, causing cancer or cataracts. Now, imagine all the hurt your sunglasses get for their good deeds: they're getting busted up! So pop out those lenses every once in a while.
Paint cans aren't just fun for sniffing fumes, they're used for home crafts, painting, and stuff like that. You're not likely to find expiration dates on those cylinders. But an unopened paint can is usually only good for about 15 years. And once opened, it will last 10 with the top still on.
Bars of soap clean you... but are they keep cleaning themselves? When was the last time you saw a boar of soap wash itself? What does it do all day in the shower when you're at work? Grow mold? Decompose? It expires, is the answer. After about three years, on average, experts say. And if it takes you three years to go through a bar of soap... consider cleaning more often?
Batteries are stores of energy, but they work on very intricate chemical circuits. Alkaline batteries (alkaline based) last about seven years unused. Lithium batteries last about 10 years unused. And the Tesla Powerwall? Who knows.
Look at that sexy piece of safety machinery. Fire engine red, without the fire... yet. If you don't use and replace your fire extinguisher every year at a drunken Thanksgiving to put out Uncle Timothy's toupee, then at the very least you should replace it every six years. Also, Timothy should just go au naturale, no? What do you think?
This seems a little excessive, but maybe that's because I don't brush my hair like some blessed Samson of the Old Testament. You should clean your hairbrush once a week, and replace it every six to 10 months. Because it picks up a lot of oils and other gunk, and then things live on those little needles, and then you put that back on your head, and then you get the picture.
Whether you have a child, or whether you use these bad boys for dropping Molly, either way: you're going to want to replace them every two to five weeks. The latex will break depending on how hard your child (or you) chomp down. And then the moisture that gets on them will serve as a breeding ground for bacteria.
Towels are meant to help you clean, not spread diphtheria or yellow fever! Even if you wash them regularly (which you def should) they can still serve as a substrate to all kinds of bacteria looming in your bathroom. Bath towels expire after three years, MAX! So dump that stuff.
The bra is a piece of equipment that can lose its form and function after use, too. After about one to two years, the bra will lose its shape, become deformed, and might even hurt. It's not YOU! It might just be your bra.
The astringent antiseptic hydrogen peroxide is only good for six months after you open it. However, an unopened bottle can last you a good three years. If you're not sure if it's good or not, try this trick: dump some in the sink. If it sizzles and fumes, it's still good. If it doesn't, it's gone bad. And if it blows the sink up... it's not hydrogen peroxide.
Slippers are so cute, and also so disgusting. That material, even if washed, can harbor germs and other ill-making agents. Make sure to toss your furry bunnies every six months. Don't worry — they don't feel anything. Except pain.
