30 Household Items That Can Become Harmful Once They Expire

There are certain household products that we may believe can last for years without going bad, but the truth is that all products have an expiration date. Be it dried foods, such as herbs, spices and sugar, or cleaning products, such as bleach and detergent, they all come with a “best before” date stamp on their packaging. We shouldn’t risk our health by using expired products. Take a look at these 30 household items that you should know can go bad after a while, even when they smell and taste the same.

Even devices like washing machines and dishwashers need to be replaced after a couple of years, simply because they deteriorate and can no longer guarantee full sanitization of our cutlery and clothes. Once machines become breeding grounds for bacteria, it’s time to think about getting a new one.

There are many products that, because they’re used in damp and warm environments, like the kitchen or bathroom, can start growing germs and bacteria. Items such as towels and sponges can house bacteria that can have negative effects on your health. Take a look at these 30 household items that you should know can go bad after a while, even when they smell and taste the same. Cleaning products can appear ok, but not sanitize properly anymore, etc.

Canned Food

Even though canned foods seem to last forever, we should pay attention to their expiring dates nonetheless. They need to be stored properly in a cool and dry place without much temperature change.

Throw out all cans that start getting rusty or that have started to bulge; the chemistry of the contents has been altered, and they are no longer safe for consumption. Also, acidic foods like tomatoes have a much shorter lifespan than, say, canned corn. 

Cleaning Products

It may surprise you to know that cleaning products degrade over time and that makes them less effective as a result. With time, the plastic bottle containing the bleach will start affecting its formula, rendering it useless.

This applies as well to laundry and dishwashing detergents or furniture and window cleaners. These products kill germs and bacteria and are fundamental in the sanitization of our house, therefore we need to bear in mind their expiration date.

Cooking Oil

Just because cooking oil doesn’t change color or smell over time, that does not mean it’s still good to consume. In most cases, vegetable oil is ok for human consumption for up to six months after it’s been opened. 

ADVERTISEMENT

If you dare ingest it after that period of time is over, you are putting your health at risk. It can cause gastrointestinal distress, such as nausea and abdominal pain, and facilitate growth environments for bacteria.

Toiletries

Toiletries such as shampoo, conditioner or deodorant have a finite lifespan that you should pay attention to. Once expired, they can simply not be as effective as they used to be, but this is a best case scenario. 

ADVERTISEMENT

There is a fair chance that they will irritate your skin and cause you discomfort. Be careful of expired face products that can cause skin rashes or even infections. Don’t underestimate the expiring dates of these products.

Disposable Razors

Disposable razors should be discarded after a maximum of 10 shaves. With each shave, the razor loses sharpness, becoming less effective. They also are in contact with soap and water, which can lead to a rusty blade.

ADVERTISEMENT

This can cause what we typically call a “razor burn.” You repeatedly go over the same patch of skin since it’s not shaving properly anymore. It can cause skin irritation, nasty rashes, ingrown hairs, and even accidental cuts.

ADVERTISEMENT

Cosmetics

It’s well researched that expired cosmetics can be harmful to your skin, but also makeup brushes and other tools can become a seedbed for bacteria. It’s recommended that you regularly clean your brushes and sponges or even replace them if necessary. 

ADVERTISEMENT

You will avoid outbreaks, rashes, and irritation by keeping your tools sanitized. Be extra careful with mascara because the wand can become a breeding ground for bacteria that can cause eye irritation, among other things.

Bike Helmet

In case you didn’t know, helmets used to protect the head from traumatism in an accident do expire! Over the passing of time, the integrity of the cushion and protective elements inside the helmet start getting altered, making it less effective.

ADVERTISEMENT

If your helmet was involved in an accident or if it’s been damaged, go ahead and replace it. If your helmet doesn’t fit properly or if it’s over five years old, change it as well.

ADVERTISEMENT

Sponges

It’s very important that you regularly renew kitchen and shower sponges to avoid them becoming a cradle for bacteria. Sponges are more prone to developing bacteria because they’re being used in warm and wet environments. 

ADVERTISEMENT

An old sponge used in the kitchen can risk your health, you could contract salmonella or E.coli. Depending on how much you use them, change the kitchen sponge once a month. The shower sponge can last a bit longer.

ADVERTISEMENT

Pillows

When was the last time you replaced your bed pillows? Even though they might be in very good conditions, pillows should be replaced every 3 years. With the passing of time, pillows can start housing dust mites that cause eye infections and allergies. 

ADVERTISEMENT

Also, you will notice that the shape has started to warp, and it can cause you severe neck pain and many restless nights. Fortunately, pillows are relatively cheap and easily accessible. 

ADVERTISEMENT

Toothbrushes

Although made of synthetic fibers, toothbrushes also expire after a while, and it’s very important to throw them away when they do. They can become a breeding ground for bacteria, leading to mouth infections of various kinds.

ADVERTISEMENT

Replace your toothbrush every three months as indicated on its package. But also, it’s important you replace it after recovering from an illness, such as a cold, because germs and bacteria can linger, and you risk getting sick again.

Shower Curtains

Shower curtains, while seemingly simple, have a finite lifespan. They are constantly exposed to moisture and humidity, making them prime targets for mold and mildew growth. Although regular cleaning can extend their life, the material can degrade, leading to tears or an unpleasant odor. Plastic liners especially can harden and crack over time.

Additionally, with frequent exposure to various body products and water, discoloration can occur. It’s advisable to replace your shower curtain once it starts showing signs of wear or becomes difficult to clean. Some even opt for periodic replacements to ensure a fresh, mold-free environment in their bathrooms.

Hair Straighteners

Like many electronic beauty tools, hair straighteners don’t last forever. With frequent use, their heating elements can degrade, leading to uneven temperatures and potential hair damage. The protective ceramic or tourmaline coating can wear off over time, resulting in a less smooth glide and increased friction, which can pull or break hair.

Additionally, old or damaged straighteners might pose a burn risk or an electrical hazard. If you notice your straightener isn’t heating as effectively or the plates look worn out, it’s wise to replace it. A quality straightener, if used and stored properly, should last several years.

Bras

Integral to many wardrobes, bras offer both support and contouring. However, like most apparel, they aren’t forever pieces. With time, the fabric’s elasticity weakens, resulting in a less snug fit. Components like hooks can lose their shape, underwires might poke out, and straps can stretch out.

Moreover, due to the regular friction from wear and the effects of washing, the material can wear thin or develop imperfections. While a bra’s longevity can vary based on usage and care, for maintaining the best comfort and support, it’s advisable to consider replacing bras every 1-2 years.

ADVERTISEMENT

Sandals

Believe it or not, even your sturdy sandals have an expiration date. Over time, the cushioning can wear down, and the soles may lose their grip, leading to a less comfortable and potentially unsafe footing. If you notice the tread on your sandals has smoothed out, it’s time to start shopping.

Similarly, if the straps are frayed or the buckles are no longer secure, your sandals are telling you they’ve trekked their last mile. To ensure your safety and comfort, experts recommend assessing your sandals each season. A fresh pair not only supports your feet better but also maintains the health of your posture and joints. So give your faithful footwear a check-up and ensure you’re stepping out in safety and style.

Coffee

Coffee, the beloved beverage of many, does indeed have a shelf life. While it doesn’t spoil like perishable food, coffee’s optimal flavor can diminish over time. Whole beans maintain their freshness for about a month after roasting, offering the pinnacle of flavor when used within this window.

Once ground, the coffee begins to oxidize faster, and its aromatic oils start to dissipate; thus, it’s best enjoyed within a week or two. To extend your coffee’s lifespan, store it in an airtight container away from light, heat, and moisture. Remember, the fresher the coffee, the more exquisite your cup. So, for the sake of taste, keep an eye on your coffee’s age and savor each brew at its best.

Spices

Spices and herbs are used to season food and can be found in almost all kitchens. These trusty dried foods tend to last longer than any other foods, but that doesn’t mean they don’t expire as well.

ADVERTISEMENT

Consuming outdated spices isn’t necessarily harmful, but they won’t taste as strong and tasty as before. Herbs and spices can last between 1 and 3 years, so clean up your spice rack of old products every now and then.

ADVERTISEMENT

Olive Oil

Olive oil, a kitchen staple, doesn’t last indefinitely. Its quality deteriorates over time due to exposure to air, light, and heat, leading to a rancid taste and reduced health benefits. Ideally, olive oil should be used within 18 to 24 months from bottling and within six months after opening.

Signs of spoilage include a bitter taste or an off smell, indicating it’s time to discard the oil. To maintain its quality, store olive oil in a cool, dark place in a dark-colored bottle. Monitoring its freshness ensures you enjoy its full flavor and health advantages, enhancing your culinary creations.

Frying Pans

You might think that buying frying pans is a once-in-a-lifetime investment, and then you are good to use them for the rest of your life. Did you know that pans have a limited time of use? Experts say that pans should be replaced every 3-5 years.

Non-stick pans have a Teflon coating that will start to peel off eventually, and while it’s not harmful in small amounts, it isn’t necessarily healthy either.

Glassware

Cracked glassware is a common sight in many households, often dismissed as a mere cosmetic flaw. However, the risks associated with using cracked glasses go beyond aesthetics. Firstly, a crack compromises the structural integrity of the glass, making it more susceptible to breaking. This can happen unexpectedly, potentially causing cuts and injuries. Moreover, handling these glasses becomes increasingly risky over time, as even a slight pressure or change in temperature can cause them to shatter.

The second concern with cracked glassware is hygiene. Cracks, no matter how small, are breeding grounds for bacteria and mold. These microorganisms can lodge deep within the crevices, away from the reach of regular cleaning. This hidden accumulation poses a health risk, especially when the glassware is used for consuming beverages. Continual use of such glassware can lead to ingestion of these harmful bacteria, potentially causing health issues. Therefore, cracked glassware should be seen not just as a flawed item but as one that has reached its expiration date for safe use.

Microwaves

Microwaves are a staple in modern kitchens, prized for their convenience and speed. However, like any appliance, they have a lifespan after which their efficiency and safety can be compromised. The first sign of an aging microwave is often a decline in cooking performance. This can manifest as uneven heating, longer cooking times, or a noticeable reduction in power. These symptoms indicate that the microwave is working harder to achieve the same results, leading to increased energy consumption and potential overheating.

The second, more critical concern with aging microwaves is the deterioration of their safety features. Over time, the seals and door hinges can wear out, leading to potential leaks of electromagnetic radiation. Furthermore, the insulation of the electrical components can degrade, posing a risk of electrical fires or shocks. Regular maintenance and monitoring are essential, but there comes a point when replacing the microwave is not just about ensuring the quality of your food but also about safeguarding your home and health. Recognizing the expiration date of a microwave is key to maintaining a safe and efficient kitchen.

Dishware

Old dishware often tells a story of countless meals and memories, but it can also reach a point where it’s best retired. Prolonged exposure to moisture, especially when left to soak in dirty water, can cause significant damage over time. This continuous soaking can lead to the degradation of the material, making it more susceptible to harboring bacteria and mold.

These health risks are especially concerning in porous materials like ceramic or stoneware. In addition, the structural integrity of the dishware can be compromised, increasing the likelihood of breakage. To ensure hygiene and safety, it’s advisable to replace old dishware that has frequently been subjected to such conditions.

Dishwasher

Although they are appliances, they don’t last forever. Our dishwasher can still work wonderfully after a decade of use, but you will notice it becoming rickety and finicky. Dishes can appear clean when they’re actually not, giving way for bacteria to gather.

ADVERTISEMENT

Pay attention to the glasses and see if they come out crystal-clear or if limescale has become impossible to remove with regular descaling products. Those are signs that you need to replace your dishwasher.

ADVERTISEMENT

Slippers

There is nothing better than owning a comfy pair of slippers to walk around the house in, but unfortunately, they need to be let go after a while. They gather not only dirt at the soles but also sweat and dead skin that comes from the feet.

ADVERTISEMENT

They aren’t usually washed in the washing machine because they would get ripped apart. It’s best practice to replace your slippers every 6 months to maintain good foot health.

ADVERTISEMENT

Flour

Flour is one of those essential foods that most people have a packet of somewhere in their cupboards. But if you aren’t a baker or an avid cook, you might forget about that flour you opened months ago. First-grade flour lasts for about 6 months, while other high-grade flour can last up to a year.

In fact, mold, spores, flour moths, and mites, among other insects, can start growing in the flour after a while.

Bug Spray

Depending on where you live, summertime can be impossible to survive without bug spray. We need this product to protect ourselves from mosquito bites and other insects. But bear in mind that bug spray can age and, in turn, become ineffective. 

ADVERTISEMENT

Throw out any bug spray that is over 2 years old, even if the container has some product in it still, because the chemicals change and it just stops working properly or causes skin irritations.

ADVERTISEMENT

Towels

Depending on how often you use your towels, they need to be replaced every 1-3 years at the least. These pieces of cloth are in the damp and warm environment of the bathroom, and they become the seedbed for bacteria growth. 

ADVERTISEMENT


Even high-temperature washing cycles can’t completely get rid of all resilient germs. They also lose fluffiness and become scratchy with time.

ADVERTISEMENT

Pacifiers

Pacifiers are a parent’s best tool to get their babies and toddlers to calm down and sleep, thus getting themselves a good night’s sleep as well. But although your kid might have a favorite pacifier, it should be thrown away every 2-5 weeks. 

ADVERTISEMENT

This is because, with time and use, the latex of the pacifier will crack and become the perfect sport for bacteria to grow. You don’t want to risk your baby getting sick.

Batteries

Batteries come with a “best before” date stamp, which is very important to keep in mind. After a certain amount of time, batteries start corroding and it can lead to battery acid coming out. 

ADVERTISEMENT

This can cause skin irritation, burns, and other negative effects on your health. Check the batteries of your clocks and remotes every few months for corrosion.

ADVERTISEMENT

Keyboard

We use our keyboards every day, therefore we should be cleaning them regularly. But even if we do sanitize them on a regular basis, keyboards should be replaced every 2-3 years.

ADVERTISEMENT

Not only do bacteria grow in between the keys, but also they start to fade or become stuck with time. Like any other device, keyboards also start to deteriorate.

Mattress

A good mattress can tremendously improve the quality of your sleep. Most mattress companies suggest we replace them every 8 years due to them losing their shape and firmness. 

ADVERTISEMENT

This can cause severe neck and back pain as well as bad quality of rest. They also can become breeding grounds for bacteria since we sweat a lot when we sleep.

ADVERTISEMENT

Carpets

If you have carpet on the floor of your home, bear in mind that it should be replaced every 10 years. Even if you clean and vacuum on a regular basis, it might not be enough to keep it free of bacteria after a few years. 

ADVERTISEMENT

Also, you will notice that the fibers break up, and the carpet becomes thinner.

ADVERTISEMENT

Washing Machine

Like the dishwasher, the washing machine is an appliance that can start to fail over time. It’s highly recommended that you replace your washing machine with a new one every 8 years. 

ADVERTISEMENT

It can harvest bacteria and grow mold that can stain your clothes. Save up some money for when the time comes to get a new state-of-the-art machine.

Face Scrub

It’s not hard to accumulate skin care products since new ones come out all the time, and they have cute packaging that you can display in your bathroom. But let’s not forget that these products go bad at some point.

Face scrubs can only last up to a year, so make sure to use them up before buying more.

Shower Gel

If you prefer show gel over soap, you might have more than one bottle lying around your bathroom. They are relatively cheap to buy and come in various colors and scents, which tempts you to buy some every time. 

ADVERTISEMENT

But shower gels can only last up to 3 years, so make sure you use them up before they expire.

Protein Powder

If you are committed to a gym routine to develop muscle, then you must have included protein powder in your diet under a nutritionist’s advice. 

ADVERTISEMENT

If that is the case, then you must go through the tubes of power relatively quickly, but if you consume it every once in a while, it can become stale. They last for up to 2 years.

ADVERTISEMENT

Sugar

Most people buy new sugar once the one lying around the kitchen gets used up. But this food is not everlasting; it needs to be replaced every 2 years due to its quality starting to decline.

ADVERTISEMENT

It can start to taste a bit off, and you will notice that it starts to clump and harden, making it difficult to use.

Hairbrushes

We brush our hair every single day and as often as multiple times a day. We take the hair that gets tangled and builds up every couple of days, but did you know we should actually replace hairbrushes every single year?

ADVERTISEMENT

Unsanitary things such as dead skin, dust, and other pollutant particles can accumulate in the strands of the hairbrush, rendering it unhygienic. Brushes made out of natural fibers should be replaced even sooner, every 7-10 months.

Printer Ink

Depending on how much you use the printer at work or at home, you might be tempted to buy a bulk of cartridges on sale.

While that sounds attractive, take note that if you don’t use them fast enough, they might expire and dry up. Expired ink can ruin your devices, so think twice before buying several at a time.

Cutting Boards

You might have more than one wooden cutting board at home that you use to slice and dice different types of foods. But with time and use, cutting boards become soft, and the cutting knife can create deep scratches. 

ADVERTISEMENT

It can be difficult to remove pieces of food from the crevices with success, giving way to the growth of bacteria.

Toothpaste

Toothpaste usually has a shelf life of two years. The reason for this expiration date is due to fluoride. After two years, fluoride can change in flavor and color, and it may not be as effective, explains Sean Tomalty, a cosmetic dentist.

It is very important to take care of our teeth and do everything we can to avoid any conditions.

Eyedrops

Once you buy them, eyedrops are commonly one of those products that stay in our medicine cabinet for a long time. However, it is little known that they can cause severe damage after 4 weeks.

ADVERTISEMENT

The reason for this is that after 28 days, eyedrops begin to lose their disinfectant component, and using them increases the chance of contracting bacterial infections.

Boxed Wine

We all heard the phrase, “The older the wine, the better they get”. But have you ever wondered how old is too old? When it comes to packaged wines, the recommended consumption time after
purchase is between 6 to 8 months.

ADVERTISEMENT

This occurs because some boxes may contain bisphenol (BPA), a component that can cause heart problems or even fertility difficulties.

Mouthwash

Mouthwash is a great ally when it comes to taking care of our oral health. However, it is important to know that the alcohol component in every mouthwash begins to dissolve after 2 or 3
years.

After this time, it will lose its effectiveness, and it will be necessary to buy a new one to do the trick for us.

Sunscreen

When it comes to sunscreen, it is important to know that most of them have a shelf life of around 3 years.

being protected from the sun effectively.
