Many everyday items have hidden expiry dates that can affect their quality and safety over time. From household products to personal care items, knowing when to replace them can help maintain their effectiveness and keep you healthy. Here are some surprising items you might not realize have expiry dates.
Batteries
Batteries, especially alkaline ones, have a shelf life of about 5 to 10 years. Over time, they can leak and lose their charge, which can damage your devices. Rechargeable batteries also have a limited number of charge cycles before they become less efficient.
Toothpaste
Toothpaste typically expires after two years. The fluoride in toothpaste, which helps protect against cavities, can degrade over time, making it less effective. The consistency and flavor can also change, making it less pleasant to use.
Sunscreen
Sunscreen has a shelf life of about three years. After this period, the active ingredients can break down, reducing its effectiveness in protecting your skin from harmful UV rays. Always check the expiration date on the bottle.
Spices
Ground spices generally last about three to four years, while whole spices can last up to four years. Over time, they lose their potency and flavor. Storing them in a cool, dark place can help extend their shelf life.
Bleach
Bleach loses its effectiveness after about six months. Its disinfecting properties degrade over time, making it less effective at killing germs and whitening clothes. Store it in a cool, dark place to maintain its potency.
Medications
Most medications have an expiration date, usually ranging from one to five years. After this date, they can lose their effectiveness and potentially become harmful. Always check the expiration date and dispose of expired medications properly.
Contact Lens Solution
Contact lens solution expires after about three months once opened. Using expired solution can lead to eye infections as the disinfecting properties diminish over time. Always check the expiration date and store it in a cool, dry place.
Perfume
Perfume typically lasts about three to five years. Over time, the fragrance can change due to oxidation and exposure to light. To extend its life, store it in a cool, dark place and avoid exposing it to air for extended periods.
Cosmetics
Makeup products have varying shelf lives: mascara (three months), foundation (six months to one year), and lipstick (one to two years). Using expired cosmetics can lead to skin irritation and infections. Always check the packaging for specific expiration dates.
Vitamins and Supplements
Vitamins and supplements usually expire within two years. After this period, their potency can decrease, making them less effective. Store them in a cool, dry place and check the expiration date before use.
Shampoo and Conditioner
Shampoo and conditioner generally last about two to three years. Over time, the ingredients can break down, reducing their effectiveness. If the product has changed color, consistency, or smell, it’s time to replace it.
Canned Goods
Canned goods can last for several years, but they do have an expiration date. Over time, the quality and nutritional value of the food can decline. Always check the date on the can and store them in a cool, dry place.
Motor Oil
Motor oil has a shelf life of about five years. Over time, it can degrade and lose its effectiveness in lubricating and protecting your engine. Always check the expiration date and store it in a cool, dry place.
Cleaning Products
Most cleaning products have a shelf life of about two years. After this period, their effectiveness can diminish. This includes items like dish soap, disinfectant sprays, and laundry detergents. Check the expiration date and store them properly.
Toothbrushes
Toothbrushes should be replaced every three to four months. Over time, the bristles can become frayed and less effective at cleaning your teeth. Additionally, bacteria can build up on the toothbrush, leading to potential health issues.
Chopsticks and Wooden Utensils
Chopsticks and wooden utensils can develop cracks and harbor bacteria over time. It’s recommended to replace them every one to two years, depending on their condition. Regular cleaning and proper storage can help extend their life.
Dish Sponges
Dish sponges should be replaced every two weeks. They can harbor bacteria and mold, which can be transferred to your dishes and kitchen surfaces. Regularly disinfecting them in the microwave or dishwasher can help, but replacement is still necessary.
Smoke Detectors
Smoke detectors have a life span of about 10 years. After this period, the sensors can become less reliable. Regularly test your smoke detectors and replace them as needed to ensure they function properly in an emergency.
Running Shoes
Running shoes typically last about 300 to 500 miles. Over time, the cushioning and support can degrade, increasing the risk of injury. If you notice signs of wear, such as uneven tread or decreased comfort, it’s time to replace them.
Fire Extinguishers
Fire extinguishers have a life span of about 5 to 15 years, depending on the type. Regularly check the pressure gauge and look for signs of damage or corrosion. Replace them as needed to ensure they are effective in an emergency.
Towels
Towels should be replaced every one to three years. Over time, they can become less absorbent and harbor bacteria and mold. Regular washing and proper drying can help extend their life, but replacement is necessary for hygiene.
Non-stick Cookware
Non-stick cookware typically lasts about five years. Over time, the non-stick coating can wear off, making it less effective and potentially releasing harmful chemicals. Replace them if you notice scratches or peeling.
Pillows
Pillows should be replaced every one to two years. Over time, they can lose their shape and support, and accumulate dust mites, allergens, and bacteria. Regular washing and proper care can help, but replacement is essential for a good night’s sleep.
Helmets
Helmets, whether for biking, skiing, or other activities, should be replaced every five years. The materials can degrade over time, reducing their effectiveness in protecting your head. Replace them immediately if they have been involved in an impact.
