Common Household Items That Expire and Should Be Discarded
Many people assume that certain household items are safe to use indefinitely, but in reality, several common products have expiration dates or limited lifespans. Failing to replace these items can lead to reduced effectiveness, potential health risks, or even safety hazards. Here’s a closer look at some of the most overlooked items that should be tossed when they expire.
Cooking Oil
Cooking oil may seem like it lasts forever, but once opened, it can become rancid within a few months. Canola oil typically expires within 6 to 12 months, while olive oil lasts about 3 to 6 months. Although consuming expired cooking oil won’t harm you, it will lose its nutritional value and may start to taste bad.
Fire Extinguishers
Fire extinguishers are one of the most critical safety items in a home, yet many people overlook their expiration dates. Disposable extinguishers last about 12 years, while those that can be recharged need servicing every six years. Check the gauge level; if the needle has fallen below the green zone, it's time to replace it. Proper disposal is essential—empty extinguishers can be recycled, while full ones must go to a hazardous waste facility.
Makeup
Makeup, including mascara and foundation, has a shelf life that varies depending on the product. Open foundation usually expires after six to 12 months, while lipstick and gloss expire after one to two years. Using expired makeup can cause rashes, acne, and even eye infections.
Mattress
A standard mattress has a shelf life of about seven to 10 years, depending on the material. Latex mattresses last about 7½ to 8½ years, while innerspring models only last five to six years. If you're experiencing poor sleep or noticing sagging and odors, it might be time for a new mattress.
Sunscreen
Sunscreen has an official expiration date, typically listed on the bottle. It maintains its original strength for about three years, after which it becomes less effective. If a bottle doesn’t have an expiration date, write the purchase date on it and start the three-year count from there.
Disinfectant
The active ingredients in disinfectants degrade over time, so they should be discarded after their expiration date. According to the American Cleaning Institute, the shelf life of disinfectants typically lasts only a year. Expired disinfectants won’t be as effective, though they aren’t harmful.
Bleach
Bleach has a shorter shelf life than many people realize. An unopened bottle lasts about 12 to 18 months, while an opened bottle only lasts six months. Store bleach in a cool, dry place to extend its lifespan. While expired bleach isn’t dangerous, it won’t be as effective.
Toothpaste
Toothpaste typically has an expiration date set for about two years after the manufacturer’s date. While using expired toothpaste won’t harm you, it will gradually lose its effectiveness at cleaning teeth. Fluoride, a key ingredient, gives toothpaste its drug classification, which includes an official expiration date.
Laundry Detergent
Liquid laundry detergent lasts about six to 12 months after being opened, while an unopened bottle can last up to 18 months. Powder detergent has a longer shelf life, lasting up to two years unopened. Expired detergent won’t be as effective, but it’s not dangerous.
Bottled Water
Even bottled water can expire. While the water itself doesn’t go bad, the plastic container can degrade over time, especially if exposed to heat or sunlight. Microplastics and chemicals can leach into the water. Once opened, bottled water should be consumed within four to six days.
Medication
Medication loses potency over time and can sometimes host bacterial growth. Always check the expiration date before taking any medication. Expired pills may not work as intended, especially in emergencies.
First Aid Kits
First aid kits contain medications and ointments that can lose their effectiveness over time. Adhesives may also lose their stickiness. Regularly check the expiration dates of all items in your first aid kit to ensure it’s fully functional in an emergency.
Lightbulbs
Although lightbulbs don’t have specific expiration dates, they can degrade over time, especially if stored improperly. High temperatures, humidity, and dust can shorten their lifespan. If bulbs show signs of damage, they should be replaced.
Bar Soap
Bar soap typically lasts about three years before losing its efficacy. Even unopened bars can expire after this time. Check the texture and odor before using—any off smell or feel means it’s time to toss the soap.
Hydrogen Peroxide
Hydrogen peroxide breaks down over time, becoming less effective. An unopened bottle lasts one to three years, while an opened bottle lasts six to 12 months. Store it in a cool, dark place to prolong its lifespan.
Power Strips
Power strips can become unsafe over time, especially if they show signs of damage. Replace them every few years to avoid electrical hazards.
Rubbing Alcohol
Rubbing alcohol has a shelf life of about two to three years. Expired rubbing alcohol isn’t harmful, but it won’t be as effective for cleaning tasks or wound treatment.
Spices and Herbs
Spices and herbs lose flavor over time, though they’re not harmful. The general shelf life is one to two years. If your spices smell or taste off, it’s best to replace them.
Paint
Paint types vary in shelf life. Latex paint can last two to 10 years, while oil-based paints can last two to 15 years. If your paint has a chunky texture or smells moldy, it’s time to toss it.
Sponge
Kitchen sponges can harbor bacteria and should be replaced every one to two weeks. If they’re stained, falling apart, or have a foul odor, they should be thrown away immediately.
Dish Towels
Faded dish towels should be replaced or reused around the house. Signs of wear include frayed fabric, foul odors, and decreased absorbency. Experts recommend changing dish towels once a year.
Shower Curtain
Shower curtains should be replaced every year, as they can accumulate bacteria in their moist environment. Fabric curtains tend to last longer than vinyl ones, while shower curtain liners should be replaced every six months.
Pillows
Pillows should be replaced every two years, especially if you suffer from allergies or sensitive skin. They can trap bacteria, allergens, and dust mites, making regular replacement essential.
Shower Poufs
Shower poufs or loofahs should be replaced every three to four weeks. They can easily gather bacteria and mold in a moist environment. Check for any odors or signs of wear and discard them promptly.
