While you’re building your coupon stockpile, make sure you’re rotating things and paying attention to expiration dates.
Some items don’t have expiration dates, but you still need to get rid of them after a certain amount of time.
How can you tell when an item is no longer at its best, or even when it could be dangerous?
Here’s a simple guide to knowing when some of your common household items are ready to be tossed.
1. Power Strips
Not all power strips and surge protectors come with an expiration date on the packaging, but you’ll want to replace even high-quality power strips every year or two.
If they start to discolor or feel hot to the touch, replace them.
Faulty power strips are a leading cause of home fires, and they can fry your electronics if they’re not in top condition.
Your baby’s pacifier should be replaced every two to five weeks.
The latex material breaks down quickly and tiny cracks can create a hiding place for germs.
3. Wooden Spoons
Wood is very porous, which means wooden spoons can retain germs and bacteria like E. coli from raw meats.
Wooden spoons should be replaced after five years (or earlier if the wood is cracked or chipped, providing crevices in which bacteria can thrive).
Believe it or not, the Environmental Protection Agency has set Federal standards for bleach.
After three months, the disinfectant qualities of bleach start to fall below these standards, which means it loses its potency for cleaning but is still effective for household laundry use.
5. Protein Powder
Vitamins and supplements lose potency the older they get.
The expiration date on protein powders is generally one year after its manufacture date, but you can usually get a few more months out of them if they’re stored properly — away from light and heat.
6. Kitchen Sponges
Bacteria, fungi and mold multiply quickly in damp, warm environments, so kitchen sponges are particularly at risk, especially if you don’t let them dry out between uses.
You can disinfect sponges by boiling them, but as a general rule, they should be replaced every two weeks.
Toothbrush bristles become worn down and bacteria can build up over time.
Dentists suggest switching to a new toothbrush every two to three months.
Replace your toothbrush even sooner after catching a cold or flu and especially after strep throat. If you don’t, you could risk getting sick again.
8. Shower loofahs
Like kitchen sponges, shower loofahs — both natural fiber and plastic ones — are a breeding ground for bacteria and mold.
Natural loofahs start to grow bacteria after just a couple weeks of use, while plastic mesh loofahs last up to two months.
9. Lotions and moisturizers
Moisturizers in a tube should last for at least two years after opening, but will eventually dry out and lose their effectiveness.
Lotions in a jar that you use your fingers to apply, like body butter, can easily become a host for bacteria. Make sure your hands are clean when you use jarred lotions, and be sure to toss the tub after one year.
10. Bar soaps, bath gels and body wash
It seems counter-intuitive, but old soaps might not get you as clean as you want to be.
Experts agree that we shouldn’t store soaps, bath gels and body wash longer than three years.
11. Shampoo, conditioner and hair styling products
Hang on to unopened shampoos, conditioners and other hair styling products up to three years.
Once opened, though, these products will only be effective for one to two years.
Not all sunscreens have an expiration date printed on the bottle.
If yours doesn’t, make a note of the purchase date directly on the bottle, and throw it out after three years.
After that, sunblock starts to lose its potency.
Expiration dates for toothpaste vary by manufacturer and brand.
In general, though, toothpaste is good for about two years from the manufacture date.
14. Anti-acne products
Once they’re opened, anti-acne products containing benzoyl peroxide are good for just three months.
Similar products with retinol, glycolic acid and Vitamin C can also deteriorate quickly.
15. Hydrogen peroxide
Most of us keep a bottle of hydrogen peroxide in our medicine cabinets for years.
But once you open a bottle, hydrogen peroxide chemically turns into regular water in only two to three months.
An unopened bottle can last for a year, but should be discarded after that. When hydrogen peroxide loses its fizz, it’s lost its potency.
Whole spices like cardamom pods or cinnamon sticks will begin to lose their flavor in one to three years.
Ground spices have a shorter lifespan, losing their fragrance and flavor after just six months.
When stored correctly — in an airtight container — flour can last six months to a year.
After that, you’ll notice a clear difference in taste.
18. Iodized Salt
Salt in its purest form will last forever, but once iodine is added — as in commonly used iodized salt — it will last about five years.
19. Olive Oil
Two years after its manufacture date, the color or taste of olive oil may change slightly, but it’s still safe to use.
20. Old Potatoes
If you store your potatoes in a cool, dark place, they should be usable for two to three months.
But potatoes contain small amounts of a toxic chemical called solanine that can be dangerous, even fatal if consumed.
When potatoes are fresh, the toxin is minimal, but if potatoes have sprouted or have been exposed to the elements for long periods, the solanine becomes concentrated.
For your safety, throw old, sprouted potatoes into the trash.
21. Disposable razors
Bacteria can build up on razors, and blades can become dull over time, causing razor burn.
To avoid this, replace your razors once a week or after three to four shaves.
An open tube of mascara can start to show traces of bacteria (causing pinkeye and other infections) in a matter of just three months.
A tube of lipstick that’s been opened will last about two years.
After that, you’ll notice the smell and texture of the lipstick will begin to change.
It’s still safe to use, but it may not wear as well as it did when it was new.
While there’s no set-in-stone expiration date for perfumes, they do break down chemically over time, which means the smell will change.
Feel free to wear a perfume as long as you like the smell of it, but here’s the general rule: Perfumes and eau de parfum containing essential oils last three years when stored unopened, and two years after opening.
An unopened bottle of eau de toilette will last four years, and an open bottle will last two years.
25. Bed pillows
Over time, our pillows become home to dust mites and can hold on to other things like dead skin and dust particles.
After years of use, pillows tend to lose their loft, too, and a flatter pillow can lead to neck pain and a poor night’s sleep.
Replace your pillow every three years.
If you wake up most mornings feeling stiff or experience aches, pains or any numbness, it may be time for a new mattress.
Even a mattress that doesn’t show signs of wear and tear, sagging or other damage could be due for an update if you’ve had it for seven years or more.
If your mattress is more than ten years old, it’s time to replace!
Some of us hold on to our bras until the underwire starts poking into our ribs.
But the moment your bra loses its shape or elasticity or isn’t fitting properly anymore, it’s time for a new supportive friend.
If you hand wash and line dry your bras, they should last two years. If you machine wash them, you’ll want to replace your bras every year.
28. Mosquito repellant
The active ingredients in mosquito repellents begin to decay and lose their strength after two years from the manufacture date.
Update your camping supply regularly.
29. Running shoes
Once your running shoes have hit the 250-300 mile mark (generally after about one year of use), it’s time to replace them.
After that, the cushioning begins to break down, and injury to joints becomes more likely.
30. Car seats
Child car seats have an expiration date printed on the bottom or side of the seat (commonly six to ten years after date of manufacture).
Car seats are made from plastic, foam and fabric, which degrade over time — especially with the constant temperature changes inside cars.
Replace your child’s car seat before the expiration date passes, or earlier (like immediately after) if it has been in use during a car accident.
31. Bicycle helmets
Just like car seats, bike helmets become less effective after several years of use, or after any kind of accident.
Replace your helmet every three to five years, or sooner if it’s been damaged.
32. Smoke detectors
Most smoke detectors will have an expiration date or a manufacture date on them.
Even if you replace their batteries yearly, smoke and carbon monoxide detectors can stop working properly after several years.
As a rule, replace them after ten years from manufacture date.
33. Fire extinguishers
The chemicals in fire extinguishers will lose their potency eventually.
Extinguishers also lose air pressure over time.
Most will work well for five to 15 years if there are no cracks in the hose or weak seals on the neck. If you find any of these issues, have your extinguisher serviced as soon as possible.
