How often should you change your pillow? Or how long is it safe to keep batteries in storage? There are a number of things around the house we probably don’t replace as often as we should.
It can be hard to keep track of when you bought each and every item in your house. Unfortunately, those same items can become a health risk – either as a haven for household germs or as an electrical hazard when equipment becomes faulty.
It can be equally hard to know when to throw things out, so here are five common household items with expiry dates you should be aware of.
The humble kitchen sponge is truly indispensable but can quickly become a hotbed of bacteria. They can house germs for hours, if not days, and can then transfer them to your hands and food.
Boiling or microwaving your sponges after each use isn’t enough to kill the plethora of bacteria found on a sponge and experts say it’s best to replace them once a week.
If you’re like most people, then there are probably extension cords in your home that are older than your pets. But they have an expiry date like anything else, and the risk of electrocution from a faulty cord is always present.
Any sign of wear or cracks on the exterior of an extension cord means it’s time to throw it out. If the plug or prongs feel loose in the socket, this can be a fire hazard.
Inspect cords thoroughly before use, and don’t run one under a rug or overload it with too many appliances.
Most people don’t change their toothbrush as often as they should. The head of your toothbrush is home to more than 10 million bacteria – and not all of them are harmless.
Scientists recommend your toothbrush needs to be replaced at least every three to four months or when the bristles become frayed and worn, whichever comes first.
Batteries often run out long before they become a safety concern, but it’s also not uncommon for people to stock up on batteries, especially if they’re on sale. But there are limits to how long you can keep them in storage.
Unused alkaline batteries will last between 5 and 10 years. Lithium-ion batteries, which power devices such as mobile phones, can keep a partial charge for up to four years before being depleted.
Alkaline batteries are also at risk of leaking if they are left unused in a device. This can happen in as little as six months. Gases build up inside the battery cell, eventually rupturing the outer casing and hydrogen peroxide (HP) leaks out. HP is highly corrosive and can cause serious chemical burns, so proceed with caution when handling leaking batteries.
Resting your head and neck on your pillow night after night can leave it much dirtier than it looks. Your pillow absorbs all the sweat, oil, and skin cells you shed while sleeping.
Experts recommend replacing pillows every one to two years. Doing so helps to make sure your pillow is clean and free of allergens. It is also important to wash pillows regularly, or the safe replacement time is closer to six months.
