Secondhand purchases can be smart in a lot of situations, but there are some things that just aren’t worth the risk. Sure, used stuff can save you money, but not if it comes with hidden damage, safety concerns, or just plain grossness. Some items are better off brand new, no matter what kind of deal you find.
Here are 16 things you really shouldn’t even consider picking up used.
Mattresses
Mattresses can be full of things you’d rather not think about. Over time, they collect dead skin cells, body oils, sweat, and – horror of horrors – bedbugs. Even if a used one looks clean on the outside, you never know what’s going on inside. Health and hygiene should come first, so buying a new mattress is always the safer choice.
Helmets
Head protection is something you don’t want to mess with. A helmet that’s been in any kind of impact might look fine but could be structurally compromised, which makes it useless when you actually need it.
Plus, you also can’t always tell how old it is, and materials break down over time. For safety reasons alone, it makes sense to buy a fresh, unused helmet every time.
Makeup
Mascara, lip gloss, and anything else that touches skin or eyes can be a breeding ground for germs. Sharing or buying secondhand cosmetics raises the risk of skin infections and pinkeye, and no amount of savings is worth that. Cleanliness counts more than discounts when it comes to beauty products.
Car Seats
Parents want to keep their kids safe, so using an old car seat just isn’t a good plan. Seats have expiration dates, and older models might not meet current safety standards. On top of that, a used one could’ve been in a crash, even if it doesn’t look damaged. Manufacturers update their designs all the time, so getting the latest version new is the smart move when it comes to protecting your children.
Nonstick Cookware
Pans with nonstick coating wear out faster than people expect. Scratches can release chemicals, especially if they’re older and made with materials no longer considered safe. A secondhand skillet might look okay, but tiny flaws could still cause problems. Replacing these with new ones is worth the peace of mind.
Vacuum Cleaners
Household appliances get worn down pretty quickly, and vacuums take a beating over time. Brushes and motors all wear out, and replacement filters aren’t always easy to find. A used vacuum might seem like a bargain until it stops working or leaves behind more dirt than it picks up. Without knowing how it was maintained, you’re taking a gamble.
Shoes
Feet come in all shapes, and shoes mold to the original wearer. Picking up a used pair can lead to blisters, poor support, or just an uncomfortable fit. Also, sweat and bacteria can soak into insoles, even if they look clean.
Running shoes are especially risky since cushioning breaks down with use. Foot health matters more than a quick deal, so it’s usually best to buy footwear that’s brand new.
Bathing Suits
Swimwear touches sensitive skin and tends to stretch out with use. Used bathing suits might not offer the same fit or coverage they once did. Hygiene is another issue, because suits can trap bacteria and other stuff that soap alone might not fix. Fabric also weakens over time, especially with exposure to chlorine or saltwater.
Tires
Worn-out tires don’t always show damage right away, but their safety can be compromised. Tread depth, age, and prior use all play a role in how well they perform.
Secondhand sets might save money short-term, but blowouts or poor traction could cost way more in the long run, because it’s impossible to know how they were driven or stored. Getting brand-new tires gives you the best shot at staying safe on the road.
Hairbrushes
Personal grooming tools like hairbrushes seem easy to clean, but that’s not always the case. Bristles can hold onto oils, dead skin, and even lice eggs. Deep cleaning doesn’t always get rid of everything, especially if it’s an older brush. Sharing these kinds of items can spread bacteria or scalp conditions.
Blenders
Kitchen gadgets have lots of small parts, and blenders are no exception. Blades dull with use, seals can leak, and motors might be close to burning out, so a used one could break right after you buy it. Food safety is also a concern, because old food bits can hide in places you can’t reach. Picking up a new blender ensures it works properly and stays clean.
Underwear
Some things just shouldn’t have a history. Intimate items like underwear are just too personal to trust secondhand. No matter how many times they’ve been washed, you really can’t know where they’ve been or what they’ve been through.
Elastic stretches out and fabrics wear thin, while the fit changes over time. Comfort and cleanliness both suffer, so buying new guarantees everything is fresh, snug, and exactly how you want it.
Pillows
Bed pillows soak up sweat, drool, and dead skin cells over time. Dust mites love them, too, so even if a pillow looks fine, it probably isn’t as clean as it seems. Most can’t be washed thoroughly without falling apart, so there’s no real way to sanitize them. For something that’s pressed against your face for hours, it’s worth the small extra cost to get one that’s never been used before.
Laptops
Tech gets outdated fast, and laptops are especially tricky. Batteries wear out, keyboards get sticky, and past issues might be hidden under the surface. That great-looking used model could be on its last legs.
Warranties often don’t transfer, and you might not get updates or support. Buying a new one helps you avoid problems and guarantees you get the latest features without mystery glitches showing up later.
Stuffed Animals
Soft toys seem innocent enough, but they’re magnets for germs. Dust, allergens, and lice can hide inside. Kids chew, drool, and drag them everywhere, which makes hygiene a serious concern. Seams may also be loose or weakened, posing a choking risk. If a toy is meant to comfort a child, it should be clean, intact – and brand new.
Water Bottles
Reusable bottles often hide wear and tear you can’t see. Cracks in plastic, mold in hard-to-clean spots, and lingering smells are all red flags. Even stainless steel ones can carry traces of old drinks or cleaning chemicals, and a used bottle might not seal properly either, which means leaks and spills.
