Treasure hunting at a thrift store is not without its pitfalls. From the advice of wary consumers and safety experts urging caution about what you bring home, discover which items are best left on the shelf.
Helmets

Buying a helmet secondhand might seem like a good way to save money, but it’s a risk that is not worth taking. Helmets are designed to protect you from a single impact. Once they’ve absorbed that shock, their protective capabilities diminish significantly. You’ll never be able to tell just by looking if a secondhand helmet has been compromised, so it’s always best to buy new.
Car Seats

Car seats are crucial for keeping your little ones safe on the road, and their history is not always transparent in a secondhand purchase. Even minor accidents can cause invisible damage to a car seat, rendering it less effective in protecting your child. Manufacturers also frequently update safety features, meaning a secondhand seat may be outdated.
Mattresses

Secondhand mattresses may come with hidden guests like bedbugs, dust mites, and other allergens. Over time, mattresses also collect sweat, oils, and skin cells, making them unsanitary. The wear and tear on a used mattress can affect its support, leading to uncomfortable nights and potential back problems. Investing in a new mattress ensures cleanliness and comfort.
Shoes

Shoes mold to the feet of their first owner, which means a secondhand pair might not fit you correctly, leading to discomfort and foot problems. Worn-out soles and support structures can also affect your posture and gait. The risk of fungal infections, like athlete’s foot, increases with used footwear. It’s healthier for your feet to choose new shoes tailored to your fit.
Makeup

Used makeup carries a high risk of contamination from bacteria and viruses, leading to skin irritations or infections. The consistency and color of makeup products can change over time, affecting their performance and appearance on your skin. Moreover, cosmetic products have expiration dates, and secondhand items may already be past their prime. For the sake of your skin’s health, opt for fresh beauty products.
Swimwear

Swimwear is intimately personal and should be bought new for hygiene reasons. The fabric in used swimwear may stretch or wear out, offering less support and coverage. Chlorine and saltwater degrade swimwear over time, compromising its durability and appearance. To ensure the best fit, quality, and hygiene, new swimwear is always recommended.
Underwear

The thought of wearing someone else’s underwear can be unsettling due to the personal nature of these garments. Underwear is prone to wear and tear and may not hold its shape, leading to discomfort. The fabric can also harbor bacteria and fungi, posing a risk to your health. For hygiene and comfort, it’s best to buy new underwear.
Water Filters

Water filters are designed to ensure the purity and safety of your drinking water. Over time, filters can accumulate harmful bacteria and mold, and their filtering capabilities degrade. Secondhand filters may not perform effectively, putting your health at risk. For guaranteed water safety, investing in a new water filter is essential.
Vacuum Cleaners

Secondhand vacuum cleaners may seem like a bargain, but they often come with hidden problems. Previous use can lead to clogged filters and worn-out motors, reducing their efficiency. Dust and allergens trapped inside the machine can be released back into your home. For reliable performance and cleanliness, a new vacuum cleaner is a wise choice.
Laptops

Secondhand laptops might carry outdated software, potential malware, and diminished battery life. Wear and tear on components can lead to unexpected failures and data loss. Manufacturers’ warranties rarely transfer to second owners, leaving you uncovered in case of defects. For the latest technology and reliability, new is the smarter choice.
Baby Cribs

Cribs are essential for your baby’s safe sleep, but secondhand cribs may not meet current safety standards. Recalls and safety notices are common in older models, and missing hardware can pose serious risks. Wear and tear might not be immediately visible but can weaken the structure. Ensure your baby’s safety with a new, up-to-code crib.
Cookware

Secondhand cookware may have scratches and wear that compromise its non-stick surface, leading to uneven cooking and potential health risks from flaking materials. Over time, cookware can warp, affecting its heat distribution. Previous use might also leave behind residues that are difficult to completely remove. For optimal cooking performance and safety, new cookware is recommended.
Electrical Appliances

The condition of secondhand electrical appliances can be difficult to assess, and they may not meet current safety standards. Faulty wiring and worn-out components can pose a fire hazard or risk of electric shock. Efficiency may also be compromised, leading to higher energy consumption. For safety and efficiency, opt for new electrical appliances.
Perfumes

Perfumes and colognes degrade over time, with exposure to light and air altering their scent and effectiveness. Secondhand bottles may have been opened and exposed, accelerating this degradation. The original scent may no longer be true to its intended fragrance. For the best fragrance experience, a new bottle is the best choice.
Pillows

Over time, pillows accumulate dust mites, dead skin cells, and body oils, making them a hotspot for allergens. The structure and support of pillows degrade with use, affecting your sleep quality and potentially causing neck pain. Secondhand pillows cannot guarantee the cleanliness or the support you need. For a good night’s sleep, invest in new pillows.
Pet Supplies

Secondhand pet supplies, like beds and toys, can harbor bacteria, pests, and odors from previous pets. Wear and tear can also compromise the safety and comfort of these items, potentially putting your pet at risk. Materials may break down, creating choking hazards for pets. For your pet’s health and happiness, new supplies are the best option.
Wetsuits

Wetsuits are designed to fit snugly and provide thermal protection while in water. Over time, the material can stretch and lose its insulating properties, reducing its effectiveness. Secondhand wetsuits may also have small tears or worn areas that allow water to seep in, further diminishing their performance. For the best fit and insulation, a new wetsuit is essential.
Personal Hygiene Devices

Items like electric toothbrushes and razors are personal hygiene devices that should not be shared or bought used. These items can retain microscopic particles from previous users, posing a risk of infection. Wear and tear on the device can also affect its performance, leading to ineffective cleaning or shaving. For personal hygiene, it’s safest to buy these items new.
Fitness Equipment

Secondhand fitness equipment may have internal wear that isn’t visible, affecting its safety and functionality. Over time, cables can fray, bolts can loosen, and padding can wear down, all of which can lead to injury. Previous use might also mean the equipment is not calibrated to your needs. For safety and effectiveness, opt for new fitness equipment.
Tires

Tires are critical for vehicle safety, and their condition can significantly affect your driving experience. Secondhand tires may have uneven wear, hidden damage, or be close to the end of their useful life. The rubber compounds in tires degrade over time, reducing their grip and increasing the risk of failure. For the utmost safety on the road, new tires are recommended.
Smartphones

Secondhand smartphones may come with a host of issues, including battery degradation, outdated software, and potential security vulnerabilities. Previous owners’ data might not be entirely erased, posing a privacy concern. Wear and tear on the device can lead to functional issues like a malfunctioning camera or unresponsive buttons. For reliability and security, a new smartphone is the smarter choice.
