Tableware: Replace every 5-7 months. Long-used tableware accumulates bacteria and cleaning residue, significantly increasing the risk of illness. Doctors recommend replacing tableware at least every six months, in addition to regular disinfection. Bath sponges: Replace every 3 months. Prolonged use allows bath sponges to collect dead skin and harbor bacteria. Thoroughly clean them every 1-2 weeks and replace them quarterly.
Toothbrushes: Replace every 3-4 months. Rinse toothbrushes thoroughly after use and store upright to dry. Replace immediately if bristles show wear. Each toothbrush should not exceed 6 total hours of use. Based on brushing twice daily for two minutes each time, a toothbrush lasts about 3 months. Replace within 3 months to prevent bacterial buildup.
Towels: Replace every 2–4 months. As fibrous textiles, towels harbor bacteria deep within their fibers that are difficult to eliminate over time. Washing, air-drying, or high-temperature sterilization only temporarily controls bacterial counts without permanent removal. Worn towels become dirty and stiff, turning into new sources of contamination that severely impact skin health and comfort.Therefore, replace towels with new ones every three months or so—don't wait until they're worn out.
Plastic lunch boxes: Discard immediately upon damage. Scratches in plastic containers easily harbor bacteria. Hand-washing is recommended. If you notice cracks, discoloration, or brittleness, dispose of them immediately or switch to glass containers.
Sponge cloths: Replace every 30 days. Sponges readily trap bacteria.Thoroughly clean sponges weekly, rinsing them with hot water after each use and drying them in sunlight. Microwave them for disinfection every other day.Mattresses also accumulate stains that cannot be thoroughly cleaned, meaning we sleep alongside bacteria. It's best to replace mattresses every 5 years, especially for those with poor sleep quality. Contact lens solution: Replace every 3 months. Once opened, solution caps allow bacteria to easily contaminate the solution, increasing the risk of eye infections. Additionally, contact lens cases should also be replaced every 3 months.
Vitamin supplements: Replace those stored for over 2 years. To maintain their efficacy, vitamins should be stored in a cool, dry place and consumed within 2 years. Therefore, if you have such supplements at home, it's best not to take them anymore, even if they haven't expired.
Bras: The average lifespan of a bra is about 6 months. However, women with fuller busts should replace their bras every 3-4 months. Otherwise, the fabric loses elasticity and fails to provide proper support and protection for the breasts.After exercise, air-dry your sports bra before reuse and wash it after every third wear. Machine washing and tumble drying accelerate the aging of the Lycra fabric used in bras. Hand washing with gentle rubbing is the best method for cleaning bras.Replace athletic shoes every 1,000 kilometers walked. Based on activity levels, the lifespan of a pair of athletic shoes is 8-12 months. Once past their usable period, the shoes' protective and shock-absorbing effects for the feet and torso are significantly reduced. To protect your knees and back, you should replace athletic shoes regularly each year.Mascara is the biggest bacterial hotspot in your makeup bag. Experts recommend replacing it every 3 months. Prolonged use of the same tube not only diminishes makeup effectiveness but also risks eye infections from bacteria accumulating on the wand. Additionally, some items don't need frequent replacement but require careful handling.
Headphones: Disinfect weekly with alcohol.Experts advise disinfecting dirty earbuds with alcohol and storing them away from dust.
Metal nail files: Store properly after use. Nail files can spread bacteria; disinfect them with alcohol before each use.
Pillowcases: Wash weekly. Pillows easily accumulate sweat, saliva, dandruff, and dust mites, so change them regularly.
Shopping bags: Wash immediately after use. Shopping bags can spread fecal matter and bacteria from raw meat and vegetables. Washing promptly removes over 99.9% of bacteria.
