The Secret of the Shelf Life of Common Items

①The service life of the rag is 2 weeks

Kitchen sponges contain tens of thousands of bacteria and must be replaced every one or two weeks. After each use, it should be thoroughly washed with hot water, dried in the sun, and disinfected in the microwave once every other day.

②The service life of the toothbrush is 3 months

The total working time of each toothbrush should not exceed 6 hours. If you brush your teeth twice a day for two minutes each time, the life of a toothbrush is about three months. People who brush their teeth three times a day should change their toothbrushes once a month. People with oral diseases such as gingivitis should change their toothbrushes every three weeks. If you can't remember how long you have used your toothbrush, you can judge by the regularity of the bristles. If you have a cold or other infectious disease, you should get a new toothbrush after you recover.

③The service life of bra is up to 6 months

Machine washing and tumble drying will cause the fabric of your bra to age faster, so wash by hand on a regular basis. But even so, if you wear it two or three days a week, the lifespan of an ordinary bra is 3-6 months. If your bra starts to lose its shape and the straps start to loosen, it's time to change it.

④The lifespan of the pillow is 1-2 years

Experts point out that pillows are places where dirt and grime easily hide. If they are not cleaned for a long time, they can easily breed mold and mites, and may also cause allergies, asthma and other respiratory diseases. The best way to solve this problem is to replace it every two years.

In addition, if you encounter pillowcase discoloration (caused by sweat or fungus), neck pain after waking up (pillow deformation or pillow filling clumps), or often feel breathless when you wake up in the morning (dust in the pillow causes allergic reaction), you should replace the pillow immediately.

⑤The service life of sports shoes is 8-12 months

Sports medicine experts say that you should replace a pair of sneakers every 1,000 kilometers. So, based on people's average amount of exercise, the service life of a pair of sports shoes is 8-12 months. Once the service life is exceeded, the protection and shock absorption effect of the shoes on the feet and torso will be greatly reduced. To protect your knees and back, you should replace your sports shoes regularly every year.

⑥ The edges and corners of kitchen and bathroom sanitary ware turn black and moldy in less than half a year

It is common for glass glue to become moldy and black. This is because glass glue itself is suitable for organic matter. The glass glue in the bathroom is damp due to water, and many microorganisms such as mold will grow on the surface and gaps of the glass glue. Over time, the mold will cover the surface of the glass glue and turn black. At the same time, the mold will absorb more dirt and bacteria, making the edges of the bathtub and corners look dirty and disgusting, which not only affects the appearance, but also spreads various infectious diseases and endangers the health of you and your family.
