Everyone knows that foods have a shelf life, and maybe they also know that there are shelf life for daily chemicals. But what you may not know is that many daily necessities also have a shelf life. If you don’t replace it in time, but let them work overtime, the accumulated bacteria will slowly invade our body, or it may cause illness.

Chopsticks

Even after washing it cleanly, pathogenic microorganisms such as E. coli, Staphylococcus aureus, and Streptococcus can be seen under a microscope after using wooden or bamboo chopsticks for more than half a year. After being used for more than 1 year, bamboo and wooden chopsticks will generally show discoloration and peeling, which can no longer be thoroughly cleaned.

It is recommended to replace bamboo and wood chopsticks every six months, or use metal chopsticks that are easy to clean.

Toothbrush

According to oral hygiene requirements, the best time to use a toothbrush is no more than 3 months. Perhaps the appearance of the toothbrush has not been damaged for 3 months, but a certain amount of bacteria has been hidden in the bristles, which is not good for oral health care.

If you are used to brushing your toothbrush carefully and for a long time, the toothbrush will inevitably wear faster than the average person. It is recommended to reduce the time for toothbrush replacement.

Towel

Towels are easy to accumulate bacteria. Of course, we should pay attention to the cleaning and disinfection of towels in our lives. However, cleaning, drying, and high-temperature cooking can only control the number of bacteria in a short time, and cannot permanently remove bacteria.

It is recommended to replace it every 3 months or so, instead of waiting for damage.

Bath ball

Compared to towels, dead skin and dirt on the bath balls are more likely to breed bacteria. In addition to thorough cleaning and disinfection every week, it is also recommended to replace with a new one every quarter.

Dishcloth

Includes traditional dishwashing cotton and scouring pads. Within 20% are hidden bacteria such as Escherichia coli and Salmonella that are enough to cause disease. Especially in summer, some dishwashing cloths that are not clean enough will breed a lot of bacteria, so that the tableware will be cross-infected due to contact with the dishwashing cloth during the washing process. It is recommended to replace it once a month.
