After the food has passed the shelf life, we will throw it away. However, many people do not know that many household items also have a "shelf life" and should be cleaned or replaced regularly.
1. Plastic storage box: 3 months. Plastic storage boxes for storing leftovers, mostly containing bisphenol A and phthalate, may be harmful to health for long-term use.
2. Pillow: 2 to 3 years. Usually the pillow is easily deformed in two or three years, and the pillow core is easy to form a mass.
3. Shaver blades: once a week. When the razor blade is used for a long time, it will become dull. Not only will the shaving effect be worse, but it will also breed bacteria and cause skin infection.
4. Cutting board: 1 year. If there are stains or cracks that are difficult to wash off on the cutting board, they should be replaced immediately. Even if it is intact, it is best to replace it every year.

6. Toothbrush: 3 months. Excessive use of the toothbrush not only damages the gums, but also accumulates a large amount of bacteria in the gums, increasing the chance of infection.
7. Bath towel: 2 months. Every time you use the bath towel, it should be placed in a dry and ventilated place. It is best to heat it in a microwave oven for 30 to 60 seconds on medium heat and replace it at least every two months.
8. Comb: 4 years. There is 50,000 germs in a hair follicle on the hair. The gap between the combs is also prone to dandruff and dirt. It is recommended to clean every week and change every 4 years.
