Not all household items will be printed with the manufacturing date or shelf life, and most people probably don’t think that items will be “out of time” like food. However, experts remind that if some things have been used for too long, they are actually invisibly endangering the health of their families. The foreign website Prevention collects suggestions from health experts and lists 15 common household items "life-saving" and should be replaced or abandoned immediately when the life is over.

1. Seaweed

Permanence: 30 days

American microbiologist and professor of environmental science Chuck Gerba warned that water-filled seaweed is a temperature bed for the breeding of cyperidus and samella. The amount of bacteria will reach its peak within three to four days. It is recommended that people heat and disinfect the seaweed, put it in a microwave for about 30 seconds or wash it with a dishwasher.

2. Mop

Life: 2 to 3 months

Chuck Gerba said that if you hear that the mop cloth has a strange smell, you should change as quickly as possible, because this means that bacteria have grown in large quantities, and if you use a contaminated mop to beat the house, it is as if you are spreading bacteria.

3. Life of cutting board: If scratches appear, the scratches on the cutting board are prone to contain pathogenic bacteria. If you want to prolong the life of the cutting board, you can put the plastic cutting board into the dishwasher, or use bleach or food disinfectant to clean the wooden cutting board regularly.

4. Non-stick and flat-bottomed pot life: If there are any debris or scratches on the surface layer, Ryan Sinclair, associate professor of environmental microbiology and public health technician at Romalinda University in California, reminds that the non-stick pot surface layer is PFA fluorocarbon material. If it is broken, it will continue to be used. Carcinogens will enter our bodies through the food. It is recommended to use iron or stainless steel instead.

5. Plastic freshness box

Performance: If there is wear, it should be damaged.

Sinclair said that even if it is a high-grade plastic container, chemical substances will be released after multiple high-temperature heating. If the quality and color of the plastic freshness box changes, such as softening, brittlement, and dyeing, it should be recycled. People can consider using glass or stainless steel containers to avoid doubt.

6. Cleaning agent life: 6 months to 2 years Although it is impossible to imagine that cleaning supplies will be damaged, the cleaning effect will gradually weaken as time goes by. For example, it is best to use it within six months after the bleach is opened, otherwise it will be a waste to use it for disinfection. Other types of cleaning agents and water-soluble cleaning agents are also best used within two years.

7. Pillow

Life: 1 to 3 years, Dr. Michael Breus, a clinical sleep expert, pointed out that the life of pillows depends on the material, and the life of memorable foam pillows has the longest life, while the life of feathers and feather pillows is shorter. When the pillow has become distorted or uneven, continuous use can increase the risk of pain in the neck, shoulders, or upper back. In addition, the pillow is easy to absorb sweat, oil, dandruff and dust in human body. People with allergies and asthma should pay special attention. It is recommended to clean or dry according to the specifications.

8. Bed wall

Life: 7 to 12 years

If you feel muscle stiffness and body aches when you wake up, you may need to consider whether the bed wall has lost its elasticity. The bed should be able to fit our spine so that the muscles can relax during sleep. If you think it's still useful in the long run, you can also try to turn the bed position.

9. Stainless melon bath towel

Life: When the color changes, moldy or has a strange smell, it should be wiped off. Some people will use spoilers and spoilers to scrub the bath, but because the supplies are placed in a damp bathroom, it is very easy to breed bacteria. If the skin is damaged, there will be infection risks. It is recommended to clean it thoroughly after use and dry it. If possible, place it outside the bathroom.

10. Toothbrush

Life: 3 to 4 months

Many people know that toothbrushes need to be replaced, but they often forget the time as soon as they are put. It is best to change the toothbrush in 3 months, but if you see that the bristles have been worn, you should throw them away. Otherwise, the cleaning function of the toothbrush will not be able to be exposed, which may increase the risk of plaque and tooth decay.

11. No-wash scraper

Use life: 3 times

The scraper scrambler is designed as a one-time, but many people think that it is not allowed to be used once, so they are reused. However, the blades of scraper supplies are rougher and will soon become corrosive and bulbous. If used continuously, it is easy to cause skin allergies or infections.

12. Moisturizing cream

Life: 1 year

Some people are accustomed to buying a large can of moisturizing products to use slowly, but the moisturizing cream will lose moisture over time, and using your fingers to touch the inside of the can for a long time may also cause pollution. It is recommended to use the nursing products as quickly as possible after they are opened, and do not think that it is a waste of money to lose the products that have been left for too long.

13. Bathing

Performance: When mold or mildew appears on the inner leaf, it will be replaced

Can you imagine that you suck the mold in the air into your body while taking a bath? Especially for families with sensitive respiratory tract, asthma, and low immune function, pay special attention. It is recommended to use bleach to disinfect windows, or to change them regularly.

14. Smoke alarm

Life: 10 years

Most residential alarms use longer battery life. In order to avoid product disparity affecting the function of the alarm, it is recommended to change it once in 10 years. Some new alarms will have battery warnings. When you hear a "slow" short sound, it means that the power is about to be insufficient.

15. Carbon monoxide detector life: 5 to 10 years

The recommended replacement years in the instructions for detectors of different brands may vary. Some will remind users to change the battery through warning sounds, but it is recommended that the public still remember the manufacturing date and make changes according to the product label to avoid becoming a home safety hazard.
