Wet soap cures position bitted by mosquito.

It is inevitable bitted by mosquito in summer. Though there are many kinds of toilet water in the market, but we cure the mosquito bite with soap. It will not itch soon after put the wet soap on the position bitted by mosquito.

Save electricity when cook rice.

Electric cooker is used by almost every family. If you cover a towel on the cover (do not block up the air hole), the rice cooker faster than non-cover their towels. I have been cooking rice like this. You can try this method. The operation does not trouble, but can save electricity.

Paste toothpaste to cure athlete's foot.

My toes always suffer from athlete's foot and foot blisters, and ulcerated to itch in summer before every year. Later, I heard that toothpaste can prevent athlete's foot. So I decide to try. I wipe a little toothpaste on my soles of the foot and toe after washing foot every day. It is cooling and itching. Now the athlete's foot has never occurred.

Prevent from ant.

There are many ants in my old house in summer every year. Almost there is no any method to prevent from ants. When I have a dinner, these ants often climb up the table. These ants climb into the leftovers too. Later, a friend introduced me a method that wrapped the legs with aluminum foil. Because the aluminum foil is very smooth, these ants almost could not climb up the table.

Electric fan defrost.

There is a layer of thick frost in the inner of the refrigerator always in summer. It is very trouble to clean frost in refrigerator. It needs to wait for a long time until the frost melt. Open electric fan aimed to the Freezing Chamber until the frost melt. Now the frost is cleaned easily.

Scalding infection caused by soy

In daily life, we often encounter unexpected burned situations, such as boiling water, hot oil, hydrothermal scalding, or hot pan and other contacted scalding. Many people first think that what to use to smear in the affected area, such as red syrup, toothpaste, and soy sauce, etc. They think that it will not only reduce pain, but also diminish inflammation. In fact, this method is not desirable.

Toothpaste, soy sauce deposited in the wound is not salubrity in itself. It is also conducive a growth of bacterial. While others which are not symptomatic ointments to the wound will play a side effect. But make the wound more susceptible to infection. Infection will affect the burn diagnosis of doctor and make patient suffer pain in the cleaning process.

In addition, it is need pay attentions that do not pierce the blisters after cleaning. Because broken skin may cause infection.

Toothpaste and health

Toothpaste is often used to clean oral cavity with the material. But it has some questions we need to notice. If we do not pay attention these questions, it will affect our health. The research show that toothpaste contains many chemical substances, such as foaming agents, friction agents, adhesives, and perfume, antiseptic anti-bacterial drugs, these materials would make a chemical reaction after a long time. It will cause not only the deterioration, but also reduces ability of the decontamination and cleaning. In general, shelf life of toothpaste is about 10 months. If shelf life of toothpaste exceed this period, it is highly perishable. The allergic reactions will caused that people use toothpaste which is metamorphism.

In addition, lead ions will enter the toothpaste, if the store of toothpaste which is lead quality is too long. If toothpaste which is lead quality is used for long time, chronic lead poisoning may occur, and results in decline of nerve conduction, stagnation of mental development, recession of understanding.

Therefore, it should be noted the production date. It is not used, if shelf life of toothpaste exceeds 10 months.
