Underwear should be cooled with hot water.
Underwear needs hand washing. Usually, if the weather is too hot, wash it with cold water, and if it is too cold, wash it with hot water. After all, this temperature is the most suitable for us, but it is not necessarily suitable for washing underwear. If the cleaning is not in place, it will also have a great impact on the body. Of course, some people have their own opinions on whether to wash underwear with hot water or cold water.
Usually we talk about high temperature disinfection. After all, many people have an illusion that the temperature of hot water can kill bacteria in high temperature environment. Actually, this is not the case, but it will also destroy the fibers of clothes. In fact, it is best to wash underwear with cold water, so that it can clean underwear to a greater extent, and there will be no dirt to leave other colors.
There must be substances secreted by the human body on the underwear. After all, even if you wear clothes, there is sweat secretion. The hardest thing to clean is that when a woman comes to her period, there will always be a little blood on her body. These secreted substances all contain protein, because they solidify quickly and it is difficult to clean them with hot water. So it is usually washed with cold water first. If there is blood on it, it's best to apply a clear lotion to dry underwear, and then wash it with cold water after dry wiping, so cleaning will be more effective. In this way, underwear will be softer, and underwear that is not thoroughly cleaned for a long time will become very hard.
Usually it is best to wash underwear with cold water and then dry it in the sun, which can also play a role in sterilization. Although cleaning underwear is a small matter, it still has a lot to do with the health of family members. However, it should be noted that even if the underwear is washed very clean, it usually needs to be replaced after 3 months.
