What is the use of adding salt to washing clothes?

Salt has the effect of fixing colors, so soaking clothes in salt water can prevent them from fading. The effect is more obvious on black or red clothes.

method:

When washing clothes that fade easily, first soak the clothes in salt water for about 30 minutes, rinse them with clean water, and then wash them in the usual way.

If the new clothes you bought are easy to fade, soak them in salt water for half an hour before washing them for the first time. The purpose is to fix the color, so that the clothes will not fade easily.

The function of salt is to fix color. If the clothes do not fade, there is no need to add salt to the clothes.

Won't! It can also kill bacteria, but the effect is not very strong. If you want to sterilize, the concentration of table salt should be at least 5%, otherwise it will have almost no effect. Table salt has a certain corrosive effect on some metal components, but using it in a washing machine should not be a big problem, because the washing machine itself is often in contact with detergent (the ingredients of detergent are mostly salts such as sodium polyalkylbenzene sulfonate and sodium silicate), so corrosion resistance must have been considered when designing the washing machine, so you should be able to use it with confidence. However, according to the 5% salt concentration, 1 kg of salt is needed for 20L of water, so it is recommended that you use other disinfectants.

In addition, the residues on clothes are generally non-vegetative bodies in the non-growing stage, such as mold spores and bacterial spores, and salt water has almost no killing effect on them. If disinfection is really necessary, it is recommended to use disinfectants with strong disinfection capabilities such as 84 disinfectant and benzalkonium bromide. If you do not consider the cost and need absolute safety, you might as well try using "contact lens cleaning solution" to add it to the laundry water, which is very effective.
