1. Underwear needs to be changed and washed every day

　　Don't leave underwear overnight, or a large number of bacteria will grow, making it difficult to wash.

　　2. Underwear needs to be washed by hand

　　It is best to wash the underwear by hand, or wash it alone, try not to wash it with pants and socks. One is that the washing machine is not clean, which may lead to the spread of germs; the other is that hand washing can increase the friction density, which is conducive to local cleaning, so that the underwear can be washed more cleanly.

　　3. What to use to clean underwear

　　As we all know, women's private parts are in a weakly acidic environment, and cleaning products are generally alkaline, so we should choose cleaning agents that are not too alkaline and have better cleaning capabilities, such as soap, or soap with sterilization and disinfection capabilities.

　　At the same time, it is best to prepare a special cleaning utensil. In addition, many girls often use too much detergent in order to wash their intimate clothes, which will cause residue and cause skin allergies.

　　4. Disinfect under the sun

　　In order to maintain the image of a lady, many girls always hang their panties in a dark place. This will live up to the good intentions of nature, because sunlight contains ultraviolet rays, which can sterilize and disinfect, and keep the panties hygienic.

　　If you are still embarrassed to let the shorts bask in the sun, use a dryer to dry the shorts thoroughly. Clean and refreshing panties are comfortable to wear.
