Cleaning method:
1, underwear should be changed every day. Don't let underwear stay overnight, otherwise it will breed a lot of bacteria, which will make cleaning difficult;
2. Underwear needs hand washing. First, the washing machine is not clean, which may lead to the spread of germs; Second, hand washing can increase the friction density, which is beneficial to local cleaning and make underwear wash more cleanly;
3, underwear should choose a cleaner that is not too alkaline and has good cleaning ability, because women's private parts are in a weak acid environment;
4. Use special cleaning appliances to clean underwear;
5, underwear needs to be dried in a ventilated place first, and then don't live up to the kindness of the sun. Ultraviolet rays in the sun can sterilize and keep underwear hygienic. I'm really embarrassed to let my underwear bask in the sun, so I have to dry it thoroughly with a dryer.
