How to wash socks?

Tips for washing socks are as follows:

1. Soak socks in clean water for half an hour, so that stains in socks can be fully dissolved in water.

2. Put the socks on the washboard, wash them with soap, rub them back and forth on the washboard, and rub out rich foam, so that the stains can dissolve into the foam.

3. When all the stains are cleaned, then pour out the dirty water and wash it twice with clear water, and the socks will be clean.

4. Gently wring out the washed socks, and then hang them in a cool and ventilated place to dry.
