How to Clean Underwear Properly?

Most people just throw the underwear in the washing machine with some detergent. But this is not going to get rid of bacteria and fecal matter that the underwear carries.

After you wash your underwear in the machine, you need to clean the washing machine. The germs that are washed away from the underwear cling to the washing machine.
