Basic practices regarding hygiene of the menstrual cup to avoid catching an infection or damage your menstrual cup

  • Before handling the menstrual cup wash your hands with normal soap.
  • On the first ever use of the menstrual cup, sanitize your menstrual cup. See in this post the various ways to do it.
  • You need to sterilize your cup only once per cycle, at the end or at the beginning. While you are having your period you can simply rinse your cup with water and mild soap when available.
  • After its last use of your period, wash your menstrual cup carefully and store it in its own pouch or box provided with your cup.
  • It is recommended to rinse the cup with cold water at first when it has just been removed. The use of cold water help prevent staining and odor. Then you can use hot water with a neutral soap.
  • Long fingernails should be thoroughly brushed. Beneath them is accumulated organic material also including bacteria and fungi. If the nails are not properly washed, you may introduce them into the vagina. Same thing goes for using tampons without applicators.
  • The tiny suction holes that are near the rim of most menstrual cups needs to be kept clean. Use cleaning brushes to to do so.  Another easy technique: Fill the cup with water, place your palm on it, turn upside down and squeeze! When the water squirts out through the air-holes, they should be instantly cleaned!

Most of the bacteria and pathogenic viruses for humans are already inactivated at temperatures of 65 ° C. For this reason the boiling is a safe method, since the temperature of 100 ° C are denatured proteins of cell membranes and the cells are destroyed.

It is NOT absolutely necessary to boil the menstrual cup between an insert and the other. Tap water is safe to wash it. Only some special occasions (eg. no access to clean water in foreign countries) may require the use of natural bottled water.

According to the manufacturer’s indications the menstrual cup is boiling over medium heat for 5 minutes in a pan (careful not to forget it on the fire, because if the water evaporates the cup burns).

Here is a little tip, put your cup in a cooking whisk that was it will keep it from being in direct contact with the pan.
