Cleaning your MeLuna
1. Wet the cup under running water (30-40°C) for 5 seconds.
2. Use a minimum of 1/4 tsp of Cetaphil to rub the cup for a minimum of 30 seconds. Use the MeLuna brush to clean the two air holes (run the brush through each air hole at least once).
3. Rinse the cup under running tap water (30-40°C) for a minimum of 30 seconds.
Dry the cup completely before storage. The MeLuna menstrual cup should never be stored in an airtight container. This could promote odors. We recommend that you store your MeLuna menstrual cup in its bag (each MeLuna menstrual cup comes with its own storage bag).
Disinfecting your MeLuna
Your MeLuna should be disinfected before your first time using it and after every period. You may disinfect it by floating it completely submerged for 3-5 minutes in boiling water (100° Celsius/ 212° Fahrenheit). Take care when removing the cup as the water will be very hot.
Always wash your hands before handling and inserting the MeLuna. With adequate cleaning and disinfection procedures it is actually much more likely that bacteria and contaminants are introduced via your hands than the cup.

General information on cleaning and maintaining your MeLuna
What can damage the MeLuna?
Wrong detergent: Use only mild soap or detergent - no harsh abrasives.
Incorrect storage: One thing that can harm the material of the MeLuna and result in a cup becoming prematurely porous are UV rays. Under normal storage there is nothing to fear. MeLuna should not be left out in the sun. Also high temperatures above 140 ° C should be avoided.
Recommendations for cleaning on the go
Wipe out your cup with some paper or a skin-compatible cleaning cloth and re-insert it. Also cleaning with clear, cold water is possible.
Bringing along cleaning wipes or a bottle of water can be very helpful in public toilets, since you do not have a sink within reach.
Disinfection by boiling water
in the saucepan:
Bring enough water to boil in a small saucepan. Simply place the cup for 3 minutes in the boiling water. Make sure that they have enough water in the container so that the cup floats in it.
In the microwave: Of course, the cup also be disinfected with the microwave. As always they must also be heated in sufficient water, otherwise the disinfection effect not occur. The TPE plastic used for the MeLuna is nonpolar and does not heat up in the microwave. Disinfection is carried out by the heated water. Be careful not to burn yourself when you remove it. The water will be very hot.
BE CAREFUL: In order for your cup to not melt, do not leave it lying on the bottom of the pot without water! Do not leave the pot unattended. For safety, the use of a timer may be helpful. Cooking times of 3 minutes are sufficient.
TIP: It works great if you put the cup inside of a whisk. The whisk (or strainer) keeps the cup safe from melting and you can retrieve it without burning your fingers.
Hot salt water:
You can also add a little salt. This helps to prevent discoloration and increases the cleaning effect.
Adding a little bit of vinegar in the boiling water prevents lime scale and has a natural disinfectaning and deodorizing effect. Vinegar water can be used hot or cold at not more than a 3% concentration.
TIP: Some disinfecting tablets like those made by Milton for baby and breastfeeding items are also sometimes used.
TIPS for special cleaning problems
To prevent odors always COLD rinse the cup after removal. The smell is caused by protein compounds in the blood. Unpleasant odors usually disappear when you put your well cleaned cup for a few days in a dry, well ventilated place.
Staining of menstrual cups can be lessened when you treat with vinegar or salt water. Hard to reach places can be reached very well with an interdental brush, to prevent and remedy deposits.
Odor or discoloration of your MeLuna
Slight discoloration may develop over a long period of use and may occur in any menstrual cup brand. With regular thorough cleaning this staining can usually be limited.
Odor formation can be prevented by not wearing the cup for too long periods of time. The maximum time span to wear the cup should not exceed 8 hours to 12 hours in the body. Because of the variations of proteins in the blood it is possible that a menstrual cup suddenly takes on a strange smell, even though it has been cleaned as usual.
