A menstrual disc is a flexible, reusable device, typically made of medical-grade silicone or TPE, that is inserted into the vaginal fornix to collect menstrual fluid. Unlike a menstrual cup, the disc rests high up at the base of the cervix and is held in place by the pubic bone, not by suction. Because it is designed to be reused for multiple cycles over several years, maintaining rigorous hygiene is paramount for user health and product longevity. Proper sanitation prevents the buildup of bacteria and the degradation of the material, ensuring the disc remains safe and effective for its intended lifespan.
Routine Cleaning During Wear
Cleaning the disc every time it is removed (up to every 12 hours) is routine maintenance, distinct from deep sanitization. This process focuses on removing menstrual fluid and surface contaminants before reinsertion. Begin by rinsing the disc thoroughly with cold water immediately after emptying its contents, as cold water prevents blood pigments from staining the material.
After the initial cold rinse, wash the disc using warm water and a mild, pH-neutral, oil-free cleanser. While specialized washes are available, a gentle, unscented soap is also effective. Ensure all soap residue is completely rinsed off with warm water before reinsertion, as residue can irritate the vaginal environment and compromise the material over time.
End-of-Cycle Deep Sanitization
Deep sanitization is required before the first use and at the end of every menstrual cycle to eliminate microorganisms that routine washing may not remove. The most common and effective method is boiling the disc in water, which uses high heat to reduce microorganisms to a safe level.
To boil the disc, use a dedicated pot not used for food preparation and fill it with enough water to fully submerge the disc. Once the water reaches a rolling boil, place the disc into the pot. Ensure the disc does not rest directly on the bottom or sides, which can cause scorching; using tongs or a whisk to suspend it prevents this damage. The disc should be boiled for a minimum of five minutes, and no more than ten minutes, for adequate sanitization.
Alternatively, dedicated electric or microwave steam sterilizers designed for menstrual products offer a convenient, controlled heat source. These devices use steam to reach high temperatures and typically complete a cycle in under six minutes. Users may also opt for sterilization tablets formulated for menstrual hygiene products, which are dissolved in water to soak the disc. After any deep sanitization method, remove the disc carefully with clean tongs, rinse it with water, and allow it to cool completely.
Safety Guidelines and Storage
The material integrity of the menstrual disc (silicone or TPE) is directly affected by the cleaning agents used. Harsh chemicals break down the polymer chains, leading to a compromised surface susceptible to bacterial colonization and tearing. To protect the product and your health, avoid using substances like bleach, hydrogen peroxide, rubbing alcohol, or antibacterial hand soaps.
Avoid scented or oil-based soaps and cleansers containing glycerin, as they leave a residue that degrades the material and may disrupt the vaginal pH balance. Only mild, pH-balanced, fragrance-free, and oil-free cleansers are safe for routine use.
The disc should be replaced if you notice a persistent, strong odor after sanitization, or if the material shows signs of damage such as tears, stickiness, or an irreversible, chalky residue.
For storage between cycles, the disc must be completely dry to prevent microbial growth. It should be stored in a breathable container, such as the manufacturer’s cotton pouch, and kept in a cool, dry place away from direct sunlight. Storing the disc in an airtight plastic container is not recommended, as it traps moisture and encourages bacterial growth.
