Basically during ur period you just rinse it after you empty it. And then when you’re off your period, boil it for like 10 minutes to sterilize. Super simple and relatively painless! The risk of TSS and infection is super low (I think due to the silicone? Idk). The disposable ones also are low-risk, but knowing I’m not going to literally die if i cant rinse it out (public bathroom moment) is super comforting lol
