also, i live in a dorm, so there isn't a place that i can boil water for my cup. ive been cleaning it with rubbing alcohol until i noticed recently that the divacup website advises to not clean with rubbing alcohol (then again, it also says not to clean with hydrogen peroxide, and i know many people do that). would soaking in hydrogen peroxide and/or alcohol be enough to clean it after each cycle (especially now since it's been through the wash and a BV infection), or should i be worried that there's nowhere i can boil it? is there a difference between cleaning with hydrogen peroxide and alcohol? aaand what type of hydrogen peroxide should i be using?
