So i've been using my diana for this cycle, and i just took it out a little bit ago after having it in for 12 hours and *maybe* 15 minutes tops, not even i don't think. Upon removal i noticed a rancid funk and immediately washed it then boiled it. The smell is still there... What do you ladies think my best options are? Is it safe to sun a colored cup without it fading? Please help. Thanks in advance.
