I never leave the cup in for more than 12 hours, and the Lunette soap I use gets rid of any discoloration or scent (even though there usually never is any).
Do you all empty every 8? I just want to make sure that I'm not keeping old blood inside for too long, or getting bacteria or anything...
Thanks in advance!!
(I tried to check the memories for an exact answer, but didn't find one. If anyone knows of a link that discusses it I love to be directed there!)
