I have a fantastic opportunity to take an indefinite trip traveling through Central and South America in just a few weeks. I'm really excited about it! I also really love my large Fleurcup and plan to take it with me. What I'm concerned about, however, is changing and rinsing it (and keeping my hands clean while doing so) in areas where the water is not safe to drink (which will likely be most places I am staying). It seems to me that this would pose a threat of infection, would it not? I'm guessing I will have to utilize my bottled drinking water for cleaning my cup, but I'd prefer to reserve that for drinking if possible, because I just know I'll waste a ton of it before I get a system down. Does anyone have any tips or tricks they could share with me for cup use in third-world countries?
