I travel fairly often so I find myself at hotels with no easy way to properly sanitize a rinse bottle. Assuming I could even get my hands on distilled water, and even if the room had a microwave, I'm not sure I could adequately clean and sanitize without access to running water. So far I have just done without rinsing on my trips, which I don't like doing because after just a couple days I am already uncomfortable. Does anyone have any tips, or any ideas for temporary alternatives to rinsing?
