Title: Hard to clean
Review: This looked like a great design, but after a few days of use I noticed an alcoholic smell. There was black gunk where the lid screws in, hard to reach. Soaked it in bleach and that was OK, but after using it more, and trying to clean inside the lid under that contraption, I decided to try soaking it in vinegar. After a day, I still noticed some gunk in the lid. So I took it to a WaterPik.And there was a LOT of black gunk coming out of that lid.I appreciate all the cleaning tips, but even with a WaterPik I'm not sure I'm getting all of it, since I can't see under that lid thingy. I'm looking to return this.On the plus side, it's pretty leakproof.
