Ut oh, an update to my earlier raving:
The plastic inside parts of the tops absorb scents/flavors and so far I’m having a hard time getting the last out. I’d hope/assumed they were made of plastic that was as limited as possible in this, but it was actually quite easy. I have made two fruited/scented teas in it and each time I had to scrub and soak the lids to get the neutrality back.
The first one wasn’t an intensely flavored tea so a day of scrub and soak practice got it back to normal.
This second one is the admittedly one with a very strong cinnamon component. They’ve been soaked and scrubbed a few times today and are currently soaking again.
100% neutrality isn’t necessary in such things, but these were both strong enough that I’d be smelling them while sipping something else out of the bottle so I need/ed to get them out or at least gone to just a trace.
Will update on success.
Otherwise, though, still an awesome product that I highly recommend. Just be more careful than I in using flavored and scented teas in it.
