I love, love, love this kettle! I held out for the longest time, thinking my newfound love of tea was just a fad… but it wasn’t and I finally bit the bullet. It is especially nice if you sip white or green teas as you select the desired temperature. I have nothing bad to say about it.
As for cleaning it, try this tip: Put a tiny bit of liquid dishwasher detergent in the bottom, add a tiny bit of very hot water (1/2 cut) and use a bottle brush to scrub the instead. I also use this method on my metal thermoses and glass teapots. It removes all the tea stains every time (now if only I could use it on my teeth!).
