Hi all. I'm new to the community. I probably have 6-8 cups of tea a day. Lately my favorite has been Honey Vanilla Chamomile (Celestial) and To Life (Teavana) and Honey Ginseng and Mate Latte (Republic of Tea). I just got the Teavana Hobnail cast iron teapot in black but I don't have a lot of loose teas. Do any of you have tips for keeping the cast iron pot clean with minimal chemicals (I'd prefer not to use any if possible). Thanks.
