I disagree, but that's because I don't like to brew my tea in a pot that has a soft and fuzzy crust inside after brewing lots of batches of tea. That's why I tend to brew it one mug at a time now, and the mug gets washed with the dishes. I use a small stainless steel tea strainer over the top of the cup and don't pour water directly into the strainer or it washes too much of the little fine grounds into the cup. But McGrath is right--be very careful to not leave behind any soap in anything for tea. Ugg, but dish detergent is easily noticable and you need to throw out the batch if you can smell or taste it in your tea.

I had forgotten about the tea/tissane information. And since none of the boxes come labled tissane I expect that term will gradually go away completely. (To my American ears "tissane" sounds like eating or drinking something akin to plastic wrap).
