Whenever I wash my glass carafe with soap, either I rinse for more than ten minutes or I can still taste the soap - so I don't do that. I usually do successive rinses for a minute, but if I'm feeling serious I use (cheap, store bought) lemon juice and baking soda. If I haven't rinsed those enough, I don't mind the trace of citrus and sodium.
