Can I just dump out the juice in my clearo and not clean it, then add a different kind? I've only filled this clearo once but only have 3 clearos and want to try another juice in it. Do I have to clean it? The swap would be between Cappuccino and Cafe Coffee. I'd assume going from a coffee like juice to a fruity one would definitely taste a little weird... I've never cleaned a clearo and since I only have 3 and no B&Ms around here, I don't want to run the chance of ruining one. When I was using cartos I tried cleaning them a few different ways, but they never seemed to come out right...
