Does anyone know if there's another way of cleaning the grinder short of taking it apart? I have a spice.coffee grinder that's like a miniature food processor, and I clean it by grinding uncooked white rice. It uses whirring blades in a small open container, however, which makes it really easy to brush out the resulting rice flour. I am concerned that taking the same approach with the grinder in my Estro Barrista would just add to the gunk clogging up the grinder. Seems like there ought to be something about the same size and consistency as coffee beans, but without all the oil, that I can run through the grinder to clean off the oily coffee residue.
