Cleaning burr coffee grinder I have a medium-end, drop-through burr espresso coffee grinder (a Solis Maestro Plus).  I haven't cleaned it since I first bought it, and I thought it was about time.  Both the plastic bean funnel and the grounds drawer were coated in extremely stubborn caked-on coffee oils and grounds.  So, some questions:


Getting the caked coffee oil off the plastic parts was very difficult, requiring multiple soakings in hot water and citrus-based dishsoap.  Was there an easier way to do this?
How do I clean the burrs themselves, now?  I can't remove them from the machine.  Presumably I can't use water, and I certainly can't soak them.


Thanks for any advice!
I use Minute-Rice to clean mine (any instant-rice will do - it's partially cooked, so it's softer than raw rice and does a better job cleaning).  I just run a bunch of rice through until it's coming out clean, then run some old beans through before using it for coffee.

Here's a Youtube video on it.  I'm sure there are tons more.  Check out the CoffeeGeek or Home-Barista forums for more information than you ever wanted.
