interesting notion that rice might be of some help.
sounds good to me!

at the coffee shop i worked at, we sold burr grinders/coffee mills
and it is recommended that one puts uncooked/raw white rice through
the grinder to clean off the burrs -- if / when they get gummed up from
oily coffee beans ..
