This S&B grinder gets mentioned quite a bit in this thread. Most people are a bit wary of using ISO on it for worries of the ISO leaching the plastic. A hot water bath and scrub with some regular washing up liquid and a nail brush should do the job.
I'd recommend putting the grinder in the freezer for an hour. Get a pick or wire brush and scrape as much of the goodies built up as you can and before clean it.
