Isopropal works....
Careful with the iso alcohol. I tried cleaning my acrylic grinder with it and the whole thing ended up getting cracks all through it.
I now use a nice 4 piece grinder with kiff collection... it's awesome. I'll never use one of those little grinders again.
Yes its must be a 3 piece, and I'm not talking about 2 bandaids and a cork. He wasn't sure why it didn't have a kief screen so he gave me one, I didn't get a fourth section to put it over. No sweat, they are good folks, I'll get it taken care off. In the meantime the grinder I posted in the blues thread does a hell of a job, and every once in a while you get to lick the bowl. Thanx for the info. + rep VVI recommend getting the 3" ones. The 2.5" is a tad small and the 4" is huge!
