Specifically the screen. I've had this box for like 10 months now and its starting to accumulate alot of gunk in the screen. Usually when my grinder screen looks like this I give it an iso wash and yeild some hash. Cant do the same for this because its made out of wood. Anyone got any ideas? I was thinking brushing it will a metal brush above a peice of paper but I figured someone here would have a better idea. So blades, lets hear it..how do we clean our wooden keif boxes? and can it yeild some smokeable material?
