K people, lets not forget what the problem is.. most likely its due to the fact that the threading is stuck from gooey THC trichs... what is THC? a fat. Now, how are lipids soluble? in either more fat or alcohol (thats why soap is fat and another agent)...

Try either some rubbing alcohol, and/or heating up the part of the grinder... the heat combined with the dilution of the trichs and plant matter should be enough to open after a little force is applied...
NaughtyDreadz Reviewed by NaughtyDreadz on . Grinder Problems Hello. I have a metal grinder with a screen on the bottom that collects kiff. The problem I am having is that the bottom part, the part where the kiff is collected, seems to be stuck and wont move. Ive tried using plyers, but it seems to only leave scratches on the grinder. Any suggestions on how to get this open b/c im going nuts not being able to smoke my kiff. Rating: 5
