Would freezing and then scraping work?
I'd prefer that to an alcohol wash, which always seems to leave me with an invisible layer of adhesive oily gunk over everything.
Freezing might help actually, yeah. I've already scraped and brushed it the best I could at room temperature, but when I look at the bottom chamber upside-down I can see kief and plant-matter all through the inner threads of the bottom piece. The rest of it's pristine aside from the grinder blades, and even then they're still pretty well off and shiny as ever.
I've had undesired effects with iso-washing grinders before as well. I didn't get an oily coat or anything the one time I did it, but it seemed to tarnish the silver metal to a deep, ugly and dirty-looking bronze color. That was a pretty good grinder too, but it was only a two-piece so I ended up upgrading after I did that iso-wash and tarnished the metal-- I wasn't sure if that could have any effect on the weed that went through it, tbh.
Both decarbed and water cured weed has little to no smell if smelly flower is your problem.
I just get paranoid when I can smell my tree when it's not in use and everything's stashed away. I've got everything under control except this smelly as shit grinder and I really just don't feel like buying another smell-proof container that's going to be a boof bomb every time I open it up. I'd much rather just have a grinder that contained the smell within itself, but I'm not willing to give up the one I've got now. Give me a minute and I'll see if I can find a link to it or something.
[EDIT: NSFW for pic size
It's just kind of fucked, because this is the only grinder I've had that's ever emanated a smell. I think it may be because the top piece isn't super magnetic and and the bottom isn't magnetic at all-- simply screw on/screw off.
I'm going to look into water-curing. I'm not a big fan of the idea of smoking decarbed bud, though, wouldn't that be a lot like rolling a pure ABV joint?
Not sure how you expect to scrape the small spaces in a grinder... maybe you could with a sewing needle if you wanted to take 600 hours to clean your grinder.
Lol, I'm for sure trying to do that but I could brush it instead. It won't save all of the kief (or even most of it), but I think that after sitting in the freezer for a few hours my grinder brush'll knock a whole lot out of the threads. I could be wrong but it's worth a shot.
(In case you don't know what I mean by a grinder brush, they're almost identical to the brushes that come with beard trimmers:
. i'm squeezing all the juice i can i feel like a crack head.
