I do an Isopropyl bath then a quick brush with a tooth brush. Makes it grind like new.

Ive never bathed by grinder in isopropyl in 6+ years and it still grinds like new every time I clean it with my pocket knife. But I did get a steel grinder to make sure I can scrape all I want without getting aluminum in my weed

You’re probably still getting some steel in the weed. It is very unlikely the knife and the grinder share the exact hardness.

But I’d rather have steel than aluminum in my weed. Aluminum oxide fumes are carcinogenic when inhaled, so I’d rather avoid it.
I realize worrying about cancer when talking about smoking is ironic, but still.
