Frequently Asked Questions

What material is the GAC 2.5" Ceramic Grinder Black made from?
It is made of ceramic. Clean it regularly and it will perform like day one.
How fast does the GAC 2.5" Ceramic Grinder Black ship?
Orders placed before 2 PM ET on business days are processed the same day. Every GAC 2.5" Ceramic Grinder Black order ships tracked, in plain discreet packaging, typically arriving within 2–5 days.
Why do grinder pieces matter (2 vs 3 vs 4-piece)?
A 2-piece just grinds. A 3-piece adds a storage chamber below the teeth. A 4-piece adds a fine mesh screen that sifts kief into a bottom chamber — the bonus layer that accumulates into a potent reward over weeks of normal use.
What is the kief catcher actually catching?
The screen sifts off trichomes — the resinous crystals that carry most of the potency. Collected kief can be sprinkled on a bowl, pressed, or saved for special occasions. A coin left in the kief chamber helps knock more through the screen.
How do I clean a metal grinder?
Disassemble and freeze it for 30 minutes (resin snaps off cold), brush out the loose material, then soak parts in isopropyl alcohol and scrub with a brush. Rinse, dry fully, and it grinds like day one. Save the iso — evaporate it to recover the resin if you like.
Aluminum vs zinc grinders — is there a difference?
Aircraft-grade aluminum is lighter, machines sharper teeth, and lasts for years of daily use. Zinc alloy is heavier and cheaper — fine for occasional use. If a grinder is suspiciously cheap and doesn't say aluminum, it's zinc.
Why does my grinder get hard to turn?
Resin builds up on the thread ring and teeth. A quick brush-out weekly and an iso deep-clean monthly keeps it turning smoothly. Storing it in a warm spot (not the fridge) between cleans also helps the threads move freely.

How to get it right

1

Load the edges

Place material between the teeth, not dead center - the center pin does not grind. A few firm twists and you are done.

2

Work the kief screen

A coin in the middle chamber knocks extra kief through the screen. Check the bottom chamber monthly - that is the bonus stash.

3

Keep it turning

Brush out after use; freeze then iso-scrub monthly. Clean threads keep it smooth for years.
