The Slick coating is Cali Crusher's proprietary food-grade nonstick treatment applied to the interior teeth, walls, and threads of the O.G. Slick Nonstick Grinder. Sticky strains — particularly indica-leaning rosin-quality flower and fresh harvest material with high terpene content — leave resin residue that gradually clogs grinder teeth, makes threads stick, and reduces grinding efficiency over time. The Slick coating dramatically reduces this buildup, keeping the grinder operating like new for longer between cleanings. The coating is rated food-safe and does not affect the flavor or potency of ground material. Cleaning is also easier with Slick — residue wipes away rather than requiring isopropyl alcohol soaks.
