HIC Kitchen's Chainmail Cast Iron Scrubber is specially designed to clean cast iron pans, woks, and griddles easily without removing the seasoned surface. Lightweight and strong. The built-in silicone honeycomb core dries quickly, and won't sour or produce bacteria. The outer chain quickly scrubs away baked-on, caked-on food bits without removing the seasoning, that coveted buildup that accrues over time to create a naturally non-stick surface. It's dishwasher safe for easy cleanup. Not intended for pans made from materials other than cast iron.
