Synopsis: Did you just receive replacement grinder burrs and you notice rust, stain or think they are corroded ?
Commercial grade steel burrs are made from high-carbon steel, NOT stainless steel as is often mis-stated. Carbon steel will rust if exposed to even slight humidity if not “seasoned” or protected with some sort of oil/lubricant. Rust is virtually non existent in coffee grinders that have had a few pounds of coffee put through them, even after periods of non-use. This is a result of “seasoning of the burrs” similar to cast iron cookware.
