Prop 65 is placed on all our cast iron. It has nothing to do with where the item was manufactured but rather a precautionary label we add to protect ourselves from the many lawsuits that are going on in California. We are not aware of any certain chemical, which is above any Prop 65 minimum level.
There are a few ways to do this. The easiest way is to pour a can Coca-Cola and let the soda break down the rust. The time will depend on the severity of rust. After the rust is removed be sure to wash and re-season the cast iron.
As a premium cast iron manufacturer, we only use all-natural iron and test our products for toxins to ensure quality in every piece. All Camp Chef cast iron comes pre-seasoned with an all-natural seasoning made from 100% plant oils, giving our cast iron a dark finish that is ready use right out of the box.
