Rust can be called a product of metal oxidation, which appears due to the reaction of metal with oxygen with the participation of water or some aggressive chemicals. Only plain carbon steel will rust easily, and all other metals are less likely to suffer from the effects of corrosion. If rust spots were found on the surface of the cast iron,

Rust stains are ways to negatively affect health, because their particles get into food. For this reason, it is impossible to cook in dishes with corrosive elements, and first you should completely get rid of them.

If the cauldron began to rust not from the inside, but from the outside, you will need to immerse it in a larger container with the same solution of water and vinegar.In the absence of the effect, it is allowed to boil in a vinegar solution with the addition of salt for 2 hours over low heat, and then you can clean off the remnants of rust, and it will be much easier.
Strong cleaning agents
If simple abrasives of natural origin do not help, then you can use special cleaning agents made on the basis of salt acid, which can cause the rust to turn into a powder.
