How to Season and Protect Your Cast Iron Kettle from Rust

What is Cast Iron and Why Does It Rust?

Cast-iron cookware has been the heavyweight champion in terms of heaviness and durability, from ancient kettles to modern must-haves. It is good for boiling water, steeping tea, or making coffee because of its good heat retention.

The melting of iron takes place first, which then solidifies into molds to form the material. When maintained well, cast iron develops a non-stick surface by nature, thereby increasing the utility it possesses.

The fight to keep cast-iron cookware free from rusting is never easy. Iron, when combined with oxygen in the atmosphere, gives off iron oxide, which is colloquially known as a substance that corrodes cast iron. 

The only thing that hastens this process is exposure to humidity for extended periods or even water left in the kettle. Cast iron also tends to rust easily because its surface is porous and tends to absorb moisture.

It requires seasonal maintenance for the building of rust protection that will extend its useful life. It needs seasoning, which means building a barrier that keeps the kettle from rusting, making it less likely that food will stick, and it becomes better at retaining heat.

How to Season a Cast Iron Kettle: A Step-by-Step Guide:

The first thing you want to do with a cast-iron kettle is clean it. In preparation for cleaning, remove the kettle’s rust or old seasoning, along with food residue. If needed, clean it with hot water and a soft brush, together with some soap. 

Harsh abrasives or cleaners will make scratches in the metal. Dry the kettle completely following the cleaning with a towel to get rid of any moisture.

You should look for a high-quality seasoning oil that does not smoke when heated and does not polymerize into a thick, protective film. Canola oil, vegetable oil, or flaxseed oil will all do the trick.

In a preheated oven set to 450°F (232°C), invert your cast-iron kettle and set it on the center rack. To collect any oil droplets, lay a sheet of aluminium foil on the bottom rack. Cook the kettle in the oven for about an hour, or until you can feel the oil polymerizing and forming a protective layer. This prevents rust by sealing the cast iron surface.

Do this two or three times to get the best results from your cast-iron kettle. This is the proper procedure to follow whether you are using a brand-new kettle or if you have previously removed the old seasoning.
