Home > Do you know how to protect cast iron teapot

Do you use cast iron teapot? Do you know how to take care of it? You should pay more attention to protect cast iron teapot.

First, treat external rust with olive oil and finely grained salt

Any rusted portions on the exterior of cast iron teapots should be rubbed lightly with a solution of olive oil and fine-grained salt. The rubbing motion has to be gentle in order to avoid scratching and spoiling the finish of the teapot.

Second, you could just purchase cast iron teapots that have been glazed with porcelain

To omit altogether all rust-prevention routines for your cast iron teapots, consider purchasing those vessels that have been glazed with porcelain. Porcelain will keep the metal from coming into contact with oxidizing agents. Even if some rust should form it is effectively kept out of the tea by the porcelain layer. Residue will still cling to the porcelain and you will see them as stains that eventually take on their own texture. These residues should be left alone, as already mentioned. Quite naturally, you shouldn't even think of applying olive oil and salt on porcelain-glazed cast iron teapots.

Third, do not remove the residue that is left in the teapot

Each time you brew tea in cast iron teapot, you cause a thin film of residue to form along its inner walls. This residue is mostly made up of tannates of the various amino acids (tea has all 20 of them) that are found in tea. In a word, the residue inside your tea vessel contains a great deal of tannin. Because tannin is a powerful anti-rusty substance, you should allow the residue in your teapot to accumulate. In that case, rust will simply be converted into iron tannate which is seen as a black-blue precipitate on the vessel's inner wall. Obviously, the more you brew tea in a specific teapot, the more protected you are against rust. Some people recommend rubbing the inner wall with olive oil and salt. That solution is fine if you don't mind the hint of olive oil in your tea and if you can reach far enough inside your cast iron teapots to do that. Remember some of them may be flattened in structure.

Finally, pour out the liquid after you are done

Cast iron teapot won't take kindly to being left unattended after you are done with them. They are likely to get rustier after that. So when you are done with using them, you should pour out the remaining liquid, rinse the teapot, invert it so it can drip dry and dry it with a warm air blower. Never use detergents or dish-washing preparations as their odor may stick to the walls of the cast iron teapots and spoil your tea for a long time. This is especially true if any oil has been used in those preparations, making it likely that they produce oily residues on the teapot which will become precipitated and permanently attached to the wall the next time you brew your tea.

Knowing how to protect the cast iron teapot, do it from now on.
