How to Take Care of a Cast Iron Teapot

Do you love to unwind and relax with a cup of tea? Do you appreciate an excellently prepared cup? You know that for the perfect cup, you require the ideal equipment, which is the cast iron teapot. Cast iron teapots are ideal because they are made from strong metal, making them durable. You get to enjoy many years of expertly prepared tea. These teapots will undoubtedly outlive almost all other equipment in your kitchen. How awesome is that!

Further, the iron used is great for thermal insulation, a key component in making excellent grade tea. This feature makes it similar to a thermos because of its heat distribution, ensuring your tea stays at a constant temperature for longer. The traditional Japanese cast iron teapots are ideal for every kitchen as they come in various traditional and modern styles.

However, taking good care of your teapot ensures longevity. You will need to give it some tender love and care so that it serves you longer. Care begins with cleaning and maintaining your teapot so that it remains as good as new.

How to clean a cast iron teapot

Cleaning a cast iron teapot calls for a unique technique from the traditional cleaning techniques you already know. Cleaning the teapot as it should be is what makes your teapot last longer and stay in good shape so that you enjoy using it for an extended period.

  • Before you begin cleaning, ensure your teapot is empty and has cooled off. Cooling is essential as it allows the metal to shrink back to normal, making it easy to wash.
  • Begin by rinsing your teapot with warm water without adding any detergent.
  • Use a soft cloth or sponge to wash your teapot. Rough washing pads will damage the interior of your teapot by scratching it. When the inner coating’s cover is removed, rusting is inevitable. Rust will, in the long run, destroy your teapot.
  • After rinsing, gently wipe the pot with a soft cloth. Wipe the entire interior and the outside without forgetting the undercut parts and the shoulder.
  • Place your teapot up-side-down on your countertop or rack, ensuring the pot receives ample air to dry.
  • Clean the infuser with or without soap. The infuser holds your tea leaves inside the teapot. You can hand-wash it or use a dishwasher. Ensure you remove all tea leaf particles from the gaps on the strainer.

After use, it is vital to give your teapot the necessary care.

  • Allow it to cool before you dry it.
  • Rinse it with warm water after drying.
  • Wipe it dry, inside and outside, when it is still warm.
  • Air-dry it upside down with the lid off.
  • When washing, it is advisable to hand-wash your teapot as a dishwasher cannot provide the care that your teapot requires. Only human hands can deliver quality care for your teapot.
  • Avoid using detergents on your teapot at all costs. They will damage the enamel and iron in the teapot. Additionally, the enamel may absorb the smell of soap and transfer it into your tea.
  • Ensure your teapot is completely dry inside and outside before storage to prevent the formation of rust.
  • Keep salt and oil away from your teapot as they are corrosive. Oil can also stain your teapot.
  • Do not allow steeped tea leaves or water to overstay in your teapot, as this may cause your teapot’s interior to stain. The stain may, in the long run, cause damage to the protective coating.
  • To keep your teapot looking glossy, you can polish its surface with a cloth soaked in tea. Polishing will also prevent rust.
  • When hot, the iron may stain your tabletops or linen cloths. It is advisable to place your teapot on a trivet or dish towel.
  • Lastly, it would be best to not put your teapot directly over an open flame or microwave it. It is not designed to be exposed to fire.

How to clean a rusty cast iron teapot

  • If rusty, scrub off the rust gently with a soft-bristled brush. This will leave your teapot’s crust glowing.
  • Rinse the pot with some water to ensure you remove every rust residue.
  • After rinsing, fill your teapot with boiling water and add tea leaves into the water. Cover your teapot and allow the tea leaves to steep for 30 minutes.
  • Drain the tea. The tannic acid in the tea will react with any rust and will form a natural seal. The seal will bring rusting to an end, never to happen again. Do this often to preserve your cast iron teapot.

Avoid using harsh chemicals to remove rust as they are toxic and will damage the metal.

  • Position the infuser basket accordingly and then measure your tea leaves. Ideally, most teas will require a teaspoon of tea leaves per six ounces of water.
  • Pour the boiling water onto the tea leaves.
