Cleaning a teaière is not about making it sparkle, but about preserving the balance between hygiene and patina, the latter sometimes playing an essential aromatic role. The earthenware teapots made from unglazed clay, particularly those made from zisha, must never come into contact with soap. Porcelain and enamelled cast iron allow for more conventional care, but remain sensitive to certain products. Adapting the method to the material prevents irreversible damage to an object that may be precious.
Unglazed clay teapots: plain water is enough
Zisha or Yixing clay teapots have a porous structure that gradually absorbs the essential oils and aromatic compounds of the tea brewed over repeated uses. This phenomenon, known as seasoning, gives the teapot an olfactory memory that often improves the quality oftime subsequent teas, provided that, ideally, one teapot is dedicated to a single family of tea.
Using soap or detergent on this type of clay would permanently impregnate its pores with chemical residues, irreversibly altering the herbal teas following ones. A simple rinse with plain hot water, followed by air-drying with the lid open, is more than sufficient.
Porcelain, glazed stoneware and cast iron: conventional care
Porcelain or glazed stoneware teapots, with a non-porous vitrified surface, can be washed in warm water with a little mild washing-up liquid, then rinsed thoroughly to remove any residue of added fragrance that could contaminate the next herbal teas.
Japanese cast-iron teapots, known as tetsubin when enamelled on the inside, should be rinsed only with clean water, without soap or an abrasive sponge, to preserve the protective enamel against rust.
Descale without damage
Limescale deposits, unlike aromatic patina, can dull the inside of a teapot over time, particularly in hard-water regions. A mixture of hot water and diluted white vinegar, left to stand for around thirty minutes and then rinsed thoroughly, dissolves limescale without resorting to harsh descaling products; this method should be reserved for enamelled teapots and never used on unglazed clay.

Frequently Asked Questions (FAQ)
- Can a clay teapot be put in the dishwasher?
- No, never. The dishwasher exposes porous clay to harsh detergents and heat that can create microcracks. Rinsing by hand with plain water, without any product, remains the only suitable method for this type of teapot.
- Should a teapot be dedicated to a single type of tea?
- For unglazed clay teapots such as zisha, this is strongly recommended, as the porous material retains the aromas of one family of tea, oolong or pu erh, for example, and could contaminate another. Enamelled or porcelain teapots do not impose this constraint.
- How can a persistent odour be removed from a teapot?
- For an enamelled teapot, an extended rinse with plain hot water, possibly followed by complete air-drying, will generally remove odours. For unglazed clay impregnated with an unwanted tea, it is best to reserve it permanently for that same aromatic family.
