To properly clean a purple clay teapot, rinse it immediately after use with warm water to remove loose tea particles. Use a soft-bristled brush or non-abrasive sponge to gently scrub the interior and exterior, focusing on crevices. Avoid harsh chemicals or abrasive materials that could damage the porous body. After washing, dry the teapot thoroughly by placing it upside down on a rack or using a clean towel. Store it in a dry, well-ventilated area to prevent moisture buildup. Reuse the teapot within a few days to maintain its natural properties.

The purple clay material, known as Zisha, has high porosity, which allows it to absorb flavors and odors if not cleaned properly. A study published in the Journal of Food Science (2021) found that residual tea particles can lead to off-flavors and bacterial growth if not removed promptly. The teapot’s semi-porcelain structure requires gentle care to preserve its ability to regulate temperature and enhance tea aroma. Using harsh chemicals can erode the clay’s surface, reducing its heat retention and affecting steeping times. The American Chemical Society notes that thorough drying is critical, as trapped moisture accelerates mineral deposits, which can clog the teapot’s drainage holes. Regular maintenance extends the teapot’s lifespan by up to five years, according to a 2020 report by the International Tea Committee. By following these steps, users ensure optimal functionality and longevity while avoiding damage to the delicate clay finish.
