Pre-warm the teapot before brewing to maintain optimal temperature.
-
Avoid soap on porous materials like unglazed clay; rinse with hot water only.
-
Rinse and dry thoroughly after each use to prevent mold and staining.
-
Do not mix different tea types (e.g., strong spices vs. delicate greens) if using porous pots.
-
Store with lid open or slightly ajar to prevent musty odors.
