Before first use, put 5-10 grams of tea into the cast iron teapot and brewing for about 10 minutes, pouring away the water after
it is done boiling. Repeat the produce for 2-3 times until the water is clear.
Recommend not pour over 70% of capacity water into the teapot, avoid cleaning the teapot with detergent, brush, or cleaning
implement.
Dishwashing detergent is not recommended, simply clean it with water is enough.
Dry after each use to Avoid Rust. Take the lid off while drying, and the remaining water will be evaporated slowly. A tannin film
will cover the interior, which is the reaction of tannin from tea leaves and Fe2+ from the iron teapot, and it will help remove
the odor and protect the teapot from rusting.
