1. When maintaining ceramic mugs, you can choose kitchen bleach: first dilute kitchen-specific bleach in a large basin, and then soak the mug overnight. After washing with water the next day, the tea stain will magically clean up.
2. You can also use the peel to replace the vegetable melon cloth, dip it in salt, and then use it to brush the tea stains, which can also achieve unexpected good results. If the peel is not available, a little vinegar will have the same effect.
3. At the same time, use toothpaste to scrub, and then rinse with water.
