1. When the surface of the bone china cup is stained with oil, it can be cleaned with warm water, and the water temperature is below 80 ℃; if it is not easy to clean, just add a little vinegar to the water to clean it, do not use detergent
2. If the surface of the bone china cup is scratched, it can be gently polished with toothpaste; when cleaning with a damp cloth or hands, attention should be paid to light force, not too much, to avoid scratching the porcelain
3. If the purchased bone china cup has no mark and is available in a microwave oven, do not put it into the microwave oven for heating, otherwise it will corrode the gold edge
