1. When using a dishwasher, choose a dishwasher with a “porcelain and crystal” washing function.
2. Porcelain decorated with gold and platinum edges should not be heated in microwave ovens.
3. The pH value of the lotion must be between 11-11.5. When washing with clean water, the water temperature should not exceed 80 ℃.
4. Do not immerse the hot cup directly in cold water to avoid damage to the porcelain due to rapid temperature changes.
5. If scratches, you can use toothpaste to polish.
6. If there are tea stains, use lemon juice or vinegar to clean.
