Common Knowledge on Daily Maintenance of Household Porcelain

1. It must be cleaned by hand; a dishwasher should not be used. If hand washing is truly not desired, then a dishwasher with a “ceramics and crystal” cleaning function should be chosen.
2. The pH value of the lotion must be between 11 and 11.5.

3. When washing with clean water, the water temperature should not exceed 80℃.

4. Do not immerse a hot cup directly in cold water, as this may cause rapid temperature changes that could damage the porcelain.

5. If there are scratches, you can gently polish them with toothpaste.

6. If there is tea stain, it can be cleaned with lemon juice or vinegar.
