Precautions for cleaning and maintenance of ceramic tableware

1. Be sure to wash it by hand. Do not use the dishwasher. If you really don’t want to wash by hand, you should choose a dishwasher with porcelain and crystal washing functions.

2. Do not put it into microwave oven for heating, or it will corrode Phnom Penh.

3. The PH value of detergent must be between 11-11.5, because the ceramic is alkali resistant.

4. When washing with clean water, the water temperature shall not exceed 80 ℃.

5. Do not immerse the hot cup directly into cold water, so as not to damage the porcelain due to rapid temperature change.

6. If there are scratches, you can polish them slightly with toothpaste.

7. If you have tea stains, you can wash them with lemon juice or vinegar.
