How to use the newly bought ceramic tableware?

Newly bought ceramic tableware can be cleaned according to the following steps:

1. Soak and wash with hot water first, mainly to remove dust and water-soluble residues attached to the surface of the tableware.

2 Add 4%~5% vinegar to water, boil and soak in tableware for 1~2 hours to neutralize trace alkaline residues; new ceramic tableware contains a small amount of free lead, which can also be removed by this step.

3. Put the washed ceramic tableware in salt water and cook for a while, so that its service life is not easy to break and use for a longer time.
