To properly clean and maintain your porcelain tea set, you need to do more than only wash it once in a while. You should only ever wash your tea set by hand with warm or cold water and a gentle sponge. Stay lucid about what type of cleaning agents to use, being more abrasive might badly scratch the surface. Allow the pieces to air dry after washing or wipe them dry with a towel, making sure no water spots are left on them. When it's time to store them, make sure to store them in a padded storage box or wrap them in cloth to avoid any chipping. Try not putting the pieces on top of each other or piling them. By adopting these measures and following simple but effective care advice, you can ensure that the performance and beauty of your porcelain tea set is retained for many many years.
