Copper handicrafts should be placed indoors in a dry place and do not require special maintenance on a daily basis. They can be wiped with a clean cotton cloth during cleaning. Do not use cleaning agents and hard wipes containing acidic substances to avoid corrosion and damage to the surface of copper ware. Because the oil and moisture in fingerprints are one of the important reasons for the formation of "copper green", please wipe them as soon as possible after touching to avoid the phenomenon of "copper green" after a long time.
