For the pre-buried channel components, everyone should clean them on time. However, we would like to remind everyone not to use strong acids or alkalis in water solutions for cleaning, as it may continue to damage the pre-buried channel components. You can simply clean the surface with cold water or neutralized cleaning solutions, and then wipe them with cotton cloths. Additionally, when cleaning the pre-buried channel components, try to avoid using abrasive cleaning agents or rough fabrics for cleaning or wiping, and also pay attention to the concealed parts of the pre-buried channel components.
