Owners of the “smart” column HomePod from Apple, released on sale in February 2018, complained that it leaves white rings on wooden furniture. The company said that this “there is nothing unusual” and advised simply to wait until the traces disappear themselves.
Traces can be caused by a lubricant that circulates between the rubber base and the surface of the table. They will leave a few days after the column is removed from the furniture.
In case if the traces themselves do not disappear, Apple advised to clean the surface with a tool recommended by the furniture manufacturer. If nothing helps, the company suggests placing the column elsewhere. However, HomePod is not designed to be placed on soft surfaces or fabrics, because this affects the sound quality.
