ABSTRACT:
The invention provides a jewelry cleaning arrangement including a housing and a cleaning bath tank formed of an electrically conductive material. The cleaning bath tank is supported within the housing and is connectable to an electric potential. An electrical contact member extends sealingly into the interior region of the tank. The electrical contact member is electrically insulated from the tank and is connectable to an electric potential. A non-conductive insert member is positionable in the tank and movable between a cleaning position and an elevated position. The non-conductive insert member includes a support surface upon which jewelry may be placed. A jewelry engagement conductive member is provided supported on the non-conductive insert member support surface. The jewelry engagement member includes a contact portion engaging the electrical contact member when the insert member is positioned in the cleaning position within the tank. The cleaning tank is fillable with conductive fluid to allow electrolytic action betweeen the tank and the jewelry to be cleaned with the jewelry being placed at negative potential and the tank being placed at positive potential.
