A method is provided, which includes generating a cleaning liquid by a combination of a sparging process and an electrochemical process that produces an anolyte and a catholye. The invention provides program data corresponding to each program. The second side has a rib extending from the second side. A tool may be inserted through an opposing aperture in an opposing second wall of the cap and used to manipulate the fastener head and thus the shank to secure the object to the substrate via clamping of the object between the fastener head and opposing second wall of the cap on one hand and the substrate on the other hand. The user can therefore replace the failed capacitor as part of scheduled maintenance, reducing maintenance and operating costs caused by unexpected, unscheduled maintenance. The guard ring has a brittleness greater than a brittleness of the insulating layer.
