A lens and/or a view screen of an electronic device having at least one case can be cleaned by wiping the view screen with a cleaning component wherein the cleaning component is configured to selectively couple to the at least one case or some other substrate using a magnetic attractive force. The cleaning devices may have secondary applications such as securing fly fishing lures, activating or deactivating a device having a magnetic switch, or preventing sunglasses from sinking. They may also be manufactured without a cleaning component for use with the secondary applications.

A method and apparatus for substrate, such as glass substrate, surface cleaning include one or more nozzles to deliver a cleaning fluid to one or more edges of a substrate and a roller that includes a plurality of angled channels on the outer surface of the roller. The roller is configured to contact a surface of the substrate and the angled channels are configured to laterally channel fluid and particles toward opposite axial ends of the roller.
