Abstract: An electrical edge connector cleaning device consisting of an essentially planar board having embossed areas at opposite ends that operate as an abrasive due to parallel striations used to create the embossed areas. The device is configured such that a first opposite end operates to clean male edge connectors by employing leverage means to assist in burnishing the connectors and a second opposite end operates to clean female edge connector sockets by embossing a top and a bottom surface of a lip that is then repeatedly inserted into and removed from a female edge connector socket to burnish the contacts.
