Abstract: An apparatus for cleaning the magnetic head of a card reader, particularly, a generally rectangular shaped semi-rigid card, wherein at least one aperture is sized and positioned on the apparatus to allow the magnetic head of a card reader to protrude into the aperture. The aperture is at least partially covered with an absorbent material which is bonded to the apparatus and may be presaturated with a cleaning solvent. As the apparatus passes through the card reader, the aperture covered by the semi absorbent material conforms to the entire convex surface of the magnetic head, and effectively removes particulate matter on the magnetic head. The apparatus, without the cleaning solvent, is then used to remove any remaining particulate matter raised by the cleaning solvent to prevent settling of residue.
