  • Publication number: 20110131742
    Abstract: A foldable cleaning pad sized for placement in a user's clothing or golf bag pocket includes a substantially fluid impermeable backing layer, and an inner cleaning layer having a fluid absorptive portion. The cleaning pad is configured to be folded in half about a mid-plane fold axis, so as to present outwardly only the backing layer. Peripheral edge portions of the cleaning pad are provided with pairs of magnets positioned in symmetrically spaced locations on each side of the fold axis. The opposing pairs of magnets are positioned with the opposite magnetic polarity so that when the pad is folded, the magnets are provided in juxtaposition such that the magnetic attraction therebetween substantially prevents the leakage or transmission of fluids, moisture or other debris therebetween from the interior of the folded pad. The inner cleaning layer of the pad is provided with both a fluid absorptive portion, as well as an abrasive scrubbing portion.
