This video answers the question "does cleaning your CDs or DVDs with a banana work?". First, take a freshly cut piece of banana and rub it in circles on the disk gently. Rub it well for about two minutes. Then, take the peel and rub the inside of the banana peel in circles on the disk for about three minutes. The peel apparently provides some wax for the cleaning process of the disk. Next, take a cotton cloth and wipe it around the disk for as long as it takes to clean up the banana from the disk. Then use glass polish and a cotton cloth to buff the disk. The scratches appear to be cleared up.
