Decayed portions of potatoes are removed by supporting and advancing the potatoes on a series of rollers relative to a plurality of water spray nozzles with rubber fingers being mounted on some of the rollers. The rubber fingers contact the potatoes with sufficient force to penetrate the decayed portions without damaging the peel or other sound portions of the potatoes while water sprays contact the potatoes with sufficient force to remove the penetrated decayed portions while leaving the remaining portions intact.
