Abstract
Abstract A substantially cylindrically shaped rubber food scraper is mounted on a steel dish cleaning table over a refuse container located below the table. The interior of the scraper is substantially hourglass shaped and includes a plurality of magnets embedded in the interior wall thereof adjacent the reduced diameter portion. Food and waste paper scraped from dishes pass through the scraper to the container below but stainless steel flatware is attracted to and held by the magnets.
