A magnetic scraper for manually cleaning contaminated surfaces, such as commercial kitchen exhaust duct systems, is disclosed. Two sharpened blades are positioned opposite one another secured to a body portion. An elongated, extendable arm pivotally connected to the body portion allows propelling the scraper blades either forward or backward in any direction over the extended distances imposed by duct geometry. A magnetic base surface provides self position maintenance of the body portion of the magnetic scraper. Precision dimensions over the length of the scraper body portion and the angle of blade placement permits smooth manual degreasing throughout the varying duct configurations.
