A scraper device includes a scraper fixture which is adapted to be placed in a working position adjacent to a surface to be scraped. At least one flex arm is connected at its proximal end to the scraper fixture and includes a distal end extending from the fixture toward the surface to be scraped when the scraper fixture is in the working position. A scraper plate is located at the distal end of the flex arm and extends at an acute scraping angle with respect to the surface to be scraped when the fixture is in the working position. In this position, a scraping edge of the scraper plate makes contact with the surface to be scraped to provide a scraping action as the scraper device is driven over the surface to be scraped.
