The scraping portion is connected to the handle and has a scraping edge configured in such a manner so as to permit the scraping of a surface by the scraping edge by pushing the handle with a force in a generally forward direction over the surface. The scraping portion, scraping edge and handle are generally aligned in a direction parallel with the force applied to the handle during scraping of a surface. The gas outlet is proximate to the scraping edge and is configured so as to direct gas in a forward direction toward the scraping edge generally parallel to the force applied to the handle. This invention has a multitude of uses and is practical for home and commercial applications involving removal of grease, dirt, paint, etc.
