Abstract
A device and method can remove a scratch-off coating that initially conceals information. The device has a rubbing member including a melamine open cell foam. The device's structure includes a body with a fluid chamber that communicates with a distal opening. The rubbing member is mounted at this distal opening. The structure includes a scraping element located at the rubbing member. The melamine open cell foam and the scraping element are simultaneously pressed against and moved across the scratch-off coating until it is removed and retained in the foam sufficiently to reveal the concealed information.
Claims15
A device for removing a scratch-off coating that initially conceals information, comprising:
- a rubbing member comprising an abrasive, open cell melamine foam that is wetted with water;
