A portable ice and snow scraper suitable for clearing glass surfaces such as windscreens that uses a heated and pressurised air flow to rotate a cylinder containing scraper blades. When the scraper is applied to a glass surface the rotating blades and heated air clears the ice and snow from the glass. The device body 7 contains air inlet holes 13, an integrated motor and fan 15, and heating element 16 powered by a rechargeable battery unit 9. The blades 1 are partially covered by a shield 2 that is attached to the flow pipe 5 that directs air into the cylinder and blades wherein both shield and blades are heated by the air flow. Preferably the shield has a fixed scraping blade 4 when the device has no power and slot 3 for air to escape. Preferably the blades have sharp edges made of non-scratch plastic. The blades may have metal cylinders embedded into holes (see fig 3), that assist in directing air flow, and conducting heat across the blade. Alternative attachment (24, fig 6) has a single fixed scraper blade, and a series of holes that direct the heated air flow above the scraping edge.
