The present application relates to a hand-held steaming device (10). The hand-held steaming device comprises a steam generating surface (4A), a heater (5) to heat the steam generating surface, a water supply unit (6) to supply water to the steam generating surface and a sensor (12) configured to detect the inclination of the steam generating surface with respect to the horizontal. The hand-held steaming device further comprises a controller (11) configured to perform a user selectable descaling process wherein the heater is operated to heat the steam generating surface to a first temperature and the water supply unit is operated to supply water to the steam generating surface at a first flow rate to remove scale from the steam generating surface. The controller is coupled to the sensor and is configured to prevent the water supply unit from supplying water to the steam generating surface at the first flow rate and/or the heater from heating the steam generating surface to the first temperature when the descaling process is selected if the steam generating surface is inclined by more than a first predetermined angle from the horizontal (X-X).
