Apparatus (2), for dispensing a chemical, including an aerosol container (10), which contains the chemical, the aerosol container provided with magnetic material, a solenoid (12) which extends around the aerosol container (10), and a control switch (16) and timer (18) to control actuation of the solenoid (12). The actuation of the solenoid (12) causes the aerosol container (10) to behave as the solenoid core and the aerosol container (10) moves from a non-dispensing position to a dispensing position.
