The spray gun includes a primary port for receiving a primary material such as adhesive or similar materials, for dispensing. The spray gun further includes a secondary port to receive an aerosol-based cleaner which is stored in an aerosol container within the handle of the spray gun. The valves associated with the primary and secondary ports are sequenced such that during ordinary depression of the trigger to apply the primary material, the aerosol-based cleaner is momentarily "poofed" through the nozzle to clean the nozzle prior to the application of the primary material. After the primary material has been applied and the trigger is released, the aerosol-based cleaner is again momentarily "poofed" through the nozzle to clean the nozzle.
