Abstract

A method of cleaning a metered dose spray device, and a cleaning composition for such cleaning, to prevent the device from becoming clogged with medication. The method includes removing the aerosol can containing the medication from the actuator, placing an aerosol can containing a cleaning composition in the actuator, and dispensing the cleaning solution through the actuator. The residual medication is thereby removed from the actuator. A sufficiently small quantity of cleaning composition remains in the actuator so that the cleaning composition itself will not clog the actuator. Additionally, the cleaning composition is non-toxic, so that residual cleaning composition remaining in the actuator will not harm the user when a subsequent dose of medication is dispensed.
