Improvements in an aerosol can liquid dispenser to provide a method to dispense a limited amount of fluid from within an aerosol can and to hold the fluid in a reservoir so it can be intermittently used. An operator may only dispense a few drops of liquid and use only a fraction of the dispensed quantity. The collection reservoir is located in a semi protected enclosure to minimize air flow over the fluid thereby reducing evaporation. A secures mechanism allows the dispenser to be quickly and easily mounted and removed from the top of an aerosol can. A removable cap closure to reduce evaporation of any dispensed fluid held in a reservoir. An overflow reservoir collects any excess fluid where it is held in a separate chamber and can be reclaimed.
