A re-useable aerosol container is disclosed. Such an aerosol container defines an aperture and an inner chamber for containing a fluid. The aerosol container includes an aerosol valve for dispensing fluid contained within the aerosol container. The aerosol container further defines a neck surrounding the aperture and further includes a plug defining a cavity that is removably insertable into the inner chamber via the aperture. The plug includes a collar surrounding its cavity. The plug collar and the aerosol container neck are so relatively dimensioned and adapted as to be removably engageable in a fluid-tight manner when the plug cavity is inserted into the aerosol container inner chamber via the aerosol container aperture. The aerosol container further includes dry chemical formulation ingredients, disposed within the plug cavity. Such dry chemical ingredients, when mixed with water, are able to produce gas, for purposes of pressurizing the fluid container chamber. The aerosol container still further includes a water-soluble membrane, removably affixed atop the plug cavity, for retaining the dry chemical ingredients within the plug cavity.
