An apparatus comprising: an aerosol valve system including: a container, wherein the container houses a first reservoir, and a second reservoir, wherein the first reservoir is fluidly separated within the container from the second reservoir, wherein the first reservoir houses a first material, and the second reservoir houses a second material that is different from the first material and which acts as a cleaning agent with respect to the first material, a first valve, wherein the first valve is selectively changeable between a first valve open state and a first valve closed state, wherein the first valve is fluidly connected with the first reservoir within the container, wherein the first valve includes an axially extending first valve stem, wherein the first valve stem includes an axially extending outlet channel, wherein the first valve is operative to discharge the first material through the outlet channel when the first valve is in the first valve open state, a mixing chamber, wherein the mixing chamber is fluidly intermediate of the first reservoir and the outlet channel, a second valve, wherein the second valve is selectively changeable between a second valve open state and a second valve closed state, wherein the second valve is fluidly connected with the second reservoir within the container, a cleaning channel, wherein the second valve is in fluid connection with the cleaning channel and is operative to discharge the second material to the cleaning channel in the second valve open state, wherein the cleaning channel is in fluid connection with the mixing chamber of the first valve, wherein after the first valve is changed from the first valve open state to the first valve closed state, the second valve is enabled to be in the second valve open state, whereby in the second valve open state the second material flows through the cleaning channel, the mixing chamber and the outlet channel to clean the first material therefrom. a container, wherein the container houses a first reservoir, and a second reservoir, wherein the first reservoir is fluidly separated within the container from the second reservoir, wherein the first reservoir houses a first material, and the second reservoir houses a second material that is different from the first material and which acts as a cleaning agent with respect to the first material, a first reservoir, and a second reservoir, wherein the first reservoir is fluidly separated within the container from the second reservoir, wherein the first reservoir houses a first material, and the second reservoir houses a second material that is different from the first material and which acts as a cleaning agent with respect to the first material, a first valve, wherein the first valve is selectively changeable between a first valve open state and a first valve closed state, wherein the first valve is fluidly connected with the first reservoir within the container, wherein the first valve includes an axially extending first valve stem, wherein the first valve stem includes an axially extending outlet channel, wherein the first valve is operative to discharge the first material through the outlet channel when the first valve is in the first valve open state, a mixing chamber, wherein the mixing chamber is fluidly intermediate of the first reservoir and the outlet channel, wherein the first valve is selectively changeable between a first valve open state and a first valve closed state, wherein the first valve is fluidly connected with the first reservoir within the container, wherein the first valve includes an axially extending first valve stem, wherein the first valve stem includes an axially extending outlet channel, an axially extending first valve stem, wherein the first valve stem includes an axially extending outlet channel, wherein the first valve is operative to discharge the first material through the outlet channel when the first valve is in the first valve open state, a mixing chamber, wherein the mixing chamber is fluidly intermediate of the first reservoir and the outlet channel, a second valve, wherein the second valve is selectively changeable between a second valve open state and a second valve closed state, wherein the second valve is fluidly connected with the second reservoir within the container, wherein the second valve is selectively changeable between a second valve open state and a second valve closed state, wherein the second valve is fluidly connected with the second reservoir within the container, a cleaning channel, wherein the second valve is in fluid connection with the cleaning channel and is operative to discharge the second material to the cleaning channel in the second valve open state, wherein the cleaning channel is in fluid connection with the mixing chamber of the first valve, wherein after the first valve is changed from the first valve open state to the first valve closed state, the second valve is enabled to be in the second valve open state, whereby in the second valve open state the second material flows through the cleaning channel, the mixing chamber and the outlet channel to clean the first material therefrom.
