Abstract
A method and device for cleaning the inside of a liquid dispensing tube that is contaminated with a previously dispensed liquid. The contaminated liquid dispensing tube is filled with a cleaning fluid. The liquid dispensing tube is then impacted with an impacting device. The impacting of the liquid dispensing tube creates pressure waves in the cleaning fluid. The pressure waves dislodge the liquid contaminate from the inside of the liquid dispensing tube while a flowing cleaning fluid flushes the liquid contaminate out of the liquid dispensing tube.
