The invention relates to a method and system for cleaning beverage tubes, in which the set of beverage tubes includes a set of tubes (17, 26) from a tank (30) to one or several dispensing devices (18), and possible cooling, amount calculating, or other devices (11, 12, 15, 16). The set of distribution tubes is cleaned in the following stages: - cleaning fluid is fed into the tubes from one end and the liquid already in the tubes is drained out of the opposite end, - the cleaning fluid is allowed to act for a set time, - the cleaning fluid is flushed out with flushing fluid by feeding in a corresponding manner in to the tubes and draining the cleaning fluid out, - the line is filled with the beverage being dispensed at the same time draining the flushing fluid out of the line. At each stage, each fluid is identified by means of its electrical properties from the end of the tubes opposite to the feed, and this feed is terminated by set criteria, after which the process goes on to the next stage.
