Method of cleaning drinks dispense systems |
(57) A method for cleaning a beverage dispensing system or beer line comprises a two stage
process with a preliminary step of treating the system with a solution of conventional
alkaline beer line cleaner, in order to remove contaminants and to expose raw biofilm
to be treated. This is followed by a secondary treatment with a solution of chlorine
dioxide. The chlorine dioxide solution, comprising between 50 and 1000 ppm of available
chlorine dioxide, is generated in situ by mixing a solid acid, such as citric acid
or isocyanuric acid with a solution of sodium chlorite.
