Abstract

A method for cleaning returnable bottles and similar containers used in the food industry. The method uses an enzymatic solution during the cleaning process. The cleaning results are at least as good as conventional methods, without requiring an increase in the duration of cleaning. The method substantially reduces bottle corrosion and waste water pollution compared to conventional methods.
