Abstract: The instant invention is a decontaminating process for reducing the surface tension of a biofilm allowing for the removal of the biofilm and control of underlying bacteria. A solution consists of saponin and a soft acid such as food grade sodium lactate. The saponin acts as a foaming agent providing surface tension reduction capable of loosening the biofilm. The solution is preferably applied by a mechanical device providing an efficient coating of the surface to be treated allowing a reduced amount of the lactate acid to be used allowing the acid to make contact with the bacteria while stripping away of the biofilm is made possible.
