Claims20
A biofilm deactivating composition comprising:
- at least one biocide, wherein the biocide is a fatty acid, anionic surfactant and/or quaternary ammonium compound;
- and
- a hydronium ion source, wherein the hydronium ion source is a strong acid comprising one or more of sulfuric acid, nitric acid, hydrochloric acid, phosphoric acid, hydrobromic acid, hydroiodic acid, or methane sulfonic acid,
- wherein a use solution of the composition at a concentration of at least about 100 ppm provides at least a 5-log reduction.
