Pseudomonas aeruginosa biofilm on a surface is eradicated or at least reduced using a microbiocidally effective amount of at least one of the following bromine-based microbiocides: i) an alkali or alkaline earth metal bromide salt or zinc bromide activated by a water-soluble alkali or alkaline earth metal hypochlorite, ii) a water-soluble N,N'-bromochloro-5,5-dialkylhydantoin, and/or iii) a water-soluble active bromine product formed by mixing (a) bromine, bromine chloride, a mixture of bromine chloride and bromine or a combination of bromine and chlorine in which the molar amount of chlorine does not exceed the molar amount of bromine, and (b) a water-soluble source of sulfamate anion, in (c) an aqueous medium, which aqueous medium is adjusted to a pH of at least 12 either during or after such mixing.
