The present invention provides a composition for washing domestic animals, and in particular udders of domestic milking animals such as cows and sheep, comprising: a) an anolyte fraction obtained by electrolysis of a sodium chloride solution at a pH within the range of 6.0 -7.0, said anolyte fraction having an oxidation reduction potential (ORP) within the range of 450 -950 mV and b) an aqueous tenside preparation containing 1 -10 % (wt) chlorosulfonated and saponified paraffin oils, 0.1 -0.5 % (wt) 2-phenoxyethanol, and 0.005 - 0.1 % (wt) of at least one compound selected from the group of methyl paraben, ethyl paraben, propyl paraben, butyl paraben and isobutyl paraben wherein the anolyte fraction constitute 94 -99 % (wt) and the aqueous tenside preparation constitute the balance up to 100 % (wt) of the composition. The invention also provides methods of using the composition for washing domestic animals.
