Iodophors work by releasing free iodine, which is the active ingredient that kills microorganisms. If the solution is too concentrated, there may not be enough free iodine present to effectively kill all the microbes. Therefore, proper dilution is necessary to ensure that there is enough free iodine for effective microbial killing.
