An account is presented of a survey which was undertaken to investigate the nature and extent of the microbial flora of in-service ceramic tile surfaces and their grout joints. A list of taxa isolated is presented. The effect upon the resident flora of cleansing these surfaces with 1% hypochlorite is fully documented. A series of laboratory experiments are described in which selected tile surfaces and grout jointing compounds were deliberately infected with a flora representative of that encountered in the field. Results are presented which show the effect of cleansing with 1% hypochlorite upon this infected flora. The results of the investigations show that the wide range of natural flora of ceramic surfaces and the deliberately infected flora can be reduced by washing with 1% hypochlorite.
