Microbial contamination of bathrooms by aerosols generated by toilet flushing has been previously demonstrated. In this study, the impact of automatic bowl cleaners on aerosol generation was evaluated. Three toilet bowl cleaners which contained 2.5, 6.7 or 18.2% surfactant materials were evaluated. Results indicated that these cleaners significantly (p≤0.05) reduced the numbers of bacteria ejected from the bowl, and that the cleaner containing the greatest amount of surfactant was the most effective in aerosol reduction.
