Should you flush with toilet lid up or down? Study says it doesn’t matter
Should you flush with toilet lid up or down? Study says it doesn’t matter
https://www.ajicjournal.org/article/S0196-6553(23)00820-9/fulltextFile this one under "Studies We Wish Had Let Us Remain Ignorant." Scientists at the University of Arizona decided to investigate whether closing the toilet lid before flushing reduces cross-contamination of bathroom surfaces by airborne bacterial and viral particles via "toilet plumes." The bad news is that putting a lid on it doesn't result in any substantial reduction in contamination, according to their recent paper published in the American Journal of Infection Control. The good news: Adding a disinfectant to the toilet bowl before flushing and using disinfectant dispensers in the tank significantly reduce cross-contamination.
