Please don’t sit on public tiolets, I’m not absolutely sure about Hep B, so please check into that and if not how about those critters lice? It could be on the toilet. Your reply has disturbed me. I am a mother who is constantly telling my child and others ‘just by looking at it with the naked eye doesn’t mean the toilet is clean.’ The demo I use is if you urine all over the toilet and wipe it off using lots of toilet paper or paper towels the toilet shines, but it isn’t disinfected. Now if you put lots and lots of toilet paper and/or paper towels on the toilet, leave it and sit. Being an African American woman with a second grader I would admit I sit on public toilets. too. Besides who says the janitors do there job.
