According to a recent study at Manchester University, there are more than ten million bacteria on your toothbrush more than your average toilet seat which has 50 bacteria per square inch, or average public lavatory floor which has two million bacteria per square inch. every time you flush the loo, an aerosol spray of tainted water is released with droplets able to land as far away as 10 feet. Researchers from the University of Alabama found that brushes stored in the bathroom are contaminated with faecal matter lingering in the bristles. One way to safeguard your toothbrush is to use a Steripod toothbrush protector.
