Toilet seats aren’t as dirty as we thought.
Surprisingly, toilet seats themselves aren’t the dirtiest places in a restroom. A microbiologist named Charles Gerba believes that the most frequently touched surfaces pose the highest threat. For example, people are more likely to touch doorknobs, sinks, and toilet paper rolls with their unwashed hands, putting additional microbes on them. As for the toilets, they rarely come in direct contact with our skin or any other part of our body and many people also wipe them off with a napkin before using them.
