Toothbrushes When you flush your toilet, it's true that the germs can go up to fifteen feet in the air and linger for over several hours! These germs land directly onto your toothbrush, especially if they're found in close proximity to your toilet. Kitchen Sponges Did you know that there are 10 million bacteria per square inch on your average kitchen sponge. These sponges can be 250,000 times dirtier than your toilet seat. Pillows Pillows may seem like an unlikely bacteria haven but they do in fact contain dust mites, skin cells, dead bugs, body secretions, and fungi which makes up for a third of the weight of your pillow. Bathtubs The drain in your bathtub contains 19,500 bacteria per square inch. The warm and moist environment is the perfect place for bacteria to thrive. The dirty water contaminates the entire tub, so it's not the ideal place to always clean yourself. Carpet Carpets have many hidden germs, there are 200,000 bacteria per square inch of your average home carpet! Yes, that's 4,000 times that of a toilet seat. Yikes.
