Blackheads
Blackheads are comedones that are open at the surface of the skin. They are filled with excess oil and dead skin cells. It's not dirt that causes the comedone to turn black. The oil's reaction to air causes the black color. Blackheads can frequently be treated with over-the-counter medications.

toothbrush bristle. a bristle from a used toothbrush. It is covered in
dental plaque. Plaque consists of a film of bacteria embedded in a
glycoprotein matrix. Plaque is the main cause of tooth decay. The
bacteria feed on sugars in food, producing acid as a waste product. This
acid corrodes the teeth's enamel coating, resulting in dental caries. A
build-up of dental plaque can also lead to inflamed and infected gums.

why a cell phone has more bacteria than a toilet seat
Cellphones carry 10 times more bacteria than most toilet seats, so it shouldn't be surprising that a man in Uganda reportedly contracted Ebola after stealing one.
While toilets tend to get cleaned frequently, because people associate the bathroom with germs, cellphones and other commonly handled objects — like remote controls— are often left out of the cleaning routine.
Cellphones pick up germs all the time, Gerba said. "I see people talk on their phone on toilets."
However, the amount of germs on a phone isn't a problem — it’s the sharing of phones between people. Without sharing, each phone carries just one set of germs, and won't get its owner sick, Gerba said.
The problem with phones is that we're in constant contact with them, and they spend a lot of time in close proximity to our faces and mouths. And, because it's an electronic device, most people are hesitant about cleaning them.
