Cell phones are 146% dirtier than the minimum hygiene standard of 250. Although still failing the minimum standard of cleanliness, the average card is 38.4% cleaner than your phone. The only dollar bill to pass the minimum standard of cleanliness was the $50 bill.
Your cell phone is dirtier than you think. From home, to work, to the coffee shop around the corner, your phone picks up germs everywhere it goes. In fact, cell phones carry 10 times more bacteria than most toilet seats.
Sponges and cloths: a feast in the kitchen
But in reality, these are the household items which hold the most bacteria according to a study by Scientific Reports.
Banknotes recovered from hospitals may be highly contaminated by Staphylococcus aureus. Salmonella species, Escherichia coli and S. aureus are commonly isolated from banknotes from food outlets.
Many people believe that the bathroom is the dirtiest thing they regularly come into contact with; however, a cell phone can house up to 10 times more bacteria than a toilet seat.

Think the toilet is the dirtiest spot in the house? You'd be wrong. "There's more fecal bacteria in your kitchen sink than there is in a toilet after you flush it," said microbiologist Charles Gerba, known as "Dr. Germ."
But those greenbacks in your wallet are hiding far more than cocaine and the flu. They're teeming with life. Each dollar bill carries about 3,000 types of bacteria on its surface, scientists have found. Most are harmless.
“From the smell of the paper they are made of to the scent of fingerprints or ink.” The olfactory pyramid of this 'scent of money' starts with the olfactory notes of a banknote that has just left the Mint “and then moves on to more 'iridescent' and woody notes reminiscent of the smell of old banknotes.”
The bacterial presence on coins appears to be far more transient compared to their presence on banknotes. The bacterial microbiome associated with human hands survives poorly on coins, which appears to be due to a direct toxic influence from the coins on the bacteria.
The cleanest part typically, if not overcome with disease, are the air sacs (alveoli) in your lungs. It's a sterile environment. A vast majority of the human body have bacteria as part of the normal human flora. The mouth being the dirtiest part of the body housing the most harmful bacteria.
Paper money can reportedly carry more germs than a household toilet. And bills are a hospitable environment for gross microbes: viruses and bacteria can live on most surfaces for about 48 hours, but paper money can reportedly transport a live flu virus for up to 17 days. It's enough to make you switch to credit.
Kitchen. The kitchen is one of the busiest rooms in most homes and also the dirtiest. All of the elements that encourage bacteria to grow—heat, moisture, and food—are readily available.
According to Seattle Times journalist Bobby Caina Calvan, your phone is covered in germs: 25,127 bacteria per square inch, to be precise. This makes cell phones one of the dirtiest objects we come in contact with every day.
The average human hand houses 150 different kinds of bacteria. There are typically between 10,000 and 10 million bacteria on each of your hands. Most germs can survive on your hands for three hours. Besides coughing and sneezing, door handles are the most likely way that cold viruses spread.
Carpeting With 200,000 bacteria per square inch on average, an uncleaned carpet is 4000 times dirtier than a toilet seat.
Researchers tested the effects of various metals on human skin and found that what smells is not the metal, but the rapid interaction of skin oils with iron, copper and brass. The chemical reaction causes new, strongly scented gaseous compounds to form.
Making the Money
After paper money is designed, the design is sent to the Bureau of Engraving and Printing to be engraved onto a plate. The single plate is then reproduced many times onto a much larger plate that can print multiple bills at once. The plate is covered with ink and then pressed onto the paper.
But there's one thing we're a little less crazy about: that smell. Yeah, vinegar can be seriously pungent, and even if the smell does dissipate over time (which it totally, totally does), we very much understand that you might not have the time to wait, or might just not want to.
The color change of copper/green to black on the 100 in the lower right corner will help you verify an authentic $100 bill. A fake bill will not turn to black when you tilt the bill. It will stay copper/green.
You may have discovered from experience that paper money will hold up through an accidental trip through the laundry. Dollar bills are constructed mostly of cotton and durable cellulose fibers, meaning that they can safely be cleaned in a washing machine under the right conditions.
On July 14, 1969, the Department of the Treasury and the Federal Reserve System announced that currency notes in denominations of $500, $1,000, $5,000, and $10,000 would be discontinued immediately due to lack of use. Although they were issued until 1969, they were last printed in 1945.
You might imagine that it's the filthiest thing in your bathroom, and while you're not far off, there is actually something in most bathrooms that is even grosser. A new (admittedly small-scale) study performed by SafeHome suggests that your shower is actually dirtier than your toilet in terms of overall germ count.
Drews says that the bathroom and kitchen are the most germ-infested areas, in part because they include many of the frequently touched surfaces that can be loaded with germs. “There are less obvious things to think about like high-touch items, handheld electronics and, yes, your smartphone,” adds Dr.
The simple answer is YES. Shower water contains chlorine, bacteria, dissolved minerals, as well as, heavy metal. Depending on where you are located, the levels of chlorinated or contaminated water may vary.
