Office coffee mug could be carrying colonies of germs, making it a home for bacteria, says expert.
People rarely take their office coffee mug home for washing and many times they scrub it at the office with sponges and brushes that have been used by everyone.
In fact, Charles Gerba, Ph.D., a professor of environmental microbiology at the University of Arizona, told Mens Health that twenty percent of mugs carry fecal bacteria, according to the Huffington Post.
So, cleaning your office cup is very important, said Gerba.
He suggests bringing your favorite cup home daily to be washed in a dishwasher on the hottest temperature possible.
If you don't have a dishwasher, then first fill the cup with hot water and put a teaspoon of baking soda in it, letting it sit overnight. And then, finally wash it in hot water as you normally would, said one user on Mamapedia.
