Clean a Toilet Bowl
This is a popular one. People have been saying for so long that Coke can clean toilet bowls, but has anyone ever actually tried it? I mean, Coca-Cola is black and can stain a white toilet bowl. So most people stick with bleach. However, this hack actually works. You simply let the Coke sit, and the acid will eventually remove the built-up dirt and will make your toilet white and shiny again.

Fun fact: Did you know Coca-Cola used to be free? It was originally a hit at the soda fountain, and in 1888, when Asa Griggs Candler took over, he handed out coupons for free Coke. People loved it so much that they came back for more as paying customers! It cost 5 cents a glass.
