5 Easy Tricks To Get Rid Of Ex-Coffee Nodes

JAKARTA - Coffee often leaves stains on the cup because it contains a compound called tannin, a type of polyphenol that is naturally found in coffee beans. When the coffee is brewed, tannin can stick to the surface of the cup. This causes a brown stain that is difficult to remove in the cup.

Prevention is the best step. To prevent the stain before it appears, immediately rinse the cup after it is used so that the stain does not stick. However, another factor that exacerbates the stain is the coffee temperature.
