Many people enjoy a cup of nicely brewed coffee or tea. Most of us always look forward to their next mug, but we all dread taking it from a cup with stains. Serving visitors in tea stained cups is a sign of a poor host too. In most cases, contrary to what many people assume, coffee and tea stains on cups are not as a result of poor hygiene. Even mugs that are thoroughly cleaned daily with a good dishwashing agent or soap can easily stain, and may need special cleaning once in a while to remove stains. These stains appear as brown rings around the top and bottom of your cups.
