Remove Coffee Stains From Mugs
Nothing’s worse than picking up your favorite mug, only to realize there are gross coffee stains caked to the sides. No one wants to drink coffee out of a dirty mug, even if it’s hygienic. But you can use hydrogen peroxide to remove coffee stains from your favorite mugs and coffee cups. Let the hydrogen peroxide sit until the stains dissolve. Use half a cup of hydrogen peroxide and two tablespoons of baking soda in a mug filled with water. Let it sit for about 30 minutes so it works to its full potential, and clean the mug afterward. Those annoying coffee stains will be gone (Ecococoon).
