To effectively remove stubborn coffee and tea stains from mugs, several reliable methods can restore their original appearance. The most commonly recommended and highly effective solution involves using baking soda. To use this method, sprinkle a small amount of baking soda into the bottom of the stained mug. Add just enough water to form a thick paste. Using a sponge or a soft cloth, scrub the stained areas with the paste. The mild abrasive quality of the baking soda will lift the stains without scratching the mug's surface. Once the stains are gone, simply rinse the mug thoroughly.
If the baking soda method is not sufficient or you prefer an alternative, other effective options are available. One such method involves using denture cleaning tablets. Fill the mug with hot water, drop in one tablet, and allow it to sit for at least an hour, or even overnight for tougher stains. The effervescent action of the tablet will break down the tannins that cause the staining. After soaking, pour out the solution and wash the mug with soap and water.
Another proven cleaning agent for this purpose is Bar Keepers Friend. This product is a mild abrasive cleanser that is well-suited for removing tough stains from ceramic and other surfaces. Apply a small amount to a damp sponge and gently scrub the interior of the mug until the stains are removed, then rinse completely. Each of these methods provides a straightforward and effective way to deal with accumulated coffee stains.
