    Hi Maddy, try putting in a bit of vinegar and add some baking soda. Top it up with really hot water and let it sit for a bit.

    Then take a bottle brush to the inside, should make it easier to get the stains out.

    You can try using a denture cleaning tablet and letting it soak for a while. You can also use warm water, baking soda, and a bit of vinegar and let that soak. Cleaning it with a textured kitchen sponge will also help but you may have to scrub a bit. I would NOT use anything any more abrasive than a textured kitchen sponge to clean it as it would get scratched.

    Step 1

    Pour 2 tablespoons of baking soda into the empty coffee mug.

    Step 2

    Pour 1/4 cup of distilled white vinegar or apple cider vinegar into the stainless steel mug also.

    Step 3

    Watch the two ingredients foam when combined. This deodorizes and disinfects the mug.

    Twist the lid onto the stainless mug, and shake for 5 seconds.

    Step 5

    Pour out the mixture and rinse the mug with hot water.

    Step 6

    Wipe the interior of the coffee mug with a wet cloth, and rinse the mug again with hot water.

    Hi Maddy. I'm Cindy. Sprinkle a little baking soda into the mug. Add just enough hot water to make a paste. Scrub with a non-abrasive scrubbie. The gentle abrasion of the baking soda will get rid of the stains. Then rinse and wash the mug with clean water. Good luck Maddy and happy holidays.

    I would simply mix a bleach solution and let it sit for 30 minutes.
