How to Remove Coffee Stains From Travel Mugs

A travel mug is a convenient and cost-effective way make coffee just how you like it and take it with you when you leave the house. Unfortunately, it's all too easy to forget about your travel mug and leave it on your desk at work or under the seat of your car, where leftover coffee stains the mug. Once your travel mug is stained, soap and water isn't going to clean it.

Coffee stains are stubborn.
  1. Make a paste of 3 parts baking soda and 1 part water. If your travel mug has some odor in addition to the visible stain, let the baking soda paste sit in the bottom of the mug for at least 30 minutes. If you can, leave the paste in the mug overnight.

  2. Use a damp sponge to work the baking soda paste against the coffee stain.

  3. Rinse the travel mug with clean water and check to see if the stain is completely gone.

  4. If any stain remains, add a small amount of undiluted white vinegar--just enough to cover the bottom of the travel mug. Wipe the vinegar around the bottom of the mug.

  5. Rinse the travel mug thoroughly and allow it to air dry.
