While most of us like a good cup of coffee to get us going in the morning, coffee stains on your Tervis tumbler can be unsightly and disappointing.
Coffee tends to stain if it is allowed to sit in your tumbler, but running your tumbler through the dishwasher won’t always remove the coffee stains.
Luckily, you don’t have to worry any longer about coffee stains discoloring your tumbler.
We’ve done the research, and removing coffee stains from your Tervis tumbler is easy if you use a couple of everyday household items and follow the steps below.
What You’ll Need
You will need a few essential household items to clean coffee stains out of your Tervis tumbler.
Now that you have everything you need read on to learn how to clean coffee stains from your Tervis Tumbler.
1. Pour a Little Baking Soda into your Tervis Tumbler
If you are in the habit of leaving undrunk coffee in your Tervis tumbler, you have probably noticed some coffee stains inside of it.
Once you see that you have coffee stains, rinse and dry your tumbler to remove any lingering coffee, and then pour two tablespoons of baking soda inside.
Pro tip: Baking soda is a joint whitening agent and stain remover and can often be used to help get coffee stains out of various surfaces around your house.
You can further heighten the effectiveness of baking soda by adding a few drops of lemon juice or a little vinegar.
Both lemon and vinegar are acidic, so they react with the baking soda and heighten their stain-fighting powers.
2. Add Enough Vinegar to Create a Paste
Once you have poured your baking soda into the bottom of your Tervis tumbler, add a couple of tablespoons of white distilled vinegar.
Your goal is to add enough vinegar so that the baking soda becomes a paste.
You don’t want it too wet, though, or the mixture will be difficult to work with.
A couple of tablespoons of vinegar should be enough to bring the paste together.
If it’s not, simply add vinegar until you create the paste.
3. Rub Paste onto the Coffee Stains with a Microfiber Cloth
Now that you have made your paste out of baking soda and vinegar, take a fresh microfiber cleaning cloth and rub the paste on the coffee stains inside your Tervis tumbler.
I recommend these MR.SIGA Microfiber Cleaning Cloths that I found on Amazon.
They work really well on just about any cleaning project plus they get excellent reviews on Amazon.
Remember, baking soda can be abrasive, so rub gently to avoid the possibility of scratching your tumbler.
Scratches provide safe havens for stains to settle into your tumbler, making it even more challenging to get them out in the future.
Important Note: The image above shows a scrub brush being used.
That’s fine to use on a regular mug, (like the video) but please make sure you use a microfiber cleaning cloth for your Tervis Tumbler.
4. Rinse and Repeat if Necessary
Finally, rinse your tumbler out with lots of fresh water.
You can also wash your tumbler at this point with your dish soap to remove any traces of the baking soda.
If this process has not entirely removed the coffee stains, you can repeat these steps to remove the coffee stains further until you are delighted with the cleanliness of your tumbler.

Tervis tumblers are designed to be dishwasher safe, so most of your cleaning needs can be satisfied by running your tumbler through the wash cycle on your dishwasher.

How do you get rid of the coffee smell in your Tervis tumbler?
Sometimes, the coffee stains in your Tervis tumbler can cause your entire tumbler to reek of old coffee.
While removing the stains per the above instructions will help to remove the odor, it may not eradicate it because plastic tends to absorb strong odors when exposed for long periods.
To remove the coffee smell from your tumbler, mix 3 cups of warm water and 1 cup of baking soda.
Submerge your Tervis tumbler in this solution for 8 hours—overnight will work very well.
Baking soda is a natural and effective odor eliminator, so it should remove the coffee smell from your tumbler.
Then, rinse and dry your tumbler thoroughly, and check it for any lingering smell.
If there is a faint lingering scent, moisten a paper towel with distilled white vinegar.
Use the paper towel to wipe out your Tervis tumbler.
Vinegar is also a natural odor eliminator, so if the baking soda does not entirely remove the coffee smell, the vinegar will finish the process.
After you have wiped out your tumbler with vinegar, wash it with dish soap and water to remove the vinegar.
Doing this will not only prevent the vinegar from seasoning your next beverage; it will also remove any traces of vinegar smell from your tumbler.
After you have washed your tumbler, rinse it out several times and allow it to dry completely before using it again.
