Coffee is one of the essential beverages worldwide. It has a great taste that is satisfying, stimulating, and popular. But some people are not happy with the smell of coffee in their thermos. Some of the ways in which we can remove the smell are using vinegar, salt and other essentials. Here are some tips on how you can remove the coffee smell from your thermos without much effort.
Methods to Remove the Coffee Smell from the Thermos
Method 1. Vinegar and Baking Soda
1. Find some vinegar in your kitchen cupboard.
2. Mix 1/4 cup vinegar in the cup of water.
3. Then, mix one teaspoon of baking soda in a cup of water.
4. After you mixed well, put it in your thermos for about 3-5 minutes or until the smell is gone. Some individuals prefer soaking it overnight.
5. Put it in direct sunlight for a few minutes and then dry the flask with a dish cloth.
6. After it is dried, wash it with soap and clean water to ensure your thermos is 100% clean and there is no smell.
7. Let the thermos dry up in sunlight for about 2 hours.
8. If you don’t have baking soda, you can replace it with vinegar too. Still, vinegar would be better because baking soda may leave some white film in your thermos cup after the process.
9. After finalizing these processes, you will eventually have a clear and odor-free thermos at your disposal.
10. Clean and dry the cup with a dish cloth to remove any remaining smell of vinegar or baking soda.
Method 2. Dishwasher Powder
1. Get some dishwasher cleaning powder (any dishwasher powder will do)
2. Put 1-2 spoonfuls of powder in the thermos.
3. Then fill the rest of the space with water (don’t just fill the mug with water because it may leave some smell behind after cleaning).
4. Close the thermos and shake for 3 to 4 minutes.
5. Let it sit for 10 minutes so that all the powder can work on removing the coffee smell inside your coffee mug.
6. After 10 minutes, wash the thermos with soap and clean water to ensure it is 100% clean.
7. Put the thermos in direct sunlight so that all the leftover residue can be dried away by natural sunlight.
Method 3. Salt and Ice
1. For starters, obtain some salt and ice.
2. Put 1/4 cup of salt in the thermos cup and 1/4 cup of ice in it. (ensure you don’t fill the thermos with too much ice because if you do, then the ice would expand and may crack your thermos eventually.)
3. Put salt and ice in your thermos and close it.
4. Shake for about 8 minutes (don’t shake too hard as it can lead to damage).
5. After 8 minutes, open it up and shake again for another 2 minutes for better mixing.
6. After two hours, wash the thermos with soap and clean water to remove the remaining residue.
7. Then let it dry out in sunlight for about 2 hours (direct sunlight).
8. Now, your thermos would be 100% clean because there would be no smell left behind from any of the two methods.
9. Dry up the cup with a dish cloth to ensure all remaining odor is removed from your thermos after drying out in sunlight for a while.
10. This will eventually solve your odor issue.
Now, you know how to remove the coffee smell from a thermos. You can try any of these methods, which will also help keep rust and other contaminants away from the thermos, ensuring longevity and usefulness.
Frequently Asked Questions
Q. Why do people get the coffee smell in a thermos?

Q. What can I do if I have a thermos that smells really bad?
A. There are several things you can do to get rid of coffee stains from your thermos, but the most effective one would be to use vinegar and baking soda or salt-based cleaners. However, commercial cleaners are not preferred for thermoses.
