How to get the coffee smell out of a thermos?
To get the coffee smell out of the thermos, use baking soda and hot water. Baking Soda, chemically known as Sodium Bicarbonates, makes an excellent cleaning agent. There are cleaning agents that you already have at hand; vinegar, dishwasher powder, and salt.
Let us discuss some of the popular items and how they are used to get the smell out of a thermos:
Put a teaspoon of baking soda in the thermos, then fill it with water.
Leave the thermos for 30 minutes.
If the smell is too strong, leave the baking soda solution for longer. Otherwise, you could also repeat the process altogether.
Vinegar is an acid, therefore, makes a terrific cleaning agent.
You could also use heated water to get rid of the odor. Hot water helps to loosen up the aromatic compound and bacterial gunk that has accumulated inside the thermos.
You could soak it in overnight or for a few hours.
If you use equal parts of the vinegar and water, it will take lesser time to get rid of the coffee smell.
Use your dishwashing brush to scrub it up to loosen the lodged particles of coffee.
3. Dishwashing Powder
Using the dishwashing process is a comparatively convenient method compared to the rest. Here, all you need to do is add a teaspoon of dishwashing powder and add some hot water.
You can also clean your thermos in the dishwasher.
Give the thermos a good shake after you put the lid back on.
Now fill it to the top with some hot or warm water. Let the thermos sit for as long as you feel is necessary.
After you empty the thermos, be sure to give it a short but thorough scrub. Lastly, rinse the thermos repeatedly to get rid of the debris of the detergent.
4. Salt and Ice
Salt and ice work as an exfoliant to clean the inside of your mug. Salt is an antibacterial agent that does a thorough job of cleaning.
First, add ice cubes until a quarter of the thermos has filled up. Now before the ice melts, quickly add 2-3 tablespoons of salt.
Shake the thermos vigorously so that the ice and salt make thorough and harsh contact with the thermos walls. Even though salt is not a harsh chemical, but makes a good cleaning agent. After thorough shaking, rinse it with some water.
5. Baking soda and vinegar
You can pour a bit of baking soda into the acid solution in the thermos. The foaming chemical reaction will speed up the process for you.
Add 4 oz of vinegar and 1 tablespoon of baking soda. Vinegar is an acid, while baking soda is basic; they together form a neutral solution. As the two chemicals start to fizz, mix them up to get to every corner of the flask.
When the fizzing stops, the chemical reaction has stopped. Now fill up the thermos with hot water. Doing so helps to get rid of the chemical residues and any odor or microorganisms that may be left behind.
Leave the hot water in the thermos for about 10 minutes. Scrub the thermos and throw the water away. Repeat once or twice as necessary.
Use another acid
Instead of vinegar, you could use another acidic source. You can use a citric acid source such as lemon juice. You could even purchase citric acid and make it into a solution.
Use a denture tablet
Fill half of the thermos with hot water. Let the thermos soak for a few minutes and then add the denture tablet. Fizzing will start to occur as the tablet dissolves. Let the chemical reaction and work its magic for about half an hour in the uncovered flask. After the thermos has soaked, scrub the insides and then rinse.
A couple of steps you could take to keep the coffee smell to a minimum:
Rinse the thermos as soon as you get home. Frequently cleaning the thermos will prevent the buildup of the coffee compounds and prevent the lingering smell.
After you clean the thermos, wipe it dry and air it out.
You could choose to air dry the thermos but be sure that it is free of moisture before putting the lid on.
