Coffee and tea is a popular way to drink something warm and delicious. Some people even start their day with a hot cup of joe. But sometimes, we get lazy and leave coffee cups lying around the house, putting off the cleaning time until later, or simply not taking it out at all. Today I’m going to show you how to get rid of that stubborn coffee-smelling thermos in only four easy steps.

Why Does a Thermos Smell of Coffee?

Well, it is because of the inner coating or lining. The thermos is likely made from stainless steel, but the inside layer or lining gives it its unique ability to keep liquids warm for a prolonged period. The problem with this coating is that it tends to absorb coffee and tea odors over time. And since the layer cannot be washed away with water, all you have to do is soften or dissolve the smelly residues that have accumulated over the years. To do so:

  1. Take equal parts of vinegar and water (1:1)
  2. Adjust the ratio until you get a consistent mixture. You can also try using baking soda instead, but I prefer vinegar.
  3. Take the thermos and spray it with this vinegar solution (or use your spoon).
  4. Let it sit for about 8 hours, at which point the coating should be soft enough to come out quickly.
  5. Just look at how easy it is!

Now all you have to do is wash away the remaining dulling smell of the vinegar solution and treat your thermos like new! Happy cleaning! After that, you can put your favorite beverage in it and take it with you wherever you go.

How Long Can You Keep Coffee in a Thermos?

You may have now probably learned how to clean other thermoses as well. It’s a good idea to take care of it regularly, like every month or so. Regular cleaning should make the surface polished and smooth, and it can get rid of any dirt or residue left by food. Now let’s take a look at the question: How long does coffee keep in a thermos?

Many factors affect the durability of your thermoses, like how old it is, whether or not it was exposed to sunlight or not and how it is stored. Here are the general rules that can apply to all thermoses:

There are several things you can do to extend the life of your thermos for a longer time to ensure a more extended period of coldness and freshness for your food and drinks to keep right away after preparation:

  1. Add ice
  2. Rinse fruits and vegetables with cold water before use if they have been cut up or cooked in it.
  3. Store in the fridge (not in the freezer) to avoid condensation forming on the inner walls of your thermos.
  4. Rinse your thermos weekly with cold water and dry carefully with a soft cloth or paper towel, not terry cloth or other fabrics that might scratch the surface (and cause rusting).
  5. Make sure that any condensation is wiped off before heating up.
  6. Don’t heat hot food or liquids in your thermos, instead of warm it to body temperature. It also helps to prevent condensation from forming on the walls of your thermos. 7. Use an appropriate size. The thermos should be large enough to easily hold all the things you need to prepare the food.
  7. To keep your thermos clean, use a damp cloth and soap (do not use alcohol). Lightly and quickly wipe and rinse the thermos after usage to avoid corrosion and rusting.
  8. Avoid using cleaning solvents inside your thermos as they may ruin its inner appearance and damage it somehow.
