How to Make Your Thermos Tumbler Sparkling Clean

Drinking water is a wonderful thing! But drinking mold and mildew is certainly not a good idea. There is no way for us to tell whether a thermos tumbler is infected with germs just by looking at its exterior. Moreover, even the finest stainless steel tumbler needs some strategies to keep them functioning properly and give you the best-tasting drink for years to come! If you want to keep your stainless steel tumbler in the best possible condition on a daily basis, as well as when you need a more thorough clean, let’s dive into this article.

1. Why should we clean our tumbler regularly?

Warmth and humidity inside a tumbler is an ideal environment for bacteria to thrive. But why does this phenomenon happen? As you go about everyday activities, some bacteria will pull on your hands. Consequently, if you don’t wash your hands often, the germ count may increase. And when you open the tumbler’s lid to take a drink or to refill it, these germs will be transmitted from your hands or your mouth to the tumbler. Furthermore, a tumbler does not generate bad smells unless food or tiny residues remain inside.

According to environmental tests conducted by Treadmill Review, a typical reusable water bottle has over 300,000 colony-forming units (CFUs) per square centimeter. That is nearly six times as much bacteria as you’d find in a pet bowl. What an unbelievable number!

2. How often should you clean your tumbler?

You may believe that cleaning your reusable tumbler once a week, or perhaps once a month, is sufficient. After all, it seems to be spotless, and the only thing you do is to fill your beverage in it. But how frequently should you clean something that you drink on a daily basis? According to experts, it is essential to wash the tumbler immediately after each use in order to reduce the amount of staining and bacteria buildup over time. Bacteria are more prone to develop in tumblers containing beverages such as coffee, smoothies, and alcohol. In such case, cleaning your thermos tumbler on a regular basis will keep it in excellent condition and safe for your health.

3. How to clean and deodorize separated parts of a tumbler

Even the finest stainless steel tumbler needs a little TLC to keep them functioning smoothly and giving you the best-tasting drink for years to come! If your tumbler has stains or an unpleasant odor or if you haven’t cleaned it in a while, now is the time. The following are a few simple methods for cleaning deep water bottles:

3.1. How to clean tumbler

Use vinegar and hot water

• Step 1: Add ½ cup of white vinegar to your tumbler
• Step 2: Close the lid (make sure it’s on tight) and give a good shake
• Step 3: Top off the tumbler with hot water and let it sit for 30 minutes
• Step 4: Clean the built-up residue using a specialized bottle brush
• Step 5: After the surface is clean, pour out the mixture and rinse thoroughly with warm soapy water to remove all residues

Use baking soda and hot water

• Step 1: Add two tablespoonfuls of baking soda to the bottom of your tumbler with hot water
• Step 2: Set aside to let the foaming liquid froth up and begin its thorough exfoliating of the stains
• Step 3: When the initial foaming settles down, close the lid and shake vigorously to distribute the liquid all around the tumbler
• Step 4: Clean the built-up residue using a specialized bottle brush
• Step 5: Pour all the mixture out and rinse the tumbler thoroughly with warm soapy water

3.2. How to clean tumbler lid

When it comes to tumbler cleaning, completely disinfecting the lid requires a bit more time and attention to detail, especially in tiny surface areas like the corners and opening of the snap-in drinking features, where germs may build easily.

The components of your tumbler lid should be taken apart so that you can thoroughly clean each one and remove any buildup of debris between the seals. Once you’ve removed the slider drinking spout cover, you can pop off the rubber ring that forms a spill-proof seal around the lid’s outer perimeter. Each item should be cleaned with soapy water, and then dried before being reassembled.

3.3. A few notes to keep in mind

• Always bear in mind that coffee stains appear sooner if it is left in the tumbler for an extended period of time. You may avoid stains on your cup by drinking your coffee while it’s still hot.
• Bacteria grow in a moist environment. So the lid and tumbler must be allowed to air dry entirely, regardless of how you washed them. Place them upside-down on a drying rack or dish towel and leave the lid’s sliding, retractable drink spout open halfway to let air flow through the spaces between them.
• The temperature of the water should be around 70-80 degrees Celsius. It is necessary to check the material of the tumbler before cleaning with hot water to avoid overheating that may damage the tumbler.
• You should never use bleach to clean your tumbler. Bleach has a strong oxidizing chemical that degrades the chromium oxide in your travel tumbler, which is the component that makes your steel stainless. Instead, stick to vinegar and baking soda if you want to get a supercharged clean.

Stainless steel is a terrific material for coffee containers of all sizes and shapes, but every now and then you’ll come across a stain that no amount of washing will remove. Try these expert cleaning recommendations for your thermos, and you’ll have many years of pure-tasting, delicious beverages to take with you on all your journey!
