Cleaning a water thermos lid requires a little more work than most other methods, but the level of effort is well worth the results. If you are having trouble with hard-to-remove stains or build-up of dirt on your lid, try vinegar, lemon or other substances.

Methods to Clean Water Thermos Lid

1. Using Mineral Water

Using mineral water is one of the most common ways to remove hard-to-remove stains or build-up on your water thermos lid. After washing the lid with water, use a cloth to rub gently in a circular motion to wipe off the dirty layer. The mineral water will soak up all of the dirt and help you remove it easily. You can also use lemon peels or baking soda if you wish.

2. Using Lemon Juice

Lemon juice is another great option to clean your water thermos lid. Before cleaning, wash your lid with warm water and dish soap. Afterward, grab some lemon juice and rinse it off to remove any buildup or stains on the surface. Again, you can also use baking soda or baking powder to wipe off any remaining traces of dirt.

3. Using Baking Soda

Baking soda is another option that you can use when removing hard-to-remove stains or build-up on your water thermos lid. Mix baking soda with warm water to make a paste, and scrub the lid until the baking soda has cleared off all of the dirt. To keep it smelling fresh, sprinkle some lemon or orange slices over the top of your lid.

4. Using Dish Detergent

One last option for cleaning your water thermos is to use dish detergent. Mix water and dish detergent to make a paste. Rub the paste on your lid with your fingers, and then work it with your nails to remove any tough dirt or grime. Finish off with soap and warm water to make sure that all of the dirt is gone.

How to Clean Stains on Water Thermos Lid

Cleaning stains on the lid is another important process that you must know how to do. You can easily remove stains from your lid by rubbing it with lemon juice, vinegar, or salt. Also, be sure to use a cloth when rubbing to avoid damaging the surface of your lid. Cleaning different types of stains is a tough task but you must consider each stain individually before trying to remove it.

1. Spot Stains

Spot stains are the most common types of stains that you might have on your water thermos lid. There are two main spots on the entire thermos; inside the cup and inside the lid. If you have a spot stain on the lid, use vinegar or salt.

2. Rust Spots

Rust can be another common stain that you might find if you use water from the tap. Water from the tap contains minerals and can cause rust deposits to form on your lid. To clean rust spots, use lemon extracts.

3. Yellowing Stains

Another common stain that you might find is yellowing stains, which usually look like a brownish-yellow discoloration. If you have this kind of stain, use salt or vinegar to clean it.

4. Coffee Stains

Another type of stain that is common is a coffee stain. Coffee is a common liquid that you will find inside your thermos, and the stains from this liquid can be difficult to remove. If you have coffee stains, use vinegar to remove them.

How Can We Elongate the Life of a Thermos Lid? 

Although the design of thermos lids is pretty simple, their performance can be affected by both external and internal factors. 

The first external factor that affects thermos lid performance is temperature. If the temperature is too high or too low, it can damage the seal on your lid or even produce a disoriented shape.

The second external factor that can affect thermos lid performance is humidity. Extreme low levels of humidity will disable your lid from its sealing capacity, making it difficult to keep beverages hot for a long period of time.

The last external factor that can affect your thermos lid is the frequency of use. Each time you open the lid, you expose the liner to dust particles, dirt, and bacteria which can compromise its performance ability. The best way to keep the lid functioning for a long period of time is to keep it clean on a regular basis.

Why is a Lid Important? 

A hot beverage kept inside a thermos will stay hot for much longer than if that same beverage is kept in a regular container. The lid functions as a barrier against the effects of temperature and humidity, allowing the beverage to stay hot or cold for long periods of time. Also, the lid prevents external elements from damaging the insides of your thermos, which can cause the product to malfunction.
