Tips to Clean the Thermos. Say Goodbye to the Odour!

Knowing how to clean the thermos is a useful effective piece of knowledge to know. Here are some methods to clean the customised thermos and an introduction to the cleaning utensils. These are some tips about how to remove the odour, tea stains and water stains from the thermos.
 

Clean Tips to remove odour inside the thermos

Vinegar and bicarbonate of soda

Vinegar and bicarbonate of soda is the best choice to remove odour. Because of their individual characteristics, they are used differently. Vinegar is acidic. It could neutralise the alkaline odour. Bicarbonate of soda could neutralise the acidic odour. You can put the thermos in the sink, pour water to immerse the water. Then add vinegar and bicarbonate of soda. They will generate bubbles. After the bubbles all disappear, rinse the thermos.
This tip is not suitable for the thermos that have silver coating on the inner bottle. Because the vinegar may corrode the inner silver coating. This may decrease the competence of anti-corrosion inside.
 

Rice Water

Pour the rice water into the thermos. Wait for some hours. The odour will be removed.
 

Tea leaf

Put tea bags in the thermos. Wait for almost half an hour. Then rinse the thermos twice or three times. Attention please! Close the thermos lid after the inside water is totally dried, or the water inside would cause odour.
 

Clean tips to remove tea stains and water stains

Lemon vinegar

Naturally fermented lemon vinegar doesn't have corrosion and is not bad for people and the environment.
Method:
Put 1 Litre hot water and 1 teaspoon lemon vinegar into the thermos. Wait for 1-2 hours. Then, use a brush to clean the inside.
Clean principle:
The tea stains and water stains have Calcium, Magnesium and Phosphate ions. The lemon vinegar can dissolve these minerals. So it’s easy to clean the thermos.

The lemon vinegar uses Acid-base neutralisation principle which are useful in five situations below:
1.  Dissolve the stain to be easily cleaned.
2. Stop bacteria reproduction
3. Remove the odour
4.  Neutralise the acidic and the alkaline to be easily cleaned
5. Stop the Metal rusting
 

Sodium percarbonate

Sodium percarbonate, the same as lemon vinegar, doesn't have corrosion and isn’t bad for people and the environment.

Method:
Put 1 Litre hot water and 1 teaspoon Sodium percarbonate into the thermos. Wait for 1-2 hours. Then, use a brush to clean the inside.
Clean principle:
When Sodium percarbonate dissolves in the water, it will decompose to Hydrogen peroxide and Soda. The Hydrogen peroxide generates bubbles and the Soda has strong cleaning, These two chemicals could quickly remove the stain and sterilise.
 

Bicarbonate of soda

Bicarbonate of soda is also known as sodium bicarbonate or baking soda. It tastes slightly salty and alkaline. It's non-toxic. Not bad for the people and the environment. Based on the content of baking soda, it is divided into three series: medicine, food and industry. We have to choose a food series to clean the thermos, making sure not to eat mistakely.

Method:
Put 200c.c marn water and 1 teaspoon baking soda. Close the lid and shake the thermos. Wait for 1-2 hours. Then brush the inside space.
Principle:
The majority of odour is due to the acidic chemicals. The baking soda is slightly alkaline. It could neutralise the acidic chemicals. And the particles of baking soda are so small that the particles could deeply clean those chemicals in the pores on the surface.
 

Clean utensils

When it comes to clean utensils, people may think of the melamine sponge. It’s very useful, but has its own drawbacks. Here are reasons that we don’t advise you to use melamine sponge to clean the thermos.

Melamine sponge is very popular in recent years. It doesn’t use any detergents. Just add some water, it can tidy up everything. The main ingredient in many abrasive cleaning sponges is melamine foam. Due to its great sound absorption, superior thermal insulation performance, and lightweight, it is also employed as the primary sound and thermal insulation material for bullet trains.
Due to the main ingredient is Melamine foam, it may generate the toxic Melamine when faced with high temperature, oil and the acidic. Its chemicals may leave on the tableware, it may generate the toxic when we eat the hot food.
