What should I do after buying a new thermos

Most newly purchased thermos have a certain odor, such as plastic cups having a plastic smell, paper cups having a wooden smell, and stainless steel cups having a metallic smell. This has caused a lot of trouble for many people, so how can we eliminate the odor in the cup?

According to industry introduction, the material of insulated cups is generally divided into PC PP、 Stainless steel and other insulation cup materials themselves have an odor, but some manufacturers will treat the odor of the cup to reduce or completely eliminate it. When we buy a thermos with an odor, we can use the following methods to remove the odor from the newly purchased thermos.

Wash with vinegar

For the first use, to ensure cleanliness, 1-2 drops of vinegar can be diluted in warm water and poured into a cup. Keep the cup lid open for 30 minutes, then clean with a soft cloth.

The principle of pouring vinegar to clean stainless steel insulated cups is mainly related to the acidic components in vinegar. Vinegar contains approximately 4-8% concentration of acetic acid, which can help dissolve stains, mineral deposits (such as scale), bacteria, and odors that may adhere to the surface of stainless steel.

Specifically, edible vinegar has several main functions, including removing scale and mineral deposits, removing odors, cleaning, and disinfecting. If stainless steel insulated cups are frequently used with water or beverages, it is easy to form scale or mineral deposits on the inner wall of the cup, especially in hard water areas.

The acetic acid in vinegar can effectively dissolve these mineral deposits, making them easier to rinse off. The acidic component of edible vinegar has a certain disinfection and odor removal effect, which can help remove the possible odors inside the thermos cup, such as residual or metallic flavors of the beverage. And acetic acid itself has a certain antibacterial effect, which can kill some common bacteria and fungi, helping to keep the thermos clean and hygienic.

Maintain ventilation

At this time, it is necessary to separate the cup lid from the cup body, open it, and place it in a ventilated position for 1-2 days, which can basically remove the odor.

The principle of this method mainly relies on the circulation of air and the emission of volatile substances. When there is an odor in an object or space, it is usually due to the presence of volatile organic compounds or other molecules in the air. These odor molecules can adhere to the surface of objects or dissolve in the air.

By opening windows or using fans to increase air flow, indoor air users can accelerate the exchange of external air. As the air flows, indoor gases containing odors will be carried away, reducing the concentration of odors in the space.

Some odors, such as moldy smell, are often related to high humidity environments. Ventilation can help with air flow, thereby reducing humidity in the space, minimizing the growth of microorganisms such as mold, and removing odors related to humidity. Some odor molecules may react with oxygen or other substances in space to produce fearless or more volatile compounds. Ventilation can promote these reactions, thereby accelerating their disappearance.

Other methods to eliminate odors in thermos cups

After bending the head with wire, hook out the silicone ring, carefully clean and wipe it with medical alcohol, and expose it to sunlight for more than two hours to reduce the smell of silicone.

The principle of doing so is that medical alcohol has solubility, which can dissolve some volatile organic compounds that may exist on the surface of silicone gel, which is one of the main reasons for the odor of silicone gel. Can some residual chemical substances on the surface be removed, such as plastic additives, stabilizers, or cleaning agents used in the production process? These substances may not be completely removed, causing silicone to have an odor.

Expose the silicone ring under direct sunlight, as ultraviolet radiation is the most critical factor. Ultraviolet radiation can damage the structure of some volatile organic compounds and microorganisms, especially chemical residues that may exist in some plastic or rubber products. UV exposure can not only help decompose and degrade these organic compounds, but also help evaporate residual odor molecules on the surface of silicone, thereby reducing odors.

Under the influence of sunlight, ultraviolet rays may also trigger some oxidation reactions, which help to decompose or transform certain odor molecules in silica gel, making it odorless or less noticeable.

Based on Doyoung‘s over ten years of industry experience, we have summarized that the above can effectively eliminate odors in stainless steel insulated cups. It is a common phenomenon for newly purchased stainless steel insulated cups to have a strange smell, and it can be understood as a normal phenomenon. Mainly caused by residues or material characteristics during production, packaging, transportation, etc., this phenomenon is normal and temporary. By adopting appropriate cleaning methods, the odor will gradually disappear.
