Precautions For The First Use Of Double-walled Stainless Steel Insulated Wine Glasses

Before using the double-walled stainless steel insulated wine glass for the first time, you need to pay attention to the following points:

Cleaning the inside: First, the inside of the thermos cup should be thoroughly cleaned to remove dust or chemicals that may remain during the manufacturing process. It can be cleaned with a mild detergent and a soft cloth, avoiding harsh brushes or scrubs that can scratch the liner or shell.

Boiling water: After cleaning, blanch the inside of the thermos cup with boiling water, the purpose of this step is to remove bacteria and odors on the inner wall. Fill the cleaned thermos cup with boiling water, close the lid, wait for a few minutes before pouring the water out, being careful not to overheat the boiling water to avoid burning yourself.

Preheat treatment: Pour hot water into a thermos cup, close the lid tightly, shake it lightly a few times, and let it sit for a while. This process allows the material inside the thermos cup to fully expand and fill the tiny voids, thus improving the heat preservation effect. At the same time, the preheat treatment can also remove the odor that may exist inside the thermos cup.

Avoid overfilling: When tightening the lid of the cup, do not use too much force, so as not to cause the screw of the cup to fail and affect the carrying. At the same time, do not overfill the water to avoid boiling water spilling and scalding when tightening the lid of the cup.

Avoid collision and fall: Avoid collision and fall during the use of the thermos cup, so as not to damage the inner tank or shell and affect the insulation effect. Keep it clean: The thermos cup should be cleaned regularly to avoid stains such as limescale and tea stains from sticking to the inner tank and affecting the insulation effect.

Correct use: Avoid exposing the thermos cup to sunlight or high temperature for a long time, so as not to affect the heat preservation effect. At the same time, it is also necessary to avoid placing the thermos cup upside down or horizontally to avoid hot water spilling out of the lid. Sealed storage: When the thermos cup is not in use, it should be closed tightly and stored in a dry and ventilated place. Avoid placing the thermos cup in a humid or high temperature environment, so as not to affect the insulation effect and service life.
