Insulated cups, as our daily drinking companions, often produce unpleasant odors due to prolonged use, causing headaches.
1. Unveiling the source of the odor in the thermos cup
The odor of thermos cups is usually caused by long-term storage of food or beverages and improper cleaning. Residual food and beverages can breed bacteria, mold, and spoil in insulated cups, resulting in unpleasant odors. Therefore, regular cleaning and disinfection of insulated cups are crucial.
2.10 efficient deodorization methods
(1) Hot water soaking method
Method: After thoroughly cleaning the thermos, pour in boiling water, cover it with a lid, and let it soak for at least half an hour. High temperature can effectively kill bacteria and promote the volatilization of odor molecules. Afterwards, pour out the hot water and rinse thoroughly with clean water.
(2) Lemon deodorization method
Method: Cut fresh lemon slices or squeeze lemon juice into a cup, add warm water (avoid using hot water to avoid damaging the vitamin C in the lemon), cover and shake a few times to allow the aroma of the lemon to fully penetrate. After standing for a period of time, pour out lemon water and rinse thoroughly with clean water.
Principle: The fresh aroma of lemon can effectively neutralize and absorb odors, while the citric acid in lemon can undergo acid-base neutralization reaction with odor substances to remove odors.
(3) Baking soda cleaning method
Method: Add an appropriate amount of baking soda and water to a thermos, gently wipe the cup wall and bottom with a soft cloth or sponge, especially the hard to reach gaps. Baking soda can decompose and adsorb odor molecules, while removing scale and stains. After cleaning, rinse thoroughly with clean water and air dry.
(4) Tea deodorization method
Method: Place dried tea leaves or soaked tea residue into a thermos, add a small amount of hot water, cover with a lid, and let it sit for a period of time. The aroma of tea will gradually penetrate and cover the original odor. Afterwards, pour out the tea and rinse thoroughly with clean water.
Principle: Tea polyphenols in tea have the ability to adsorb odors and effectively remove odors from thermos cups.
(5) White vinegar disinfection method
Method: Pour an appropriate amount of white vinegar and water (in a ratio of about 1:3) into a thermos, cover it with a lid, shake it evenly, and let the white vinegar fully contact the cup wall and bottom. After standing for a period of time, rinse repeatedly with clean water until there is no residual vinegar odor.
Principle: White vinegar has strong sterilization and disinfection abilities, as well as the ability to remove odors.
(6) Toothpaste Odor Removal Method
Method: Clean the thermos cup with toothpaste, especially the cup mouth and lid, which are prone to dirt and grime accumulation. Toothpaste can not only remove bad breath from the mouth, but also remove odors from thermos cups.
(7) Saltwater odor removal method
Method: Put salt into a cup, then add some water, cover with a lid and shake evenly. Let it stand for more than ten minutes before cleaning thoroughly. Saltwater has a bactericidal effect and can effectively remove odors.
(8) Milk deodorization method
Method: Pour half a cup of warm water into a thermos, then add a few spoonfuls of milk, shake gently for a few minutes, and pour out. The protein in milk can combine with odor substances to remove odors. Afterwards, rinse thoroughly with clean water.
(9) Orange peel/lemon peel odor removal method
Method: First, clean the cup with detergent, then put fresh orange peel or lemon peel into the cup, tighten the cup lid, and let it sit for about four hours. The aroma of orange peel and lemon peel can cover the original odor, then clean the cup thoroughly.
(10) Boiling water to remove odor method
Method: Put the thermos into boiling water and boil for 2-3 minutes, or use a disinfection cabinet for disinfection. This can not only kill most bacteria, but also effectively remove odors. Afterwards, rinse thoroughly with clean water.
