Do you want your thermos flask to be clean and odorless? SSPDaily has shared expert advice on effective methods of cleaning the item using common household ingredients.
Baking soda
Add 2-3 tablespoons of baking soda to the thermos flask, and then fill it with warm water. Let the mixture steep for a few hours and then scrub the inside with a bottle brush.
Lemon and salt solution
Cut a lemon into quarters, and then sprinkle the flesh with salt. Wipe the lemon on the inside of the thermos flask, focusing on areas with stains or a strong odor. The natural acidity of the citrus, combined with the abrasiveness of the salt, creates a powerful cleaning solution that effectively removes odors and stains.
Soaking in vinegar
Simply fill a thermos flask with a mixture of equal parts vinegar and water and leave it overnight. In the morning, rinse the item thoroughly with warm water. The acidic properties of the product break down food residues and remove stubborn odors, leaving it fresh and clean.
