Why Does My Thermos Smell Like Coffee?

Understanding the Science of Coffee Stains and Odors

When coffee spends a prolonged time in contact with a surface or a material, it often leaves behind stains and odor.

This is because coffee contains oils and acids that can be absorbed by the surface, creating a layer of stale coffee flavor or smell.

Factors that Affect the Smell of Coffee in a Thermos

The intensity of the coffee smell inside a thermos is influenced by several factors, including the material of the thermos, the length of time the coffee is kept inside, and how often the thermos is washed.

The heat retention ability of the thermos can also contribute to the smell if it is not washed frequently.

Types of Thermos Materials and Their Cleaning Requirements

Thermoses come in various materials such as stainless steel, plastic, glass, and ceramic, among others. Each material requires a specific cleaning procedure to maintain its quality.

For example, stainless steel thermoses can be cleaned with soap and water, while plastic ones may require special cleaners to prevent discoloration.

Here’s a general guideline for cleaning a thermos flask.
