How does the age of materials affect odor retention?

The age of materials plays a crucial role in how they retain odors, and the correct answer reflects this understanding. As materials age, they often undergo wear and degradation. This wear can create a porous surface or contribute to the buildup of particulates and residues that have the ability to absorb and hold odors more effectively. Additionally, older materials might have been exposed to various contaminants and environments over time, leading to increased odor retention.

In contrast, newer materials tend to have less exposure and fewer accumulated odors, making them less likely to retain unpleasant smells. The chemical composition of older materials can also change over time, which may enhance their ability to trap and hold onto specific odors. Thus, the potential for older materials to absorb and retain odors more significantly is a key concept in odor management and restoration techniques.
