- Staining: Persistent staining that cannot be removed through cleaning can indicate that the clay’s surface is compromised and may be porous, making it more susceptible to contamination.
- Odor Retention: If a clay item consistently retains odors, even after thorough cleaning, it may indicate that it has absorbed food particles and is no longer suitable for use.
- Changes in Texture: A change in texture, such as a rough or uneven surface, can be a sign of wear and tear and can indicate that the clay’s integrity is compromised.
- Frequency of Use and Replacement: The frequency of use will affect the lifespan of a clay item. Regularly used items may need to be replaced more frequently than those used less often. Consider replacing items every 1-2 years, or sooner if any signs of damage are observed.
