The Science Behind Mold on Leather

Understanding the science behind mold growth can help you prevent and tackle it more effectively. Mold is a type of fungus that thrives in moist environments. Leather, being porous, can absorb moisture from the air, providing an ideal environment for mold spores to settle and grow. These spores are ubiquitous in the environment, meaning that mold can grow on leather almost anywhere if the conditions are right.

Mold spores are microscopic and can spread quickly once they find a suitable environment. They feed on organic materials, which is why leather, composed of animal hide, is particularly susceptible. By understanding these basic principles, you can take more informed steps to protect your leather items.

Handling Mold on Different Types of Leather

Leather comes in various types, each requiring specific care methods. Here’s how to handle mold on different leather types:

Aniline Leather:

Aniline leather is dyed with soluble dyes, which retain the natural surface, including the pores. This type of leather is more susceptible to mold because of its high porosity. Use gentle cleaning methods, avoiding excessive moisture. Conditioning is crucial to maintain its natural beauty.

Semi-Aniline Leather:

Semi-aniline leather has a light protective coating, making it slightly more resistant to stains and mold. You can use the same cleaning methods as for aniline leather but with a bit more confidence in its durability.

Pigmented Leather:

This type of leather has a polymer coating with pigments, making it more resistant to wear and mold. Cleaning pigmented leather is easier, and it can withstand a bit more robust cleaning methods. However, always condition it after cleaning to prevent cracking.
