What causes Mold on Leather?
As you may already know, mold is a type of fungus and under ideal temperatures and humidity conditions, it can easily grow and feed, creating various unpleasant effects. Some of these nasty effects include:
Stains: These stains can be black, green or grey in color and may be permanent. In light color leathers, spots and marks may appear that make the leather look old and ultimately less expensive.
Mold also consumes important additives such as tannins, liquors and fat from the leather.
Ultimately, it can negatively impact the physical properties of leather.
Mold is usually invisible only when it has been growing for a prolonged period. Only when it has multiplied to the point that permanently removing it becomes extremely difficult would it be visible to the naked eye.
Wiping the surface clean will not eliminate the mold, and all that will happen is it will grow right back again. The leather product will need to be thoroughly cleaned with an anti-mold fungicide solution in order to keep it from coming back.
Another cause of mold on leather is due to the manufacturing process. In some cases, leather is manufactured in more than one tannery. It may be tanned in one place and then processed to crust in another location.
These longer storage and transporting times is what eventually leads to the growth of mold. In order to reduce this problem, leather is treated with fungicides.
The effectiveness of these fungicides are also tested in climate chambers. Leather is stored at 30 degrees Celsius and 95 to 98% humidity during the testing process.
Ultimately, during this testing process, 20 different types of mold spores will be introduced into the chamber. Leather that is not treated will deteriorate rapidly after one week, and mold tests are astringent to ensure that the leather remains without infestation for approximately four weeks.
However, despite this testing process, the leather may still become infested with mold once you have purchased items due to how you store and care for it.
