What is the difference between mildew and mold? 

We commonly hear mold and mildew, often used interchangeably when discussing leather infiltration. Is there a difference? Mold is a fungus that grows on organic matter, especially in places where moisture is high.There are different species of mold; mildew is one of them.

Mold and mildew differ in appearance and smell. Mold looks slimy or fuzzy. The color can be black, white, green, or orange. Whereas, mildew is dry, flat, and powdery. It is usually white or gray in color.

Mildew emits a mild and musty smell. Mold has a stronger and more pungent smell. Thus, cleaning mold will take more than just using household items.

Cleaning Mildew from Leather

Brush off mildew

Before cleaning leather with homemade solutions, brushing off loose particles from the leather surface should be done first. A soft-bristled brush is best used to gently remove the dry mildew. You are removing mildew spores that can grow more if left untended. 

Baking Soda

Baking soda has a pH level that is suitable for cleaning. It removes tough stains and dirt and is not harmful to leather. So it is a great alternative to removing mildew from leather. 

One way to use baking soda is to sprinkle it on the leather surface. Wait for a few hours before dusting it off. You can also use the vacuum to remove the residue; this technique is best, so it will not cause discoloration on the leather.

Once done removing loose particles with a soft bristle brush, gently rub a baking soda solution onto the leather surface.

  • Mix two tablespoons of baking soda and one cup of water to make a paste.
  • Moisten a cloth on the paste and rub the mixture gently on the area of your leather item with mildew. 

Mild Detergent Soap

Another way of removing mildew from leather is by using mild detergent soap. Mix this with warm water. Pour the solution into a spray bottle. The solution can be sprayed directly on the mildew. With a clean cloth, wipe the area where it was sprayed.

Isopropyl Alcohol and Water 

Another cleaning material available in any household is isopropyl alcohol. You need to mix an equal amount of isopropyl alcohol and water. Using a soft cloth, dampen it in the mixture and clean an area not easily visible like creases. This is to test how the leather will react to the mixture as alcohol can remove the dye.

Vinegar and Water 

Vinegar is a good cleaning agent, specifically white distilled vinegar. This can also be used to kill mildew on your leather item. Also, it has 5% acidity, and when mixed with equal parts of water it is safe to use for cleaning off mildew.

Alcohol and vinegar are good to be used as long as you don’t spray these directly on the leather surface. It is best to be mixed with water and use a cloth moistened with the mixture to wipe on the affected area. This is to prevent further damage to your leather item.

However, alcohol contains chemicals that can dry out leather easily as well as your skin if exposed when cleaning. Vinegar is natural, so it is not too harsh to be used for cleaning leather.  

Safety during cleaning 

Removing mildew should be done outside so the spores will not spread around your house. The spores can start growing on other surfaces and will be harmful to the people living in the house.

Wear a mask when cleaning so you don’t inhale the mildew particles. Mildew can also cause skin irritation. It is recommended to also wear gloves to avoid mildew getting into your skin. 

If going outdoors is not possible, vacuum the area after cleaning the leather. This will prevent the mildew particles from staying inside your house and start growing on your furniture and floor.

Mildew odor

As you clean your leather, the smell of mildew can remain in the area. Baking soda is a good odor neutralizer. Leaving a box of baking soda in the cabinet or storage area can help eliminate the mildew odor.
