Identifying and Preparing to Clean Mildew from Leather

Understanding What Mildew Is
Mildew is a type of fungus that thrives in warm, damp environments. It can grow on various surfaces, including leather.
When mildew finds its way onto your leather items, it can cause damage and create an unpleasant odor. It is essential to tackle mildew promptly to preserve the quality of your leather.
Signs of Mildew on Leather Items
Keep an eye out for spots or patches of white, gray, or black on the surface of your leather items. These could be signs of mildew growth.
You might also notice a musty smell, which is another indication that mildew may be present.
Gathering Necessary Cleaning Supplies
Before you begin cleaning, you will need to gather a few supplies. You’ll want a soft brush, a clean cloth, rubbing alcohol, water, and a leather conditioner.
Make sure you have all these items on hand to efficiently remove the mildew.
Preparing the Leather Item for Cleaning
Start by emptying the leather item if it’s a bag or removing any items it’s covering. Then, use a soft brush to dust off any loose dirt or debris.
This will prevent scratching the leather when you apply the cleaning solution.
Step-by-Step Process for Cleaning Mildew off Leather

Step 1: Gently Brush off Surface Mildew
Using a soft brush, gently sweep away the visible mildew from the leather’s surface. Be gentle to avoid damaging the leather.
Step 2: Create a Mildew-Cleaning Solution
Mix equal parts water and rubbing alcohol in a bowl to create a cleaning solution that’s tough on mildew but safe for leather.
Step 3: Apply the Solution to the Leather
Dip a soft cloth into the solution, wring it out so it’s not too wet, and gently wipe the affected areas.
Make sure the cloth is damp but not dripping to protect the leather from excess moisture.
Step 4: Wipe the Leather Clean
After applying the solution, take a fresh damp cloth to wipe the leather clean. This will remove any remaining mildew and cleaning solution.
Step 5: Dry the Leather Thoroughly
Let the leather air-dry in a well-ventilated area away from direct heat or sunlight. Avoid using any heat source, as it can damage the leather.
Step 6: Apply a Leather Conditioner
Once the leather is dry, apply a small amount of leather conditioner. This will restore moisture and protect the leather from future damage.
