The most important thing to do with moldy leather is to dry it out completely so the mold stops spreading. Move the item to a dry, well-ventilated space away from your other leather goods, let it dry fully at room temperature (never with direct heat), and then research a mold-removal method suited to your item and how much growth there is. Angelus doesn't make a mold or mildew remover, so we won't pretend one of our products is the fix. Once the mold has been dealt with, we can help you clean, deodorize, and restore the leather.
Angelus has been family owned since 1907. Here's our honest take on what matters most with mold on leather, and how to bring the leather back afterward.
Quick answer: found mold on leather?
- Separate it from your other leather goods.
- Protect yourself: gloves, mask, ventilated space.
- Dry it out completely. This matters most.
- Research a removal method for your item, or see a professional for valuable pieces.
- Fix the moisture source before storing it again.
What to Do When You Find Mold on Leather
Separate the Item
Move it away from your other shoes, bags, and leather so spores don't spread. Check everything stored nearby.
Protect Yourself
Spores become airborne when disturbed. Work outdoors or in a well-ventilated space, and wear gloves and a mask.
Dry It Out Completely (Most Important)
Mold needs moisture to grow. Let the leather dry fully in a dry room with good airflow. Open bags and stuff them loosely, remove insoles from shoes, and separate couch cushions. Keep it away from direct sun, heaters, and hair dryers, which crack and warp leather.
Research a Removal Method for Your Item
The right treatment depends on the item, the leather, and how far the growth has spread. A light bloom on boots is a different job than mold through a vintage jacket's lining or deep in a couch cushion.
Test first: many common household methods can strip leather's finish or color. For valuable, antique, or heavily affected items, a professional leather cleaner is the safest choice.
Fix the Moisture Source
Mold comes back if the item returns to the same damp spot. Figure out where moisture came from, whether a damp basement, a sealed plastic bin, a humid closet, or shoes put away wet, and change it.

Clean, Deodorize, Condition
Clean the leather with Angelus Easy Cleaner and a microfiber towel to lift leftover dirt and residue, then let it dry. (On suede and nubuck, brush first with the Nubuck & Suede Kit and keep moisture minimal.) Spray Angelus Deodorizer inside shoes, bags, and seams and let it air dry 24 hours; if the smell keeps returning, moisture or growth may still be trapped in the lining. Finish smooth leather with a thin layer of Leather Balm, buffed to a mellow gloss.
Restore Faded or Stained Color
Treat a leftover mark with Spot Remover after a spot test (not on faux leather or vinyl). If the color is gone, prep with Leather Preparer & Deglazer, then recolor: Angelus Leather Dye finished with Leather Balm or Lustre Cream, or Leather Paint sealed with Acrylic Finisher. On faded suede, spray Mink Oil Aerosol over the whole item, or use Suede Renew on a single spot.
How to Keep Mold Off Leather
- Store leather dry. Never put shoes, bags, or jackets away damp.
- Let it breathe. Skip sealed plastic bags and bins; use breathable dust bags.
- Control humidity. Basements, garages, and closets on exterior walls are trouble spots.
- Keep it clean and conditioned with Easy Cleaner and Leather Balm.
- Check stored items every few weeks, especially in humid months.
Mold on Leather FAQ
Does Angelus make a mold remover?
No. We recommend researching a method suited to your item and consulting a professional for valuable pieces. Once the mold is gone, Easy Cleaner, Deodorizer, and Leather Balm help clean, deodorize, and restore the leather.
What is the most important step when leather gets moldy?
Drying it out completely in a well-ventilated space, away from your other leather goods.
Can I use vinegar or rubbing alcohol on moldy leather?
Many methods online use household acids and alcohols, which can strip leather's color and finish. Whatever you choose, test it on a hidden area first, and condition with Leather Balm afterward.
How do you get the mold smell out of leather?
Once the mold is removed and the item is dry, spray Angelus Deodorizer inside and let it air dry 24 hours. It targets odor-causing bacteria rather than masking the smell.
Can leather be saved after mold?
Often, yes, especially if caught early and dried out. Afterward, clean with Easy Cleaner, condition with Leather Balm, and recolor faded areas with Angelus Leather Dye or Paint.
Why does mold grow on leather?
Moisture plus poor airflow. Leather stored damp, in sealed containers, or in humid rooms gives mold what it needs.
