Mold on a leather couch is more than just an eyesore—it can also cause unpleasant odors, damage the material, and pose health risks to you and your family. Mold grows on leather because it’s a natural material that can absorb moisture, creating an ideal environment for mold spores to thrive. Fortunately, with proper cleaning techniques and tools, you can remove mold from your leather couch and restore its beauty.

Why Mold Grows on Leather
Leather is a natural material that absorbs moisture, making it susceptible to mold in humid or poorly ventilated conditions. Mold thrives in dark, damp environments, so if your couch is in a basement, near a window, or exposed to spills, it may be at risk. Preventing and removing mold promptly is key to maintaining your couch.

What You’ll Need
Before starting the cleaning process, gather these supplies:
- A soft-bristled brush or microfiber cloth
- Mild soap (like saddle soap)
- Distilled water
- White vinegar
- Rubbing alcohol
- A leather conditioner
- A vacuum cleaner with a soft brush attachment
- Protective gloves and a mask
Step 1: Prepare the Area
Move the couch to a well-ventilated area, preferably outdoors or near an open window, to avoid spreading mold spores indoors.
Wear gloves and a mask to protect yourself from inhaling mold spores.
Step 2: Remove Surface Mold
To minimize the chances of crayon stains in the future, consider these preventive measures:
- Designate a creative area:
Encourage coloring and crafting in designated areas with easy-to-clean surfaces.
- Use washable crayons:
Opt for washable or non-toxic crayons that are easier to remove from fabrics.
- Cover your couch:
Consider using slipcovers or throws to protect your couch from spills and stains.
Step 3: Clean with a Vinegar Solution
White vinegar is a natural and effective mold-killer that’s safe for most types of leather.
- Mix equal parts white vinegar and distilled water in a bowl.
- Dampen a microfiber cloth with the solution and wring out excess liquid.
- Gently wipe the affected areas in a circular motion, focusing on moldy spots.
- Avoid soaking the leather, as excess moisture can cause more damage.

Step 4: Clean with Soap
- Mix a few drops of mild soap or saddle soap with distilled water to create a soapy solution.
- Use a clean cloth to apply the solution, wiping away any remaining mold and vinegar residue.
- Wipe the couch again with a damp cloth (using plain distilled water) to remove soap residue.
Step 5: Disinfect with Rubbing Alcohol
For persistent mold or to ensure all spores are eliminated:
- Mix one part rubbing alcohol with one part distilled water.
- Lightly dab a cloth in the solution and wipe over the moldy areas.
- Allow the couch to air dry completely.
Step 6: Condition the Leather
Cleaning can strip leather of its natural oils, leaving it dry and prone to cracking. Use a leather conditioner to restore moisture and suppleness:
- Apply a small amount of leather conditioner to a clean cloth.
- Rub it into the leather in circular motions.
- Let it sit for the recommended time, then buff the surface with a dry cloth.
Preventing Future Mold Growth
To keep your leather couch mold-free:
Control Humidity: Use a dehumidifier in rooms with high humidity levels.
Ensure Ventilation: Place your couch in a well-ventilated area, away from damp walls or windows.
Clean Spills Immediately: Wipe up any liquid spills to prevent moisture absorption.
Use Leather Protection: Apply a leather protector to create a barrier against moisture.
Regular Maintenance: Dust and clean your couch regularly to prevent dust and mold buildup.
