How to Get Mould Off Leather

Mould on leather isn't just an eyesore—if left untreated, it can lead to lasting damage. Whether on your favourite leather laptop bag or cherished jacket, tackling mould quickly and effectively is very important. As industry experts in producing high-quality leather goods in Australia, we'll walk you through how to get mould off leather and protect your leather goods from future outbreaks.

How Mould Affects Leather

Mould is a serious issue that can compromise the integrity of your leather items, from your favourite leather jacket to your everyday accessories like leather wallets and leather belts. Leather is a natural, porous material that can absorb moisture and create a perfect environment for mould growth. This can lead to discolouration, an unpleasant odour, and structural damage.

When mould develops, it feeds on organic materials in the leather, breaking down its fibres over time. This weakens the leather and causes cracks, spots, and stains. Left untreated, mould can permanently damage your leather, making early intervention critical.

Differenttypes of leather react differently to mould, so you have to know the specific type if you want to clean it effectively. For example, aniline leather will require a gentler approach. In contrast, suede leather andPU leather (synthetic or faux leather) need special care and specific cleaning techniques to avoid harming the material.

What Causes Mould Growth on Leather?

Mould thrives in warm, humid environments, especially poorly ventilated spaces. It is particularly vulnerable if you store your leather items in damp closets, basements, or tightly sealed containers. 

How to Identify Mould on Leather

Spotting mould early can save your leather goods from irreversible damage. Recognising the signs and causes of mould helps you act quickly and effectively.

Signs of mould on leather include:

• Visual signs: Green, black, or white patches that look fuzzy or powdery.
• Odour: A musty, damp smell lingering on your item.
• Texture changes: Rough, raised spots on your leather's surface or soft, weakened areas.

How to Get Mould Off Leather

Moulding on leather can be frustrating, but you can restore your items to their former glory with the right approach. Removing mould requires careful cleaning techniques to protect the leather while eliminating the problem. Let's dive into the steps.

Note: Always check with the manufacturer first to ensure your chosen cleaning method is safe for your leather product. Not all leather products tolerate the same cleaning methods well. 

Step 1: Gather Supplies

Start with the right tools and cleaning solutions. You'll need:

• A soft-bristled brush or clean cloth
• Mild leather cleaner or diluted white vinegar (equal parts vinegar and water)
• Rubbing alcohol for stubborn mould
• Leather conditioner for post-cleaning care
• Gloves, a mask, and a well-ventilated area for safety

Step 2: Brush Off Surface Mould

Take the item outdoors or to a well-ventilated area. Use a soft-bristled brush to gently remove loose mould spores. Be careful not to press too hard, as this could push mould deeper into the leather. Dispose of the spores safely to prevent spreading.

Step 3: Clean the Leather

The cleaning techniques depend on the severity of the mould build-up on your leather items: 

For mild mould spots: 

1. Mix equal parts white vinegar and water or use a pH-balanced leather cleaner.
2. Dampen a clean cloth with the solution.
3. Gently wipe the mouldy areas using circular motions, ensuring you don't soak the leather.
4. Allow the leather to air dry thoroughly in a well-ventilated area.

For stubborn mould build-up:

1. Mix 1 part rubbing alcohol and 1 part water for persistent mould.
2. Test the solution on a hidden leather area to check for adverse effects.
3. Apply the mixture to the mouldy spots using a clean cloth.
4. Let the solution sit for a few minutes to kill the mould.
5. Wipe the area clean with a damp cloth and dry it thoroughly.

Step 4: Dry Thoroughly

Pat the leather dry with a clean cloth, then allow it to air dry naturally in a well-ventilated space. Avoid direct sunlight or heat sources, as they can cause the leather to crack.

How to Stay Safe When Removing Mould from Leather

Mould can be toxic, so removing mould from leather requires caution to protect your health and your item's integrity. Follow these safety tips to ensure a safe and effective cleaning process.

• Wear protective gear: Use a mask or respirator to avoid inhaling mould spores and gloves to protect your skin from irritants.
• Work in a ventilated area: Clean your leather outdoors or near an open window to reduce exposure to spores and help the item dry faster.
• Contain mould spread: Take your leather item to an isolated area and use disposable cleaning materials to prevent spores from spreading.
• Test cleaning solutions: Always test cleaners like diluted vinegar or pH-balanced leather cleaner on a hidden area to avoid damaging your leather.
• Dispose of materials safely: Seal used cloths, brushes, and gloves in plastic bags and wash reusable tools thoroughly to eliminate spores.

Conditioning Your Leather Post-Cleaning

Once the mould is gone, condition your leather — but only if the manufacturer recommends it. Cleaning solutions can strip the leather of its essential nutrients, leaving it dry and vulnerable to cracking.

If it's safe for the leather, apply a high-quality leather conditioner using a soft cloth, working it into the leather in small, circular motions. Focus on the areas you cleaned, as these are the most likely to be dry. Let the conditioner absorb for 15-30 minutes, then buff the surface with a clean cloth to restore its shine and suppleness. Regular conditioning restores your leather and provides a protective barrier against future damage.

When to Seek Professional Help for Mould Build-up

Sometimes, DIY methods aren't enough, especially for severe mould infestations or valuable leather items. Seek professional help in these situations:

• Extensive damage: If the mould covers a large area or deeply penetrates the leather.
• Delicate items: High-value or antique leather pieces require specialised care. Tooling leather or leather that features intricate designs also requires the help of experts,
• Persistent odour: A lingering mouldy smell may indicate that spores remain.
• Cracking or discolouration: Professionals can provide restorative treatments if the leather has already begun to crack or lose its colour.

Leather specialists can dry clean leather bags and use advanced tools and techniques to remove mould, ensuring your item retains its quality and value safely.

How to Prevent Future Mould Build-up on Your Leather Items

Preventing mould is much easier than removing it. By following these preventive measures, you can protect your leather from mould and keep it looking great for years to come:

Store Leather Properly

• Choose a cool, dry, and well-ventilated area for storage.
• Avoid basements, attics, or humid closets.
• Use breathable dust bags or garment covers instead of plastic.

Control the Humidity

• Use silica gel packets or moisture-absorbing products in storage areas.
• Invest in a dehumidifier if you live in a humid climate.
• Regularly check and address any sources of dampness near your leather items.

Regularly Clean and Condition

• Dust your leather goods weekly with a dry cloth.
• Clean them with a pH-balanced leather cleaner every few months.
• Condition leathers every 3-6 months to maintain its suppleness and protective barrier.

Use Leather Protectants

• Apply a leather protectant spray to shield against moisture and dirt.
• Reapply the protectant every few months for continued protection.
