Few things are more disappointing than receiving a new leather item only to be greeted by a pungent, sea-like odor. If you are wondering how to remove fishy smell from leather, you are not alone. This scent is typically caused by low-quality fish oils used during the tanning process or the onset of specific types of mildew in porous hides.
Because leather is an organic material, you cannot simply wash away the scent with water. In this guide, we will explore the professional techniques for how to remove fishy smell from leather without compromising the structural integrity of your investment piece leather jacket.
I. The Science: Why Does Leather Smell Fishy?
To master how to remove fishy smell from leather, you must understand the source. According to the Leather Working Group (LWG), high-quality tanneries use stable synthetic or vegetable oils. Lower-tier factories may use cheap fish oils (cod oil) for fat-liquoring, which eventually break down.
💡 CaesarJackets：Lipid Rancidity Neutralization
Most DIY guides suggest perfume, but that only masks the problem. The fishy scent is often a result of Lipid Rancidity—the oxidation of those cheap oils inside the fibers. To truly solve how to remove fishy smell from leather, you must neutralize the oxidized fatty acids using a pH-balanced buffer. At Caesar Jackets, we only use stable, non-oxidizing lubricants, which is why our jackets arrive smelling like premium hide, never a fish market.
II. 5 Methods to Neutralize the Scent
| Method | Best For | Process |
|---|---|---|
| 1. Baking Soda Bath | General odors | Seal the item in a box with an open box of baking soda for 48 hours. |
| 2. White Vinegar Mist | pH Balancing | Wipe the surface with a 1:1 vinegar/water mix to neutralize alkaline odors. |
| 3. Activated Charcoal | Deep Saturation | Place charcoal pouches inside the lining to pull molecules out. |
| 4. Sun & Wind Airing | Mild Scent | Hang in a breezy, shaded spot. Avoid direct sun fading. |
| 5. Leather Degreaser | Oil-Based Odors | A professional degreaser pulls oxidized oils from the grain. |
III. Step-by-Step Restoration Process
If you have a cowhide jacket or a sheepskin piece that smells, follow these steps:
Identify the Source: If the smell is stronger on the inside, it’s likely the inner lining.
Dry Absorption: Use baking soda or charcoal first. This is safer than the wet methods used for removing gasoline smells.
Wipe Down: Use a damp (not soaked) cloth with vinegar to reset the surface pH.
Condition Immediately: Cleaning can dry out the hide. You must follow up with our guide on how to stop leather from cracking to replace the bad oils with good ones.
IV. Avoiding the “Fishy” Trap in the Future
The best way to handle how to remove fishy smell from leather is to buy high-quality hides from the start.
Check the Brand: Brands like AllSaints or Caesar Jackets utilize premium tanning protocols that prevent lipid rancidity.
The Smell Test: If a jacket smells like chemicals, it might just need airing. If it smells fishy, it requires chemical neutralization.
Real vs Fake: In the battle of real leather vs vegan leather durability, real leather is more porous and thus more prone to trapping odors, but it is also much easier to “restore” once the smell is gone.
V. FAQ: Smelly Leather Solutions
Can I wash my jacket to get the smell out? No. As noted in our can you wash a leather jacket guide, water can actually cause the fish oils to react further, making the smell worse.
How do I get wrinkles out after cleaning? If the odor-removal process leaves your jacket creased, see our guide on how to remove wrinkles from leather.
Will the smell go away on its own? If it’s a mild case of “new jacket smell,” airing it out works. If it is rancid oil, the smell will persist until you neutralize it with a pH-balanced treatment or soften the stiff leather with new conditioners.
VI. Conclusion: Freshness is a Sign of Quality
Mastering how to remove fishy smell from leather allows you to save a piece that others might throw away. However, your time is valuable. By investing in full grain hides from reputable sources, you ensure that your only scent is the rich, earthy aroma of quality leather.
