Details On Why Leather Smells Like Fish

I took some time off to research on why leather smells like fish. I found some interesting reasons why this happens and I’m ready to share with you everything I have found. Enjoy!

1. Oil In The Leather Tanning Process

One of the basic causes of leather smelling like fish is the oils used during the tanning process.

Tanning is an important process in leather making. Tanning is what basically turns the raw animal skins into leather.

But during this leather tanning process, some leather tanners or retailers will use cheap fish oils that have not been filtered to treat or soften the leather.

Filtrated fish oils will usually be rid of that distinctive fish odor and will not result in a fishy stench on leather once tanning is complete.

These cheap oils result in unsaturated bonds that react with the air which then causes it to go rancid and results in the fishy smell we all hate to have on our leather.

When leather becomes smelly this way, it’s usually a lot harder to deal with.

This is because these unfiltered oils used to treat leather during the tanning process seep deep into the fibers of the leather.

So simply washing or airing out the smell will usually not cut the smell from the leather.

What eventually happens is, the smell gradually gets worsened by the day – depending on how much heat, moisture, and sun the leather is exposed to.

With all these said, it begs the question, why then is it that the fish smell is usually not noticed when the leather item is first purchased at the shop?

Of course, you might not notice the smelly fishy odor in the shop when you’re picking out the leather item because the fish oil treatment will mostly in the initial stages have a fairly good smell.

After a while these oils begin to breakdown chemically, then the fish smell is released.

Fish oil is a very common oil used in the leather industry during the leather tanning process.

But it’s essential only high-quality fish oils are used because it’s more stable and does not deteriorate or go rancid.

2. When The Leather Becomes Wet

Another very come phenomenon that causes leather to smell like fish is the leather getting wet or damp without properly drying it.

This will particularly happen if you clean your leather items and do not allow them to properly dry.

Leather goods have to be maintained from time to time to keep it in good condition.

A typical maintenance routine for a leather article will usually involve cleaning and conditioning the leather item.

There are also some restores and leather protectors you can also use to ensure your leather goods are in top-notch condition.

A common rule of thumb is usually to allow the leather to air-dry after cleaning or conditioning is complete.

The best way to dry off the leather is leaving it in a cool dry place.

But depending on which part of the world you are in, the leather may not dry properly and can eventually cause the leather to have a smell similar to that of a fish.

3. Sweats

During the hot seasons, our leather apparels and accessories absorb a lot of sweat.

Over a period of time, the sweat gets absorbed deep into the leather and the salts from the sweat will begin to deteriorate.

So if the leather item is not cleaned properly and timely, it begins to build-up.

The stench that can come as a result of sweat build-up can be all sorts of smells.

From a smelly fishy odor to a funky meat smell to a dead rat smell and everything in between.

I apologize if I have gross you out in any way but the good news is this type of smell is a lot easier to deal with.

4. Not Properly Storing The Leather Item

Leather is a very porous material and so it tends to easily assimilate smells and scents around it both good and bad.

Meaning if the leather is not properly stored or placed, it will take up whatever smell or scent that is around it.

For the leather to smell like fish, it will not necessarily have to be put around fish.

Of course except for rare instances where your leather somehow literarily came into contact with fish, hence the fishy smell.

What I find happening most of the time is that the leather if not properly stored will assimilate a combination of bad smells over a time period and the combination of smells will sometimes reek of something similar to that of fish.

So properly storing your leather items is definitely one way you will be able to ensure your items do not reek of fish-smell or something similar to that.

5. Aging

In instances where the leather has lived its lifespan and has aged, leather goods, especially the ones without proper care and maintenance, can possibly develop such foul smell.

Leather was once the skin of an animal so without proper care and as it ages, it will begin to deteriorate resulting in all kinds of defects like stinky smells, mold, mildew, discoloration, etc.

6. The Glue Used

Another possible cause for the fish smell on your leather items is the type of glue that was used to make the item.

So whether it’s a wallet, a purse, a jacket, a pair of shoes, or boots, I’m basically referring to the glue that was used to assemble the item before the leather item was stitched together.

Usually, there are two ways the glue used can cause the leather item to smell like fish.

The first is the type of glue used. There are some glues that some leather goods manufacturers or leather crafters use that will have a stinking fish smell.

Although the smell from these types of glues is often said not to linger on the leather for a long time, some would anyway.

The fishy smell will be more apparent especially when the leather item is new.

One particular type of glue I have found that causes a fish smell on leather goods is the Copydex glue.

Another way glue can cause the leather to have a fish smell is when the glue used to assemble the leather item ages and begins to breakdown.

For leather jackets, shoes, etc, you can set the cup in a drawer or a wardrobe and leave the leather item in there with it.

Be careful the cup filled with the white vinegar does not tip over.

Step 4: Allow the cup to sit with or inside the leather item overnight. You would want to check to see if the odor remains the next day.

Leave it for an additional couple of days if you find the fish smell still persists.

Step 5: If you find there is still a bit of fish smell lingering on the leather item, replace the cup of white vinegar with a cup of baking soda or some pieces of charcoal if you have some leftover lying in your barbeque grill.

You would want to repeat the entire process a couple of times to ensure the fish smell is completely removed.

2. Newspaper And Baking Soda Method

This method is also an awesome way to remove the fish smell from your leather without getting your leather item wet.

Step 4: Unwrap the leather item and use a vacuum cleaner or soft brush to remove the baking soda residue.

3. White Vinegar Method 2

Still, on the application of white vinegar, it can also be applied in another way to remove the fish smell from leather.

This is a great method for removing smells stuck on the outside parts of leather goods like couches, jackets, bags, etc.

Step 5: Leave the leather item to air dry.

Lemon is great when it comes to removing fish smells and general smells from leather.

So you will be able to use lemon to also remove fish smells from your leather goods by following this simple application procedure.

Things Needed:

  • Lemon
  • Microfiber Cloth
  • Warm water

You can sift the lemon juice so that the lemon fibers are removed.

You would want to ensure the warm water is enough to dampen the microfiber cloth about 2 to 3 times.

Also, make sure the warm water is well saturated with the lemon juice.

Step 2: Dampen the microfiber cloth with the lemon solution.

You can also wipe the inner parts of the leather item if the smell has permeated the interior or linings.

Once dry, check if the fish smell still lingers. If it still does, you can try the process again one more time.
