What Is Sweat Made Of?

Sweat is made up of water, salt, and proteins. Sweats are mainly made up of water and salt, but it also contains other soluble minerals such as potassium.

When this mixture comes into contact with leather, it can cause the material to deteriorate.

The proteins in sweat can also create a film on the surface of the leather that will make it difficult for the material to breathe.

Why Does Sweat Affect Leather?

The main reason why sweat affects leather is due to the pH levels in the sweat.

We, humans, have an optimal pH level around 6.3 to 7.4. Generally, the pH of processed leather can range between 5 to 5.5 which is significantly more acidic than the normal range of 7.0 to 8.3 for non-leather products.

Due to the difference in pH levels when sweat comes into contact with the leather and it is not properly treated, it can cause the leather to become dry, brittle, and cracked.

In addition, the proteins in sweat can create a film on the surface of the leather that will make it difficult for the material to breathe.

This will also lead to the deterioration of the leather over time.

How Does Sweat Affect Leather Items?

Now that we have an adequate understanding of why sweat affects leather, let’s take a look at some specific ways that sweat can affect leather items.

1. Sweat Cause Stains On Leather

When sweat comes in contact with leather, it can leave stains.

The salt in the sweat will alter to form crystals on the surface of the material which can lead to discoloration over time.

These are not permanent but over time these staining may become more apparent and noticeable especially when exposed to light or heat.

This type of discoloration is usually more apparent on light-colored leather so it is important you take extra care when cleaning light-colored leather items.

2. Leather Can Absorb Odors From Sweat

Leather can also absorb the odors from sweat. This is because the proteins in sweat will interact with the tannins in the leather and cause an odor to develop over time.

The longer these smells are left untreated, the more difficult it will be to remove them.

If you have a leather item that has absorbed the smell of sweat, you can use a good leather cleaner to remove the odor.

You can also try using a baking soda and water mixture to help remove any smells that may be present on the leather item.

It is critical you get rid of sweat smells immediately as it can cause long-term damage to the leather.

3. The Salt In Sweat Damages Leather

If sweat is left on leather for a prolonged period of time, the salt in it can cause significant damage to the leather material.

The salt crystals will actually draw water and essential oils out of the pores of the leather which will lead to dehydration and stiffening over time.

This will lead to cracked leather, but it can also cause permanent damage which means that the material cannot be restored.

The salt in sweat is extremely difficult to remove so if you do see any salt residue on your leather purse or wallet, use a gentle cleanser to wipe it away immediately.

You should start this process right away before making the situation worse.

Sweat also contains other soluble minerals such as potassium.

When this mixture comes into contact with leather, it can cause the material to deteriorate.

The proteins in sweat can also create a film on the surface of the leather that will make it difficult for the material to breathe.

This will also lead to the deterioration of the leather over time.

4. Leather Can Become Discolored From Sweat

Leather can also become discolored from sweat. This is because the proteins in sweat will interact with the tannins in the leather and cause your leather to become discolored.

The longer you allow sweats to linger on the surface of your leather the more likely it will become discolored over time.

If you have a leather item that has developed stains or is discolored due to sweat, there are ways you can remove these marks at home without ruining the material.

You can use lemon juice and water mixture if your piece of leather becomes stained from sweat while vinegar mixed with dish soap can remove discolorations.

It is critical you get rid of sweat smells immediately as it can cause long-term damage to the leather.

5. Sweat Can Cause Leather To Darken Over Time

Leather can also darken from sweat. This is because sweat contains oils and proteins that can react with the tannins in the leather fibers and cause them to darken.

If your leather begins to darken due to sweat, there are a few ways to try and restore it to its original color.

You can try using a leather cleaner, but if this doesn’t work then you can try using a mixture of hydrogen peroxide and ammonia.

Make sure you test this mixture on an inconspicuous area of the leather before applying it to the entire piece.

6. Sweat Can Dry Out Or Stiffen Leather

Leather can also become dry or stiffen due to sweat. Sweat can gradually strip the natural essential oils from your leather, which will lead to it becoming dry and stiff.

If your leather begins to become dry or stiff from sweat, there are a few ways you can restore the material back into its original state.

You can use a mixture of distilled water and vinegar or even olive oil if you want to add an extra layer of moisture for better results.

It is important to do this as soon as possible as it can help prevent long-term damage to your leather.

As you can see, sweat has the ability to cause significant damage to leather items over time which is why it’s so important that you get rid of them as soon as possible.

How To Prevent Sweat From Leather

At this point, you might be wondering how to prevent sweat from leather in the first place.

Here are a few tips to help you out:

  • Make sure to give your leather items time to dry after sweating. Do not put them back into storage when they are still wet as this will only cause more damage over time.
  • If you have a leather item that is starting to smell from sweat, use a gentle leather cleaner to wipe away the residue. Do not scrub or rub the area as this can cause further damage.
  • If your leather item is starting to discolor from sweat, try using a mixture of lemon juice and water or vinegar and dish soap mix to remove the marks.
