How to Clean Armpit Stains From Leather 
Armpit stains on leather are a common problem, and it’s important to know how to clean them. Aluminum in antiperspirants, for instance, causes yellow stains. It’s also important to wear a sweat proof undershirt to avoid pit stains. You can also apply a deodorant before bed to increase the effectiveness of the product.
Avoid alkaline products
The first thing you should remember is that leather is highly sensitive to chemicals. That means that the cleaning products that you use must have the right pH value and not contain any harsh ingredients. Saddle soap, for example, is a good choice as it has a low pH level and is gentle on leather. Avoid detergents, as they will damage the leather and cause it to lose its suppleness.
The next step is to scrub away any solid material that sticks to the stain. If the stain is oily, you need to apply a cleaning agent. You can also use a wet cloth to wipe away the stain. You can also use a mild soap solution made from water, neutral soap, or saddle soap. You should also use a damp cloth to remove the soap solution. For an even more thorough cleaning, you can try using a solution of 5% white vinegar in 95% water. It will help balance the pH level and eliminate odors as well.
To avoid further damage, you should wear a sweatproof undershirt. This will prevent the armpit stains from damaging expensive clothes. Baking soda can also be used to neutralize any lingering body odor.
Avoid bleach
While bleach can be a strong chemical, it can also damage leather. You should only use it in a very weak solution, about three drops per litre. Then, use a soft, dry cloth to blot the stain. Never mix bleach with ammonium hydroxide, which is a common household cleaner.
The first step in cleaning armpit stains is to make sure that you get to the stain as soon as possible. The sooner you clean it, the less likely it is to stick. This will depend on the type of stain. If the stain is from sweat, you should pre-treat the stain with an appropriate pre-treatment. This will remove the stain as well as neutralize any lingering odor.
Bleach is not the best solution for cleaning armpit stains from leather. Bleach damages leather by breaking down the bonds that hold the dye molecules in place. If you cannot get the stain out, you should use a fabric pen or specialist leather stain to restore the color. If you are going to use bleach on leather, it is recommended that you wear disposable latex gloves. Make sure to wear clean gloves before using the bleach. Using a stiff brush will help remove dried blood stains.
Dry your clothes out in the sun
When washing your clothes, always start from the inside and apply the solution from the inside out. Doing so will avoid damaging the fabric and will help you remove the sweat stains. After applying the solution, blot the area with a paper towel and allow it to dry.
If the stain is small and does not appear on the entire garment, try using liquid laundry detergent as a spot treatment. The carbonation contained in liquid laundry detergent will help break down the stain deposits. Simply mix the detergent with water and allow the stained item to soak in the solution for 30 minutes. Once it is completely dry, set it outside to dry.
Switch to a deodorant that has no antiperspirant
If you’re tired of battling armpit stains on your leather jacket, shirt, or pants, switching to a deodorant with no antiperspirant may be the best solution. While sweat itself doesn’t stain, the aluminum salts from deodorants react with the sweat to leave ugly white marks. Luckily, most natural deodorants are aluminum-free and won’t leave behind any nasty stains.
A good deodorant dries clear. One that clumps or is pasty will cause armpit stains to appear. Using a deodorant that dries clear and dries quickly will also prevent armpit stains.
You should also switch to a deodorant that has no aluminum to prevent armpit stains on leather. While switching from a generic deodorant may cause a stinky week, it’s well worth it. It’s also better for your skin.
When you’re ready to tackle armpit stains on leather, make sure you don’t over-apply deodorant. Over-applying deodorant will only aggravate the stains and make them worse. SmartyPits is one way to apply just enough deodorant to keep yourself smelling fresh, without rubbing off too much.
