Removing sweat stains from your favorite clothes can be frustrating. Whether it is the inevitable yellow rings under the armpits or the stiff patches on your shirts after an intense day, these stains can sometimes seem almost impossible to remove. In this blog we share some proven methods to treat sweat stains effectively. We look at what causes these stains and give you tips to get rid of these dirty marks.
What causes sweat stains?
Having to remove sweat stains from your clothes is a sign that you have worked hard or had a busy day, but they also come from a mix of sweat and deodorant that reacts with the fabric of your clothes. So what is actually in sweat that creates those annoying stains? Well, sweat is a mix of water, salts, proteins, and oils that your body makes itself. This is usually not a problem for your clothes if you wash them right away. It only really becomes a problem when sweat comes into contact with deodorants.
Many deodorants contain aluminum salts that are meant to help you sweat less. These salts react with the proteins in your sweat and then make yellow or white stains on your clothes. You see this especially on white shirts or light fabrics. It is this reaction that creates those tricky sweat stains that are hard to get out. If you understand how sweat stains form, you can better choose how to tackle them or even prevent them. In a moment we will talk about good ways to get sweat stains out of your clothes.
How do you remove sweat stains?
Step 1: Make a soaking solution
Start by making a soaking solution to loosen the sweat stains. Mix 2 cups of water with 1 cup of white vinegar in a bowl or bucket. Put the stained garment in this solution and let it soak for at least 30 minutes. The vinegar helps break down the sweat residue and makes it easier to remove the stains.
Step 2: Apply the stain-removal paste
After soaking, make a paste to tackle the sweat stains directly. In a small bowl, mix half a cup of baking soda with a tablespoon of salt and a tablespoon of hydrogen peroxide. Stir it together until you get a thick paste. This mix helps dissolve stains and takes the yellow color out of the fabric.
Step 3: Scrub the sweat stain
Lay the garment on a flat surface and apply the paste generously to the stained areas. Use an old toothbrush to gently scrub the paste into the stains. Leave the paste to work for about 20 minutes, so it can do its job.
Step 4: In the washing machine
After the paste has soaked in, rinse the garment under cold water to remove the leftover paste. Then wash the garment in the washing machine on the hottest setting that is still OK for the fabric, as the care label says. Use a mild detergent to get your clothes clean and fresh.
Step 5: Drying the garment
Finally, hang the garment to air-dry instead of putting it in the dryer. Heat can set remaining stains permanently, so air-drying is the safest way to make sure your clothes are fully clean.
Treatment methods for delicate fabrics
For fabrics such as silk and wool it is important to be very careful when removing sweat stains. Use cold water and a mild detergent such as laundry sheets for wool & silk. Always test the treatment first on an inconspicuous part of the fabric to make sure there is no damage or discoloration. For silk and wool it is best to wash the fabric by hand.
Safe treatment with lemon juice and oxygen bleach
Lemon juice is natural and effective for removing sweat stains on light-colored cotton fabrics. Mix equal parts lemon juice and water and apply this to the stain. Leave the mix for an hour before you rinse it out and wash your clothes as usual. Oxygen bleach is better than chlorine bleach and you can use it on both white and colored clothes. For 3,89 euro you can order 400gr Ecover oxygen bleach. Dissolve the bleach in warm water and soak the clothes in it overnight before you wash as usual.
How should you remove sweat stains on specific fabrics?
- Cotton is durable and can usually handle water and various cleaning products well, including white vinegar and baking soda.
- For polyester or nylon, avoid using water that is too hot because this can damage the fibers. A cold-water wash with a mild detergent is usually enough.
- Linen can be washed with a mild detergent and cold to lukewarm water. Avoid wringing so you do not damage the fibers.
What should you do if you have a sweat stain?
- Tackle sweat stains as soon as possible: The sooner you get to them, the easier they are to get out. Don't let the stain dry, because then it is much harder to clean.
- Use natural products: Try natural products such as white vinegar or baking soda. These are safe for most fabrics and effective against sweat stains.
- Check the care label: Always look at the care instructions on your clothing label before you start treating stains. Some garments need special care.
What should you not do if you have a sweat stain?
- Avoid chlorine bleach: Although it can be tempting to use chlorine bleach on stubborn stains, this can actually make the stains worse and cause yellow discoloration.
- Don't use the dryer right away: Don't put clothes with sweat stains straight in the dryer after washing. The heat of the dryer can set the stains permanently. Let the garment air-dry and check that the stains are fully gone.
- Don't rub too hard: When you treat the stain, don't rub too hard. This can damage the fabric and push the stain deeper into the fibers.
Removing sweat stains is annoying, but you can often prevent them if you are smart about it. Avoid deodorants that contain aluminum. This substance can react with sweat and often causes yellow stains, especially on white clothes. There are many aluminum-free options available that are kinder to your clothes. Also wear an undershirt or invest in clothes that absorb sweat. This helps catch the sweat before it reaches your outer layer and can cause stains. Don't forget to store your clothes only when they are truly dry. Damp clothes can lead to more sweat build-up and stains when you wear them again.
