How to Get Rid of Sweaty Armpit Stains

I used to think that yellow stains were caused by excessive sweating or lack of deodorant. The truth is that they’re the results of chemical reactions between our sweat and anti-perspirants. It turns out that anti-perspirants contain aluminum compounds, which reduce wetness. When those compounds build-up on clothing, the end results are those unsightly yellow stains.

The easiest way to prevent yellow stains is to wear an undershirt. If that’s not possible, start reading anti-perspirant labels; they contain various amounts of aluminum compounds. Choose one that contains the lowest amount of compound while still providing moisture protection you need. It’s also helpful to let your anti-perspirant dry before getting dressed.

If you perspire while wearing a white shirt or blouse, launder it as soon as possible. If you notice the onset of yellow stains, be sure NOT to put the garment in the dryer. The heat will cause any residual stains to set, making them nearly impossible to remove. Drying the shirts in the sun will help to whiten them. By now you may be wondering how to get rid of those pesky yellow stains that are already lurking on your clothes. There are two possible solutions:

Ways to Get Rid of Armpit Stains

Option 1

Mix 1/4 cup each of baking soda, hydrogen peroxide and water. Rub the solution into a stain and allow it to sit for 30 minutes. Use a toothbrush to loosen any residue and wash it according to the directions on the garment’s tag.

Option 2

Combine two tablespoons of an oxygen-based bleach with two tablespoons of ammonia. If you’re wondering what an oxygen-based bleach is, it’s chlorine-free (think Clorox 2, OxiClean, etc). Go to a ventilated room, throw on some rubber gloves and rub the solution onto the stain for at least 30 seconds. Wash as usual, according the the article’s instructions.

Yellow stains are usually invisible on darker colors, but you’ll know they’re there if you notice a certain stiffness or reside on the underarm fabric. To freshen the clothing, fill the washing machine with cold water and add a cup of white vinegar. Allow the clothes to soak for 30 minutes before emptying the water and laundering the clothing as usual.

With the warm weather fast approaching, we’ll undoubtedly have our share of sweaty and smelly clothes landing in the hampers. Use these tips to keep yours clean and fresh or let Laundry Care do it for you.

How to Care for Clothes After Stain Treatment?

After successfully treating the stains, it’s crucial to handle clothes with care. Dry them gently and avoid using high heat, as this can set any residual stains. Store them in a clean, dry space to prevent future issues.

The Best Fabrics for Avoiding Armpit Stains

Some fabrics are more likely to stain than others. Natural fabrics like cotton, linen, and bamboo absorb sweat easily, while synthetic fabrics like polyester trap sweat, letting stains form. Wearing clothes made from moisture-wicking materials, which pull sweat away from your skin, can help reduce the chance of stains.

What to Do If the Stain Is Persistent?

Sometimes, despite your best efforts, stains might not come out. In these cases, consider professional cleaning services. Professional dry cleaners have access to stronger, industrial-strength products that can deal with tough stains without damaging delicate fabrics. If you’re dealing with a really stubborn stain, it’s better to rely on experts to avoid further damage.
