Yellow armpit stains on white shirts are a problem if my inbox is any indication, which I believe it is. And I’ve been avoiding the subject because honestly, it’s kinda’ gross.
I can’t begin to estimate how many email messages I’ve received asking for help with getting rid of these stains, but it’s a lot. And now it’s time. Today we’re hitting this topic head-on.
What are these stains?
Curious, isn’t it that ugly yellow stains show up only in the armpit area? Left untreated, these stains can cause the material to become stiff as if just being yellow isn’t disgusting enough. And crunchy.
Yellow pit stains happen when the protein in odorless, colorless human sweat reacts with the aluminum in antiperspirant deodorants. When an antiperspirant meets up with sweat and a cotton undershirt, it becomes a deadly combination creates those stains that appear on your white undershirts or dress shirts after only a few intense sweats.
The magic formula
Readers tell me they’ve tried everything to get rid of these stains—from vinegar to OxiClean to pouring full-strength bleach on the stains—with no success. That’s just how stubborn these stains can be. But not to worry. There is a simple process that will return your shirts to like-new appearance.
You’ll need these items:
- Blue Dawn
- Hydrogen Peroxide
- Baking Soda
- Stiff brush
Get a small bowl. Pour in 1 tablespoon Dawn and 2 tablespoons fresh Hydrogen Peroxide and stir with a spoon until well incorporated. Apply to the stain making sure the stained area is supersaturated. Caution: Hydrogen Peroxide loses its strength after 6 months, so for best results, make sure it’s fresh.
Next, sprinkle baking soda onto the area. Scrub the stain with the stiff brush and don’t be gentle. This is a stubborn stain and the longer it’s been there and built up over many trips through the laundry, the more stubborn it has become.
You want to work the magic combo of Blue Dawn, Hydrogen Peroxide and Baking Soda deep into the garment’s fibers. Make sure you are working beyond the visible margins of the stain to so that you are not missing any of the stain.
Roll that shirt up and allow it to sit for at least an hour—overnight would not be a bad idea. Launder as usual.
How to avoid yellow armpit stains
Since the aluminum in deodorants and antiperspirants is the culprit here, consider a product that is aluminum-free. These deodorants, which are aluminum-free, score well with high reviews.
If you need the extra protection of an antiperspirant, you may want to consider Klima Hyperdri Antiperspirant Serum, the world’s first aluminum-free antiperspirant/deodorant. The reviews are promising. According to the manufacturer, it takes one week of daily use to see a decrease in perspiration and four weeks of daily use to achieve full protection.
