What's the best stain remover for antiperspirant residue?

Try spraying them with a topical stain remover such as Shout or Spray n’ Wash. Spray and then let them soak for an hour or two before running the machine. Don’t dry them in the dryer until you see the stains are gone.

Soilove Laundry Soil-stain Remover works well, makes a shirt look new again. You can find it on Amazon.com (Shout, Spray n Wash didn’t work on underarm stains in my shirts.)

What ever happened to dress shields? I never used them but they were pads you put on the under arms to protect your garments. You would think they would have relay thin easy ones now.

Try using lemon juice, vinegar or baking soda. You can also make a solution of sodium percarbonate (2 ounces per gallon)- have those stained clothes soaked for about an hour or overnight, then rinse. Should there be unused solutions, you can use those to clean your toilet.

My son inherited heavy perspiration from his father. None of the antiperspirants do much for him, either. I always thought the yellow-brown stains are from the sweat itself. My son wears cotton undershirts to absorb the sweat. Those can be washed in hot and bleach and replaced more cheaply than the shirts. He’s in his early 20s and has a blue-collar job, so he’s not often in dress clothes, though.

There is a lady on the radio here who has all sorts of natural solutions for stains. I just heard something about this problem but I forget, I will check on it for you.

A friend turned me on to Oxy-Clean and I’m addicted to it. If you make it into a paste, and put it on the stain, let dry and soak it, it might work for your stains.
