how to clean underarms yellow stains on white t-shirts?

Answer 1

Deodorant and Perspiration Stain Removal
Yellow underarm shirt stains are likely caused by a combination of deodorant and perspiration. Many deodorants and antiperspirants contain aluminum salts. When these salts are combined with laundry detergent, especially in cooler water settings, they are not easily dissolved, and they remain on the fabric.

To remove the stains, try soaking the shirts in warm water with an enzyme pre-soak product or rubbing the soiled area with white vinegar. Wash in the hottest water safe for the fabric. If the stain remains, dampen and sprinkle stain with meat tenderizer. Let stand for about an hour, and launder again.

To avoid new stains from forming, always wash the shirts in the hottest water safe for the fabric. Also, allow antiperspirant to dry completely before dressing....:)

Answer 2

On white T-shirts you can use hydrogen peroxide, it will react with the proteins in the stain to help break it apart. Start with half strength (1/2 water and 1/2 hydrogen peroxide), pour over the stain and let it sit for 30 minutes, then launder and air dry. If the stain is still there, soak with full strength hydrogen peroxide let sit for 30 minutes wash and air dry again.

This should do the trick.

Next time try ironing baby powder under the arms of your new T-shirts. It creates a barrier and naturally whitens the shirt.

Answer 3

Since you did not say whether or not the t-shirts have designs or graphics, I'll assume they do to be safe.
My FAVORITE is always OXYCLEAN...the powder. You can soak the shirts in a pot with a mix of OXYCLEAN and water, and it should do the trick. IF NOT... buy a spray bottle of TILEX mold and mildew remover. Spray it directly onto the stains, and let it sit a few hours. Launder as usual, but don't mix it in with colors that might be affected by bleach.
If they are plain white shirts, you can soak them in bleach and water for a couple hours and then wash.
GOOD LUCK!

The yellow marks are caused by ingredients in your antiperspirant. Specifically, the aluminum salts used in antiperspirants to stop you from sweating can form an acidic complex that stains shirts yellow. (Cotton shirts are particularly susceptible to this reaction.) You can switch from using antiperspirants (which cause staining) to deodorants (which don't). Of course, then you'll sweat more. Finally, if you rinse your shirts in cold water before you wash them, you'll greatly reduce the amount of staining. Washing, especially in hot water, can make the stains worse.

My husband tried just going with deoderant, but found that he couldn't deal with the sweaty armpits. I now soak his white undershirts and socks in a bleach/water mixture for 30 minutes before washing.

Answer 5

Use a good detergent. I never had this problem until the local stores stopped selling Oxydol. Now I've tried tide & cheer, and they suck. I'm currently trying different detergents and oxidizers. Bleach doesn't really seem to help, is hard to rinse the smell out, and wears your clothes out prematurely. I'd love to see Jeff keep up with laundry for a family with 2 teenagers who generate 10~15 loads a week.
