why does my daughters deoderant leave brown stain in armpits of her white shirts?

Answer 1

The deodorant/antiperspirant build up, which also causes yellow armpit stains, is 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 and build up of antiperspirant, try soaking the shirts in warm water with an enzyme pre-soak product. 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 then launder again. To avoid new stains from forming, always wash the shirts in the hottest water safe for the fabric. To prevent these stains, allow your antiperspirant to dry completely before dressing. Wearing a cotton undershirt under polyester shirts will help absorb perspiration.:)

Answer 2

The composition of her sweat is combining with the chemicals in the deoderant. Usually, the aluminum chlorhydrate is the culprit. Sometimes, medications can be sweat out and will do the same thing. If you want to avoid the stains in the first place, wash the armpit area with fels naptha soap worked up into a foam the first time you launder the garment. If you want to remove the stains, you can use Biz stain activated non-chlorine bleach or oxyclean undiluted directly on the stain, scrub with a brush and then launder. Some people use straight ammonia to remove these stains, but I have never had luck with that method.

Answer 3

change your deoderant! once the stains are there, they will never come out, so you have to be more careful not to let them get stained in the first place. Every time you wear the shirt, you should put a little detergent right onto the armpit area and let sit for a few mins before washing. and really, you should change your deoderant, or don't use so much!

Answer 4

Because of the chemicals. To get it out, try pouring some amonia on them and soak a few minutes before putting them in the washer. There is a deoderant called CRYSTAL which does not contain these chemicals. You can google it and buy on line. In my opinion, it works much better than the drug store stuff which also has perfumes and other junk. Good luck.

Answer 5

It probably the laundry soap your using is not strong enough to kill barters.

Try Foca and let it sit in hot water with deterrent for 1 hour. Hand scrub the area and regular wash should do it.

Also if you use 100% pure bleach that also cause yellows spots. Over longer period of time probably cause brown ones as well.

Answer 6

It happens to my white shirts too...

Normal Deodrants it WON'T happen

BUT... The heavier duty kind leaves brown-ish stains in my shirts as well

know this doesn't truly address the question BUT it's a start

Answer 7

Combination uses too much and sweats a lot. If you give it a quick scrub with an old toothbrush and some body wash, then throw into the washer with cold water, the rest should come right out.

Answer 8

Are you sure it's the deodorant?

Tar and nicotine leaves browns stains, just a thought.
