How do I get the smell out of the armpits of my t-shirts?

How do I get the smell out of the armpits of my t-shirts?

I've got a few t-shirts that right out of the washer/dryer immediately smell in the armpit area. There doesn't seem to be the thick buildup from deodorant, and they don't look stained...they just smell.

How can I get that smell out? I'm just using regular laundry detergent to wash my clothes.

Try adding a scoop of baking soda to your regular laundry. That helps, as does a paste of baking soda and water applied to the pits of your shirts and left to sit overnight.

Spray some white vinegar onto them and let it soak in for a while before they go into the washing machine.

This is a known problem with "technical fabrics" -- you know, those non-cotton shirts for running etc. -- and someone invented a detergent especially for it. I haven't tried it, but it's called WIN. You could probably get it at a sporting goods or specialty running store.

You might also try cleaning the shirt with ammonia - it specifically works well for sweat. Just throw it in with the detergent at the beginning of the wash. And, of course, never mix ammonia and bleach.

For smelly stuff, I recommend a 1/4 or so of white vinegar in with the wash. Give it a try -- I know that it removes musty smell from towels that have sat too long in the washer!

That should read: "a 1/4 cup."

Try OxyClean or similar.

Seconding ammonia. Just dump some right into the machine while it's filling up. It's cheap, smells funny during the wash, but rinses away with no residual odor. Kills the pit smell entirely.

Oh, and wash them in hot water.

Vigorously rub in a good dollop of hand sanitizer, then follow everyone else's advice.

If you're lazy like me, get some Febreeze, spray it on the armpit area, toss in hamper, wash is during your next run. Ideally you want the febreeze to be on the clothes for at least a day to make sure it gets all the smell out. If your in a rush, you can just Febreeze it and be off, it'll usually get most of it.

Alternately, if you're not so lazy, you can rub some baking soda and water mixture paste on the armpit area of the shirt and let sit for a day or two.

Canesten laundry rinse - gets all of the stink out and as a bonus actually smells pretty darn good itself.

Seconding OxyClean, specifically the spray. It's amazingly effective of getting stubborn smells even out of my delicate fabric sweaters.

Try everyone's advice! BTW, there are tons of sites out there answering this question. I found some suggestions on these sites when I was dealing with a related problem: my stress sweat digs in to the fabric and is quite a bit stronger than normal, working-out, hot day sweat. The clothes are fine out of the dryer, but the smell revives in full force at the slightest hint of body heat. Some other suggestions I remember: add lysol to your laundry, add vinegar to your laundry (dab the pits on the shirts AND your actual pits too), or spray the pits on your shirts with spray used to kill pet urine odor (apparently urea is excreted through sweat as well and contributes to the staying power of the scent). The key seems to be to break down the bacteria or whatnot stubbornly clinging to the fabric. Masking this with Febreeze probably won't help. When you dab or spray, remember to do it on the inside of the clothes to attack the source and guard against any damage to the color/fabric of the shirt. Good luck.
