It’s summer. And you don’t want aluminum ruining your clean ass white shirts do you? No, you don’t. Maybe you’re a chemist and you already know this, but, deodorants that contain aluminum can inflict some serious yellow-colored blotches in the pit area when they’re mixed with only a few mLs of sweat.

I’m not trying to promote Malin+Goetz, but I’ve been using this eucalyptus odor-covering stick (also known as the poop stick, ‘round these parts) for some time. It was tested on koala bears, so you know it’s good. Just kidding, no koala bears were injured in the making of this deodorant. I tend to go undershirtless when I wear my whities and happily I’ve experienced no stains. I do have to reapply on really hot days, though.

If you’re a Complex reader (I flip through it just to see what the hipsters are wearing from time to time.), you’ll know that Jake Davis is pimpin’ another poop stick option. If Jake’s nose is anything like his aesthetic, the Dr Harris Arlington potion is probably not a bad choice for a summer scent. This stick most likely contains aluminum, the roll-on version does, so I wouldn’t suggest wearing it your whities.

Do you have any favorite aluminum-free deodorant brands?
