As heat waves conquer swaths of the country, your B.O. is one more thing you have to worry about.

To tackle the sour smell in your armpits, a dermatologist explained that body odor may be caused by washing your armpits the wrong way.

Experts told Well + Good the secret to smelling sweet is all in how pits are washed, revealing exactly how to clean under your arms to get rid of the odor for good this summer.

Board-certified dermatologistRanella Hirsch, MD, who is also the co-founder of skin-care brand Atolla, said the wafts of odor are born from the mixture of sweat and bacteria on the skin — and getting rid of the bacteria will fight the funky smell.

TikToker Mary Futher, known as @MadameSweat, also tackled the issue on her platform, where she educates followers about sweat and what to do if they stink.

In one clip with more than 30,000 views, Futher shows a clip of a man lathering his underarms for 30 seconds with antibacterial soap, which is touted as the key to unlocking scent-free pits.

“A good antibacterial soap has apple-cider vinegar, salt and charcoal,” Futher, the founder of Kaia Naturals, added at the end of the video.

Improper cleaning of your body — especially in the underarm area — when showering could lead to lingering bacteria, which leads to the smelly sweat even after you could’ve sworn you lathered up sufficiently. Deodorant residue and hair also contribute to the stench, which is why getting those suds going for at least 30 seconds is mandatory.

But if underarm hair is your style, Futher says cleaning the area thoroughly is vital to keep the stink at bay.

While antibacterial soaps or specially formulated underarm washes are available at the store, it’s easy to DIY a recipe that will keep your sweat from smelling. Well + Good recommends applying a diluted wash of apple-cider vinegar or tea-tree oil to the armpit area and letting it sit for 30 seconds.

Coupled with a deodorant or antiperspirant, your putrid pits will be no more.
