Baking soda and cornstarch: Using baking soda as a deodorant is a simple way to combat body odor without subjecting your pits to a variety of chemicals. Mix an eighth of a teaspoon of baking soda with a little bit of water — don’t dissolve it — and rub it under your arms. You can also create a baking soda and cornstarch mix to fight odor and help prevent wetness. Simply mix one part baking soda with six parts cornstarch and dust a little on your underarms.
Lemon juice:The citric acid in lemon juice can kill odor-causing bacteria, and there are people who swear by the lemon deodorizing method.
Rubbing alcohol:Rubbing alcohol is another inexpensive and easy deodorant that kills odor-causing bacteria. Simply fill a spray bottle with alcohol and spritz your underarms with it. You can even add a few drops of your favorite essential oil to give it a scent — witch hazel absorbs oil and is mildly astringent, and tea tree oil can help relieve body odor.
You can also make some combination of the above, adding coconut oil, shea butter, cocoa butter, etc.
