If you have body odor that won't go away even after taking a shower or bath and washing your body then you can try using some vinegar or rubbing alcohol on the areas where the body odor is lingering.
The rubbing alcohol and vinegar can kill the bacteria that could be causing the body odor which it usually does or you can bathe in some apple cider vinegar or use apple cider vinegar to wash your body with and it too will kill the bacteria that is causing the body odor.
You can also use all-natural and aluminum-free deodorant and take some supplements such as chlorophyll or wheatgrass to get rid of body odor internally.
