Q. Thank you so much for writing about using vinegar and water on underarms. I have had a problem with smelly underarms most of my life and have tried almost every product on the market.

I tried plain white vinegar, and it worked so well I’ve kept it up ever since.” Diluted vinegar should be applied only to unbroken skin (not after shaving), or it will sting. If it causes any rash or other reaction, it should be discontinued immediately.
