Milk of Magnesia Doubles as Deodorant

Q. I suffer from itching under my arms. I have tried many deodorants, but nothing helps.
Some time ago I read that milk of magnesia might be useful. Is that true?
A. Readers sing the praises of milk of magnesia as a gentle deodorant: “I am allergic to every kind of antiperspirant and commercial deodorant. I heard about applying milk of magnesia to my underarms and have been using it very successfully for six years. An added benefit is that there is no smell or residue on clothing. I wouldn’t go back to commercial products even if I could.”
