I suddenly developed severly smelly underarm sweat. The smell would reoccur even while I was in the shower. The smell was "hormony" and could fill a room, and was not helped by deodorant, salt crystals or vinegar.
In desperation I dabbed a small amount of reconstituted lemon juice and it worked wonders. Smell gone, even from the clothes that seemed to reactivate the odour on contact.
Initially I had to put it on three times a day, but within a week once a day is enough. I cannot wait to see what real lemon will do for the problem.
I now dab and then pat a little drop in all parts of the body that develop odours.. "the crack", under breasts and groin.
I have been informed that to just be careful that a rash does not develop due to the acid mantel of the skin being disrupted. Three weeks in, I had no rashes and no odour.
