I agree with Flashy - smelly sweat is mainly due to what is eaten.

Sweating is a way of ridding the body of toxic waste. Reduce the toxic food intake and you reduce the smell.

I don't agree that using chemicals to mask a smell is a good idea.
By absorption, those chemicals end up inside you and increase your body load of toxins.

PS Natural soap and deodorants are available if you take the trouble to find out what is in the ingredients
