My husband sweats excessively...which would be fine, except his sweat has a strong ammonia smell. So strong, in fact, that I have to wash the sheets every day, and when he works out he has to tie his clothes up in plastic bags, otherwise the ammonia smell permeates his gym bag, the hamper, and the closet. He has a poor diet, which I know might be the cause. However, he also has a history of kidney stones, so I'm concerned that it might actually be a kidney issue??
