I already knew vinegar because I've always used it as an additive to washing to avoid the buildup of odors in the washing machine. My wash has finished and my bedclothes smell super fresh from pure vinegar but for dirty clothes I may need more. I'll check out borax, thanks.
I'm afraid fighting Body Odor s will be a bit more difficult for me. I've always had a bit sweaty feet and underarms, not extremely terrible but a bit worse than average. With my hormonal imbalance this has disappeared years ago along with my slightly greasy skin on my face and hands, and my dandruff also disappeared. It was so long ago I didn't even remember them.
It seems that in the last week this has been reversed. I don't know whether I should be happy or sad about it. :-) My feet are sweating, my face isn't dry and my hands are dry only if I wash them with soap. Scrubbing my hair results in a snow storm. To avoid sweating of my underarms and feet I've found only one (artificial) deo stick, fortunately that has a bearable smell but I have no clue how to substitute it. I found it about a decade ago after a lot of experimentation.
