I started doing something very simple (and maybe a little silly) to get rid of the awful sweat odor on my underarms.
When I sweat, even if I use antiperspirants or deodorants, the odor can get pretty bad… In some situations, when I am not at home, I tried doing a quick wash up (with wet pads) in the bathroom or re-applying the deodorant. Unfortunately, this never removes the odor… And of course, I cannot wash myself fully, when often I cannot even take my shirt off in those situations.
So, I started doing a simple trick that – amazingly – works perfectly. I carry around a small plastic bottle of medical alcohol disinfectant (the simplest, liquid, rubbing alcohol), and a small pack of cotton pads.
When I feel that I sweated and the odor becomes noticeable, instead of just wiping my underarms, I apply rubbing alcohol to cotton pads and clean my underarms that way. This can sting a little (but very mildly), but is amazingly efficient in removing sweat. A big advantage is that this is a dry method (alcohol neatly evaporates), and you should be careful not to apply too much alcohol on the cotton pad – you don't want it to leak around and wet/harm your shirt…
I hope this helps someone. I'm finding it to be very practical. 🙂 It is also useful when I have to completely remove odor from my underarms at home, but don't have the time to shower thoroughly. And after removing the odor, I just re-apply deodorant.
