in regards to getting th bo out, if you use euclyptus consider that it generally comes in an oil and that will keep the odor in. so i opt for the vodka solution, believe it or not it actually is used for more then just an alcoholic drink, vodka has many uses even for making medical tinctures by steeping herbs in it for long period of time, . you can also use as a disinfectant mixed with rubbing alchol as well and keep for spraying as a cleaner. / disinfectant. contains no chemicals that way either.
if you want to work on the bo problem of someone think about cleaning the inside of the person and then they wont need to worry about bo, that can be achieved by taking herbs to kill parasites as we all have them but no one wants to talk about, bo is caused from bacteria not from sweat.
cleaning out ones system is key, lymphatic cleanse that is a hole nother chat group take care'
