My suggestion may be rather granny but after a shower, which lately I take twice a day, I dry myself thoroughly and then dust myself liberally with body powder. Having in the past had occasional issues with soreness from sweat rash, I do everything I can to avoid getting it again. My favourite is Cuticura.
It has a pleasant fresh smell and the fact that it is mildly mediated I believe helps keep away the sweat rash (a fungal infection). Obviously personal hygiene is the single most important factor. Sometimes Cuticura is difficult to get hold of, then I fall back on baby powder.
For any one concerned about talc, there are lots of talc free body powders out there, along with information on the net on how to make your own.
Hope this may help at least some.
