There is a new thing out.... very expensive though, but I'll toss it in here.
It is mostly for severe issues. Called InterDry sheets...Haven't tried them yet though. They are over the counter.
It is available at many outlets now, and also in a new smaller less expensive price...but even then it is costly.
I find a quick wipe with alcohol under the breasts now and then (not every day) removes organisms that might take hold there.
Summer is my worst time, with it. If you have any abraded skin, avoid alcohol...it will hurt like the devil and damage the open areas worse. Hydrogen peroxide also works. We do this when bathing is inconvenient in the boonies, when we vacation.
I rarely need antifungals, but I do keep them around.
Too much moisture , bathing too often, I think makes things worse in the long run. There are benefical organisms on the skin.
Using detergent type soaps on the skin should be avoided.
We use Dove unscented only.
