I use Walmart baby wipes. They have some kind of natural cleanser in them. I keep one pack plain and one pack with about a half cup of 91% isopropyl alcohol added. I use the plain ones on my face, followed up with a dampened cloth, just to wipe the cleanser out of my eyes. I use the alcohol-added ones on my pits and between my toes. Then I use the same alcohol-added one, followed up by the plain one on my crotch.
It is just enough alcohol to kill any bacteria while still having some cleanser and other things to keep the alcohol from drying my skin.
I do this baby-wipe-bath twice a day, as I am changing clothes. It only takes a couple of minutes.
I have a very, VERY oily face and very dry skin elsewhere. I was concerned that my face would get too oily, but it does not. This seems to be the best thing that ever happened to my skin. My face does not get nearly as oily as it used to, and the rest of my skin has stopped being so dry.
I have gone months with only doing this and I don't stink or feel dirty at all.
The only problem was that dead skin cells would accumulate. So, I got a "dry brush" (a stiff brush meant to be used on your skin dry) to exfoliate my skin every week or so.
Now that I have a camp host job next to a river, I wash in the river with Dr Bronner's soap once a week. I use my "scrubby-gloves" to exfoliate instead of the dry brush.
I have to say, I don't think my skin has felt any healthier my entire life.
