like my hands clean.
I also not using to much water on my hikes.
There are many "dry soaps" on the market you can massage into your skin until soap and dirt falls of in flakes...
Unfortunatly also most of your upper skincells.
On our last hike on the Shetlands I got centimeter long cracks on my hands from to dry skin from the dry soap i used, the cracks caught every dirtparticle on the islands and....the salty salty air.
I found this product in a hiking shop on the islands and kicked my own product in the garbage bin.
Just use a drop of it on your hands (facial skin) rub it in until it falls of in flakes (the soap with dirt...not your skin).
The Aloe Vera moistures your skin at the same time and lays a protectice layer around them.
