I let those parts soak
my back....i clean everything else throughly too but i always feel that my back is never clean enough.
I pay special attention to what my mom called *the smelly bits*
I wash everything very thoroughly, but my face probably gets more attention because I use special soap on it in the shower, and a special moisturizer after the shower.
hair, face, privates, piercings.
Everything under water.
Armpits. I can't get the smell out.
