So ive never really had an issue with cleaning up after getting messy. One thing i have had issues with is cleaning out my ears. i never seem to get it all and sometimes feel like i have water in my ears for days....
Rubbing (Isopropyl) alcohol. Pour a capful in the ear, let it sit for a few seconds, and then drain. This is a common treatment for swimmer's ear because the alcohol will dry up more easily than the water that is stuck in the ear.
Typically, I'll take a cotton ball, rip it in half, and put half in each ear, unless the mess is going to be very watery, in which case I'll wear swimmer's ear plugs.
I have had an ear infection from mud before that required a doctor's visit, so now I always at least use the cotton balls before getting messy.
