Keep the mess in the towel then throw the towel in the laundry when you get home from your trip.
DIY: Home made body wash-- Made 8/12 fairly successful...FYI using dove beauty bars turns out a very thin liquid. the best consistency was from the cheapy soaps I found at the dollar store. However, the Dove feels much nicer on the skin than the dollar store brand...what a conundrum! Will be experimenting with different brands in the future.
laundry stain cheat sheet---These are all wonderful tips, and I'd add this: while working many years as a registered nurse in surgery & critical care, I kept a bottle of peroxide handy at the desk or in my locker.....apply a little to blood stains & they lift right out. I always had the whitest lab coat & cleanest shoes! Peroxide works well for stains that are organic in nature....
