Campfire Ashes

If there's one thing that camping gives you an abundance of (other than mosquito bites) it's campfire ashes.  Campfire ashes are a wonderful alternative for dish soap when camping.  (Just don't bring any non-stick cookware or the ashes will ruin it.)  The ashes are soft, yet mildly abrasive and do a great getting your pots, pans, plates and hands nice and clean.  Bonus, they're environmentally friendly and good for the soil.  Next time you forget to bring soap, just make a light paste out of clean water and campfire ashes.
