There are plants that will get you a decent lather and grease cutting effect. A friend pointed them out. Not real common in my neck of the woods.
Personally I simply use a tiny bottle of lemon Joy. No phosphates, works in hard and salt water, rinses clean and is both strong enough to clean jeans that are dirty enough to stand on their own and gentle enough to do the girlfriend's hair. trick for hair is to make a solution of a half-pint of water with just a few drops of detergent in it so it doesn't strip her hair.
In a pinch I have used clean sand and clay to wash with. Clay does a remarkably good job of removing skin oils and dirt from a body. And fun to roll in the clay with a friend. Not so good on clothes.
Cromwell & Cruthers Shave Oil. Great Googlie Mooglie. Next you will demand white Zinfidel to wash down the pan-fried rat.
You can get Shave Secret for a dollar less and without shipping for 30% more oil at just about any drugstore or Wal-Mart. Similar product concept as the C&C without the fancy name and label. Made with menthol and clove oils. A bottle lasts, at three drops per shave and shaving every day, most of a year.
Good stuff.
