Good Thread!
My friend uses apple cider vinegar (brown vinegar not white) between his toes to prevent athlete's foot/toes (he says it works).

He says it's also good as a window cleaner.

He uses olive oil on his dry skin. I told him because he used vinegar between his toes and olive oil on his skin, he should stick a cucumber and tomato in his mouth and I would call him a "walking salad". I'm laughing as I'm typing this.
