My buddy swears that Palmolive Oxy Clean dish soap is the best (and cheapest) cleaning soap to bathe in. Whether you are bow hunting or rattling bucks in close, this soap kills all human odor on your skin. He says it has no fragrance and is better than any hunters soaps. Has anyone used this?

I can't say I have used it, but this stuff? http://www.palmolive.com/products/dish-washing-liquid/oxy-plus

No.
The list of ingredients show it to contain Fragrance.
But it may just be to mask the odors of the cleaning agents.
