This is for a new pair of unwashed raw denim jeans. I have searched and have been reading that vinegar helps seal in the color. But many say this applies only to wool and the indigo dye isn't affected by vinegar because of its alkaline? properties. Others say, vinegar only removes the stiffness in new raw jeans. And yet others say, vinegar makes a great laundry booster, as it brightens up colors (which I find a bit contradicting, when you want to keep your jeans darker). I guess, alot of people would say, just dont wash them. But I actually don't like whiskering/crease effect and I want them soft. So I want to use water. This is what I have been reading says to do: 1. washed them inside out 2. use the least amount of soap 3. wash cold and hang dry. Does anyone know or recommend anything thing else, like additive or methods that would minimize color loss.
