Dawn dish soap is a miracle! I've always have used this. My dad taught me this method. You can use Dawn alone on men's shirts for the collar. It gets out sweaty grime and stiffens the collar to new! THE best stain remover ever. Even for old stains. Every mom needs this recipe - 2 parts hydrogen peroxide, 1/2 part baking soda and 1 part dish detergent
