The mostest bestest workingest stain removererer in the world.
Mix EQUAL parts of Ammonia, White Vinegar, and Whisk liquid detergent.
I put 1 cup of each in a spray bottle and keep it in the laundry room. Takes EVERYTHING out! Blood, permanent marker, ink, grass stains (I am a soccer mom), old grungy formula stains on baby clothes, and the list goes on and on. It is safe to use on ALL colors (from my personal experiences) and has not damanged ANYTHING.
