Ever wonder why pillows turn YELLOW?
Those yellow spots are caused by sweat. ... The face or head resting against that pillow hour after hour releases sweat, which travels through the pillowcase, into the pillow. Moisture, such as from lying down with wet hair, can also discolor the pillow, as can chemicals in some types of makeup or skin products Hydrogen peroxide, lemon juice, white vinegar, ammonia (I wouldn't mess with that), and BAKING SODA. Simply mix ONE of these products with water and soak the stain for about 30 minutes. Before the solution dries, wash the pillow in cool water with regular detergent
