Pillows commonly turn yellow for many reasons. Sweat, makeup, saliva, oil from your hair and skin, and regularly lying down with wet hair are frequent culprits.
Washing pillows twice a year can help prevent stains, but if yellow has already set in, you can get rid of the unsightly discoloration in several ways.
We recommend using just enough baking soda to cover the stain so you don't create a mess, and be sure to wipe away the excess before putting it in the washer.
Add some vinegar to your baking soda pre-treatment for an added effect. Once the baking soda has sat for 30 minutes, use a vinegar-dampened cloth to blot the stained area.
Dissolve four tablespoons of salt in one liter of water, stirring thoroughly until it is all dissolved. Gently dab the stains with the salt water with a cloth or sponge.
Cover the stain with shaving cream and let it sit for about two minutes. Work the cream into the stain with your fingers or brush and repeat until the stain is gone.
