4. Allow the Reaction to Occur: You’ll notice the mattress stains becoming lighter as you spread the baking soda paste. This is a sign that a reaction is taking place. Open windows for ventilation and leave the baking soda to dry overnight.

5. Vacuum or Sweep: The next day, use a vacuum cleaner or a brush to sweep off the dried baking soda from the mattress surface. You’ll be left with a stain-free and refreshed mattress.
