Detergent Solution

• 1). Pour 1 tbsp. of liquid dish washing detergent or laundry detergent into a mixing bowl. Add warm water, a little at a time, until you have thick sudsy solution. University of Missouri Extension, suggests this solution as one for treating mildew on a mattress.
  
  
• 2). Wipe it over the mildewed areas with a sponge or cloth, scrubbing mildew off the fabric. University of Missouri Extension advises you to avoid over-wetting the mattress with the solution, or the moisture may seep beneath the fabric, wetting the inner filling.
  
  
• 3). Allow the mattress to dry fully, outdoors and in direct sunlight.
