Before applying any solution, thoroughly vacuum the entire mattress to remove loose debris, dust, and dirt.
Use the upholstery attachment to get into crevices and along the seams.
2. Prepare the Cleaning Solution
Mix 1 cup of hydrogen peroxide with 2–3 tablespoons of baking soda in a spray bottle.
Add a few drops of dish soap.
Shake well to combine.
3. Apply the Solution
Spray the mixture directly onto the stained areas.
Be careful not to soak the mattress. Lightly misting the surface is enough.
Allow the solution to sit for 5–10 minutes to break down the stains.
4. Blot the Stains
Use a clean cloth or sponge to blot (not rub) the stains.
Start at the edges of the stain and work your way inward to avoid spreading.
Blot until the stains begin to fade.
5. Reapply and Repeat (If Needed)
