My mattress had several stains, I'm sure they were a combination of drool, urine, beverages, baby spit up- you name it. Anyhow, this method really worked well. I had one pretty dark stain that I sprayed again later with a new mixture. I am amazed..
Works on every stain I've tried it on !!! The ultimate stain remover that actually works on a seriously set in stain! Never buy oxyclean again! The mixture is: 1 tsp. Dawn dishwashing detergent 3-4 tablespoons of hydrogen peroxide couple tablespoons of baking soda. Scrub on with a scrubbing brush
