1. Mix water and hydrogen peroxide in equal parts. Apply sparingly to stain, let sit for five to ten minutes minutes, then scrub with a soft scrub pad or a soft-bristled brush.
2. For deeper stains, mix hydrogen peroxide and baking soda into a bubbly paste. Apply the paste to the stain and let sit for five minutes. Wipe clean with a damp, warm towel.
