DIY Fantastic Laundry Stain Remover. I've had some tough stains that I never could get rid of. I've tried so many commercial and grocery store brands. I've found that Resolve Spray N Wash was as good as it got until I discovered this new DIY product. Mix 2 parts hydrogen peroxide to 1 part Dawn Original dish soap. Place in a spray bottle. Then spray stains 30 minutes before washing.
