spot remover for clothes -- gets out wine, armpit stains, etc. I used 1/2 cup Dawn, 1 cup Hydrogen Peroxide and 2 T Baking Soda, mixed it in a bowl, dipped my scrub brush in it and scrubbed the collars and underarms of my husbands white t-shirts. I let it sit for an hour and washed it in hot water with a little of my laundry detergent and BAM!!! Amazing!
