Sodium percarbonate is washing soda and hydrogen peroxide (32.5% peroxide) in powdered form. When activated by water, it can be used to gently lift stains from a wide variety of items or to deodorize. It is a popular ingredient in many products that are meant for whitening and brightening. To use, sprinkle a little of the boost on a stain and spritz with water, or you can make a paste and scrub it into the item. Allow it to sit for 20 minutes or up to 12 hours before washing as normal. I recommend doing a spot test first when using on colored clothes to be sure it does not fade the fabric. As a laundry boost, you can add 1 to 2 tablespoons to your load of laundry. You can use this on: - pots - pans - clothes - countertop stains - grimy stovetops - bathtubs - showers - toilets - upholstery - carpet cleaners and more!
