"Red-ex" helps to reduce and/or remove stains caused by Koolaid, fruit punch, cough syrup, some wines, chocolate, dirt, grease, soda pop stains, and other basic food-dye stains. Red-ex has been proven effective on both natural and man-made fabrics, including nylon, polyester, and wool. Unlike other similar stain removers, Red-ex does not rely on acids or common peroxides (which can distort cartpet fibers or fade colors). This product must be used with heat from a common household iron. Easy to follow instructions. 32 ounces.
