YellowGo recovers dye-stained fabrics by removing unwanted dye. Results on whites are excellent. On colors, you have nothing more to lose and everything to gain by trying YellowGo. YellowGo may take out the color you want to keep. But if it removes the unwanted dye without damaging the underlying color. YellowGo can also be used to remove the last traces of ink and many other residual stains. YellowGo is a Titanium Sulfate based reducing bleach, and is packaged in Gallons and Quarts. Note: YellowGo often throws a sediment that can be found in the bottom of the bottle. This material is responsible for stabilizing YellowGo while it is still in its bottle. These stabilizers work equally well while in solution or as a sediment. Having this sediment fall out of solution does not damage the YellowGo in any way.
