You can try Zout (the squirt bottle, not the spray), Oxy-Clean, hydrogen peroxide, Nature's Miracle, white vinegar, not all at once. Follow instuctions on the commercial stuff. You can tell I've tried a lot and not all stain comes out of all fabric. Others may have better solutions. When desperate and the fabric and color will allow, I have used chlorine bleach, keeping it away from my CAG and rinsing as many as 12 or more times. I know, I'm crazy!
