Normally, a liquid that gets its color naturally from the material it is made of (in this case Orange Juice), if it did not come out with a first response spotter like CleanMaster SpotMaster Pro XP, could be removed with a one part oxidizing stain remover like CleanMaster KnockOut 1. However, what we have found is that many foods and drinks have dyes added to them by the manufacturer to make them the color consumers want the product to be (Orange dye added to orange juice to make it "oranger"- black dye added to coffee to make it look richer - purple dye added to grape juice made from non-purple grapes). When your oxidizing stain remover is not working on stains like this, switch to your Reducing Red removing stain remover like CleanMaster RedBreak 1. The "added" color by the manufacturer will respond better to a reducing stain remover than it will an oxidizing stain remover.
