Detailed Description Tips  # Use the formula that's right for your stain. Follow the instructions.  # Because Stain Devils are individually formulated - stain removal instructions may change from formula to formula. Follow the directions printed on the label of the bottle you are using.  # Some are instant - some aren't. Be patient. While the appropriate Stain Devils formula should completely remove your stain - the time required may vary from immediately to several minutes or more.  # Combination stains. This can make stain removal a bit more complicated and may require more than one Stain Devils formula to remove it completely. But if you value your garment - it's worth the extra time.
