Really depends on the surface! If its clothing and the cloth can tolerate bleach, I recommend the Clorox Bleach Pen & Spray-N-Wash. If its colored fabric, try using liquid laundry detergent and/or Spray-N-Wash. Either way, treat the stain as soon as you're able!. . Any non-porous surface (floors, counters, etc) use Clorox Clean-Up. Carpets, I recommend Spot-Shot carpet spot care.
