Oil-based stains should be pretreated using a solvent-based stain removal product, like Shout or Spray 'n Wash. If you don't have a solvent-based pretreater (Shout, Zout or Vaska Spotoff), apply heavy-duty liquid detergent to the stain and work it in by gently rubbing.
After pretreatment, wash the garment as usual in the hottest water appropriate for the fabric using the recommended amount of detergent for a regular load. Inspect the garment before drying and repeat treatment if necessary.
