Oil-based stains should be pretreated using a solvent-based stain removal product, like Shout or Spray 'n Wash. Stain sticks are particularly convenient for collars and cuffs.If you don't have a solvent-based pretreater, apply heavy-duty liquid detergent like Wisk or Tide to the stain and work it in by gently rubbing. The pretreatment should be done as soon as possible after wearing the shirt.
After pretreatment, wash the garment as usual in the hottest water appropriate for the fabric using the recommended amount of heavy duty detergent for a regular load. Inspect the garment before drying and repeat treatment if necessary.
If the garment is dry clean only, point out and identify the stain to your professional cleaner. If you are using a home dry cleaning kit, be sure to treat the stain with the provided stain remover before putting the garment in the dryer bag.
