- Blot up any excess product with a clean dry cloth. Do not rub.
- Sprinkle baking soda over the stain to absorb the oil. Let sit 15 minutes, then brush away.
- Apply a small amount of dish soap and work in gently.
- Blot with a damp cloth from the outside inward.
- Rinse by blotting with plain cold water. Blot dry.
For set-in stains, a pre-treatment enzyme cleaner left for 30 minutes breaks down the oil effectively before washing.
