How to Get Grease Stains Out of Clothes
Grease stains on clothing (cooking oil, butter, salad dressing, meat fat) are oil-based and water-insoluble. Standard laundry detergent alone is often insufficient for set-in grease — you need a surfactant with stronger grease-cutting properties applied directly before washing.
Key Rule: Don't Rinse First
Water does not remove oil — it spreads it. Apply the cleaning agent to the dry stain before introducing water.
The Dish Soap Method (Works on Most Fabrics)
- Absorb excess grease: Blot with a dry cloth to remove surface oil. Sprinkle cornstarch or baking soda on the stain and allow 10 minutes — this absorbs oil from the fabric before treatment. Brush off.
- Apply dish soap: Apply a few drops of dish soap (Dawn is widely recommended for grease cutting) directly to the stain. Work into the fabric with your fingers in a gentle circular motion.
- Allow to sit: Let the dish soap work for 5–10 minutes.
- Check before washing: The stain should look lighter or translucent — the soap has broken up the oil
- Machine wash: Wash in the warmest water safe for the fabric. For cotton: warm or hot. For synthetics and blends: check the care label.
- Check before drying: If the stain is still visible after washing, do not dry — heat permanently sets grease stains. Repeat the dish soap step.
For Set-In Grease Stains (Already Washed and Dried)
- Apply dish soap to the stain and work in
- Add a small amount of WD-40 to the stain — this re-solubilizes dried grease so the dish soap can remove it. Apply dish soap over the WD-40 immediately.
- Allow 20–30 minutes, then wash in warm water
- These require patience — multiple treatments are common for stains that have been heat-set
Dry-Clean Only Fabrics
- Apply cornstarch or talcum powder to the stain immediately, allow several hours, brush off
- This absorbs much of the oil — take to a dry cleaner with the stain visible and tell them it's a grease stain before it was treated
