Few laundry stains are as frustrating as grease. A small splash of cooking oil, butter, or greasy food can leave a dark mark on clothing—and if the garment goes through the dryer before the stain is treated, the heat can make it much more difficult to remove.
Fortunately, a set-in grease stain doesn’t always mean the garment is ruined. With the right approach and a little patience, you may be able to loosen the grease and restore the fabric.
What You’ll Need
Liquid dishwashing detergent
Liquid laundry detergent
Baking soda, optional
An old soft toothbrush or clean cloth
Warm water, if appropriate for the fabric
A clean towel
Always check the garment’s care label before treating the stain.
Step 1: Don’t Wet the Stain Immediately
Grease and water don’t mix well. Instead of soaking the garment first, gently blot the stained area with a clean paper towel or cloth to remove any remaining surface oil.
Avoid rubbing aggressively, because this can push the grease deeper into the fibers.
Step 2: Apply Dish Soap
A small amount of liquid dishwashing detergent can help break down greasy residue.
Apply a few drops directly to the stain and gently work it into the fabric with your fingers or a soft toothbrush. Let it sit for about 10–15 minutes.
For delicate fabrics, test the detergent on an inconspicuous area first.
Step 3: Add a Little Baking Soda if Needed
For a stubborn stain, sprinkle a small amount of baking soda over the dish soap. Gently work the mixture into the stained area.
The baking soda can help absorb some of the loosened grease and residue. Don’t scrub too hard, particularly on delicate fabrics.
Step 4: Wash According to the Care Label
Rinse or wash the garment according to its care instructions. Use the warmest water that is safe for the fabric, since appropriate warmth can help remove oily residue.
Adding your usual liquid laundry detergent can provide another cleaning step after the dish soap treatment.
Step 5: Inspect Before Drying
This step is extremely important.
After washing, check the stained area before putting the garment in the dryer. If you can still see the grease mark, repeat the treatment rather than applying more heat.
Dryer heat can make some remaining grease stains even harder to remove.
What About Old, Dried-In Grease?
Older stains may require several treatments. Apply dish detergent, allow it time to work, gently brush the area, and wash again according to the care label.
Don’t expect every stain to disappear after one attempt. Repeated gentle treatment is usually better than using increasingly harsh chemicals.
Be Careful With Delicate Fabrics
Silk, wool, leather, suede, and other specialty fabrics may require professional cleaning. Avoid experimenting with household stain removers unless the garment’s care instructions specifically allow them.
For valuable or delicate clothing, taking the item to a professional cleaner can help prevent permanent damage.
A Few Mistakes to Avoid
Don’t use chlorine bleach on a grease stain unless the care label specifically permits it. Bleach isn’t designed to dissolve grease and can damage or discolor some fabrics.
Don’t put the garment in the dryer until you’re sure the stain is gone.
Don’t mix cleaning chemicals. Combining household products can create dangerous fumes or damage clothing.
The Bottom Line
A set-in grease stain can be stubborn, but it isn’t necessarily permanent. Start with a simple degreasing treatment using liquid dish soap, give it time to work, wash the garment according to its care instructions, and always inspect the stain before drying.
With patience and the right technique, many greasy laundry stains can be given a second chance.
