How to Remove Cooking Oil Stains From Upholstery

Sprinkle a thick coating of baking powder onto the stain and let it sit for 20 minutes. It will pull most of the oil out of the upholstery without any damage to the upholstery. Then use a vacuum cleaner to remove it.
Pour a few drops of liquid dish soap onto a small brush (you may use a tooth brush or any other soft brush) and scrub the dish soap into the stain. The soap will naturally break up and remove the grease or oil. Repeat until the entire stain has been removed, re-applying fresh dish soap and scrubbing more as needed.
Moisten a clean white cloth with water and blot the stained area to remove any remaining dish soap or oil, and allow the area to air dry.
If the stain is too big and doesn't go after the process described above, we recommend a professional carpet cleaning service to prevent ruining your furniture.
