Mix ½ teaspoon (2.5 mL) of dish soap with 1 cup (0.24 L) of warm water. Pour the mixture directly onto the stain. Blot the stained area dry with a paper towel. Repeat the dish soap and blotting steps until the stain is gone.
Stir the mixture thoroughly until the water becomes sudsy. Make sure the entire stain is covered with the mixture. You want the affected area to be soaked with the mixture. Try to soak up as much of the liquid from the soap mixture as you can with the paper towel. Vacuum over the area if you’re having a hard time removing the excess liquid from the mixture. Make sure you rinse the stained area with warm water after you finish so there's no leftover soap. Dry the affected area with paper towel when you're all finished.
