Wet the concealer stain with water.
Rub bar soap directly over the concealer stain until a thick layer of soap is covering the concealer stain.
Work the soap into the fabric with your fingers. Continue until the stain is gone.
Flush the area with hot water and repeat the process with liquid dish soap if the clothes still look oily or greasy. Hand soap will remove the color of the concealer stain and liquid dish soap will remove associated oil stains.
Launder the clothes as you normally would.
