Things You'll Need
Expo is a brand of dry erase markers that write on special boards. These boards are used frequently by teachers. Though Expo markers may be wonderful tools, when the ink ends up on your couch, you must act quickly to remove the stain left by the marker.
Fill a bowl with hot water, and squirt a bit of liquid soap into the bowl.
Dip a soft sponge into the solution, and use it to gently scrub the Expo marker stain on your couch.
Scrub the stain with the soap and water until the stain is gone, or reduced as much as possible. Allow the area to air-dry.
