Pour 1 tsp. of rubbing alcohol onto a sponge.
Place the sponge onto the surface containing the fluorescent marker stain, and rub the area gently. Continue rubbing until you have removed the marker stain.
Rinse the sponge in clean water, and wipe the surface to remove the alcohol residue.
Fabric and Clothing
Spread a layer of paper towels onto a hard, flat surface. Lay the marker-stained fabric on top of the paper towels, with the marker stain facing downward.
Pour 1 tsp. of rubbing alcohol onto a sponge, and press the sponge against the fabric so that you moisten the area around the stain, but not the stain itself.
Add another 1 tsp. of rubbing alcohol to the sponge, and apply it directly to the stained area.
Lift up the fabric, and you will see that the fluorescent marker ink has been transferred to the paper towel. Move the paper towel to a clean section, and lay the fabric back down.
Press the sponge against the stain, and continue pressing until you have removed the stain from the fabric.
Set a washing machine to the appropriate cycle, based on the fabric, and add the amount of laundry detergent specified by the bottle. Allow the machine to complete the wash cycle.
Remove the item from the washer, and check to make sure the fluorescent marker stain is gone. If it is still there, repeat stain removal process, and wash again.
Place item in the dryer, or hang it up to air dry.
