Wipe all stains with a whiteboard cleaner according to the directions on the container.  If any stain remains, apply all purpose cleaner according to the directions on the container.  If the stain persists, saturate a cotton ball with rubbing alcohol; blot the remaining stain and rinse.  Or, you may use Clorox Clean-Up Cleaner (spray bottle) according to the directions on the container.  You may also try the following: Use another color dry-erase marker over the stain and wipe off while ink is still wet.  Sometimes, using another color marker over the color, lifts the under color when erase. 

ADDITIONAL NOTES: If whiteboard surface is porcelain, the dry-erase marker should erase easily.  If the whiteboard surface is laminate, use the suggestion provided.  NOT RECOMMENDED: Soft Scrub or any abrasive cleaner.

To make the paint easier to remove, wet the paint and wait five (5) minutes.  Spray area with the highest setting on a garden hose nozzle, as close to the paint as possible and at a slight angle.  If any stain remains, wet the area and brush with a stiff bristle nylon brush or broom.  Rinse away completely to prevent paint from redepositing on the surface.
