If there is dirt or tape residue on your SuperDeker, it is recommended to use a Mr. Clean Magic Eraser to clean the surface of the game.  Get the eraser damp and clean the whole surface of the game, then dry off with a soft cloth.  DO NOT use Windex, or any alcohol or ammonia based cleaner.  Reapply three squirts of the Zero Friction Ice Spray to both halves of the ice surface and wipe around with a soft cloth just like waxing a car.  Keep in mind that using too much spray can cause the game to slow down.   TIP:  If the puck slides off the game, please clean it before putting it back on the game, so it does not track dirt on to the playing surface. A dry  dusting/Swifffer cloth and applying the spray once a month should be all needed.
