Remove Crayon From Concrete

• 1). Place the ice cubes on top of the crayon for five minutes to cool the crayon to the point that it is easily chipped off.
  
  
• 2). Use a butter knife to scrap off as much of the crayon on concrete as you can. It should chip away relatively easily.
  
  
• 3). Spray on WD-40 and allow it to penetrate the stain.
  
  
• 4). Wipe the stain with a clean towel. The crayon mark will have vanished.
