Procedure

• 1). Blow off whatever dirt or dust off the exterior of the Plexiglas that you can.
  
  
• 2). Wet the surface. Form a coating of running water that allows the dirt to roll off.
  
  
• 3). Use a cleaner made with water and a tiny amount of dishwashing detergent. Place the solution on a sponge or soft cloth and wipe the Plexiglas lightly. If your cloth becomes dirty in one area, use a cleaner portion of the cloth to avoid scratching the surface with dirt.
  
  
• 4). Wipe the Plexiglas with clean water and dry using a lint-free cloth.
