and dirt particles. 
R

R
  Use a dry, soft MicroFiber cloth, such as a lint free polishing cloth, to gently wipe the 
glass to remove any dust or dirt particles. 
R
  If the glass needs additional cleaning, slightly moisten the cloth with a diluted mild 
soap or mild detergent solution, or use a compressed air duster (spray can type).
