Most experts suggest you can use a 50/50 cleaning
solution of distilled water and isopropyl alcohol. You
should use a soft cloth such as an old cotton T-shirt
or handkerchief. Don't use tap-water, tissues, paper
towels or ordinary dish cloths.
Shut down any devices before cleaning. Dampen your
large cleaning cloth with your solution and apply very
gentle pressure, cleaning the display in a circular
motion. Let dry before turning your device back on.
Word of Caution - you should always check your owner's manual
for the recommended cleaning method for your LCD TV or Laptop
