Moisten a clean cloth or paper towel with water an wipe it over the surface of
the handset.
If the handset needs a more rigorous cleaning, you can use:
• a mild detergent solution
• a general-purpose household glass and surface cleaner that is sprayed
onto a clean cloth or paper towel
• pre-treated cloths sold for cleaning eye glasses or camera lenses
• pre-moistened towelettes that use alcohol. Do not use any that contain
lanolin or aloe.
• Isopropyl alcohol. Do not rub isopropyl alcohol vigorously over the keypad.
The alcohol will significantly degrade the labels on the keys.
• Be sure to remove any detergent residue from the surface, using a clean
cloth or paper towel dampened with plain water.
