that is a realtively irresponsible piece of advice. Finger prints on plastic
are very difficult to clean off without scratching the lens - even when your
use a micro fibre cloth.

The best way to check is on a day when the room is cool or cold, and the
scanner has been off for a long period, touch the surface with your
finger.  If it feels cooler than your finger, it is very probably glass;
glass is a good heat conductor, and pulls heat from your finger and
therefore feels cool.  If  it feels "neutral" or the temperature of your
finger, it could be plastic, as plastic is more thermally insulative and
therefore tends to not take warmth away from a warmer source.
