2.Clean the glass by using a soft cloth or sponge that has been moistened with nonabrasive glass cleaner.

Do not use abrasives, acetone, benzene, ammonia, ethyl alcohol, or carbon tetrachloride on any part of the device; these can damage the device. Do not place liquids directly on the glass. They might seep under it and damage the device.

3.Clean the scanner strip by using a soft cloth or sponge that has been moistened with nonabrasive glass cleaner.
