How do I clean the scanner glass on the HP Laserjet Pro 400 MFP M425?

Turn off the product using the power switch and unplug it, then open the scanner lid and clean the glass, document feeder strips, and white plastic backing with a soft cloth or sponge moistened with nonabrasive glass cleaner. Dry all surfaces with a chamois or cellulose sponge to prevent spotting, then plug in and turn the product back on. Do not use abrasives, acetone, benzene, ammonia, ethyl alcohol, or carbon tetrachloride, as these can damage the product. (Page 6)
