If necessary, gently dab the fingerprint sensor (do not wipe) with a soft cloth (not paper) dampened with a mild ammonia-based glass cleaner to remove any milky haze.
Repeat the previous steps until the fingerprint sensor completely clean (make sure there is no residual solution left over the surface of the fingerprint sensor.
NEVER DO THE FOLLOWING:
DO NOT pour glass cleaner directly on the reader.
DO NOT submerge the sensor in liquid.
DO NOT rub the scanner with any abrasive material, including paper.
