Never touch the mirror with your hands or a brush, and do not scrub the surface of the mirror
with a cleaning cloth. Instead, use a cleaning cloth to clean the mirror with a light touch, and do
not put any cleaning solvents on the cloth or the mirror. Do not apply pressure to the projector
lens or mirror.
