This CMOS/CCD SensorVuTM cleaning kit is designed to help you remove dust and dirt from the surface of your sensor. It works when built-in sensor cleaners fail. The kit contains special cleaning wands which have soft tips made from polyurethane material. Kit includes 2 wands, one with a large tip and one with a small tip and a cleaning pad to remove the dust particle from the tip. Very easy to use. No wiping. Just dab the spot where the dust is and it will pick up the dust without harming the sensor. Wands will last many years as they can be rejuvenated by dipping the tip into cold water for a few seconds to revive the sticky surface of the tip. If oil from fingers gets on the tip, dipping the tip in warm soapy water, such as dish soap, will remove it.
