Your all-in-one, easy to use tools to clean your camera sensor. The sensor has a bad habit of collecting hard to get rid of dust and fibers. I've never messed with the sensor of my camera before. But this was as simple as can be. You spray the provided, pre-wrapped swab with a small amount of cleaner. Move the swab even across the sensor one way. Flip the swab and repeat the other direction.I cleaned my Rebel Xt sensor for the 1st time since I've owned it. And it's better than it was from the factory(as it already had a few spots of dust on it when I received it). I had to go in with some digital retouch software and remove it.Cannot recommend a product more highly than this. For is simplicity. Safe to use and affordable. Who can even find a camera center whom provides this service anymore (unless you are near a big city). For the price and about 20 minutes of your time you can do it yourself.
