Clean beyond the camera

It’s important to have a dust-free environment before you start cleaning your sensor. Dust is attracted to the build-up of static electricity, so opening the mirror and shutter will potentially attract particles. Avoid disturbing too much dust prior to cleaning the sensor and, of course, don’t do it outside. Once the sensor is clean, reattach the body cap or lens immediately. It’s worth remembering to put the body cap or lens on quickly when shooting on location, as leaving the sensor exposed can result in dust ending up inside the camera.
