Remove Oil From a Camera Sensor
Removing dust and dirt from a camera sensor can be a challenge. However, getting residue, stuck-on gunk or even dust that has caked onto the sensor through moisture is an exercise in frustration. Even with the help of lens cleaning products, sensors are hard to get to and prone to scratching. In just about every instance, a tough to remove substance, such as oil or grease, will require the camera to be shipped to the manufacturer for repair or replacement.
Instructions
1. Remove the lens from your SLR by pressing the button near the base of the lens then gently turning the lens until it lifts out. This will expose the mirror. Make sure that the rear lens cap is on your lens to prevent damage to the rear element.
2. Use a lens brush to gently brush off the mirror. Hold the camera with the mirror facing down so brushed off dirt doesn't fall back into the camera. For stuck-on dust and debris, try squeezing the bulb end of the lens brush to release a puff of air.
3. Use the camera's menu to navigate to the "Clean Sensor" option. When this option is selected, the mirror will lock up, and the shutter curtains will open, exposing the sensor.
4. Inspect the sensor using a flashlight. If the problem is simply dust, clean the sensor using the same techniques as cleaning the mirror. If there is residue, oil or grease on the sensor, do not attempt to remove it with household cleaners. At best, these will leave another residue on the sensor. At worst, these can seriously damage the sensor and other components.
