  1. Try to use an automatic cleaning setting. Some cameras offer an option to have the image sensor vibrate to dislodge dust or dirt. If this step works, you could mitigate any chance of damaging the camera. To find this setting, check your owner’s manual.
  2. Clean the exterior of the camera. Any dust or dirt that is found on the outside of the camera could slip into the chamber with the sensor once the lens is removed. You should use the brush to gently sweep dust and debris off the exterior of the camera. If you are worried about some of the more delicate parts, use a smaller brush for these places. You should use the blower to clean hard-to-reachhard to reach places.
  3. Clean the lens before removing it. To do so, remove the front lens cap and blow the dust off of the lens. Don’t use the brush on the lens, as it may cause scratches. Replace the lens cap to avoid any dust getting on the lens after cleaning.
  4. Detach the lens from the camera base. Many cameras have a button to release the lens, but the button type depends on whether you have a mirrorless or lens-style camera. However, the button is usually near where the lens and base meet.
  5. Tilt the camera slightly downward and blow dust and debris off the lens of the image sensor. Do not touch its surface or blow on it too hard as this can cause damage.
  6. Reattach the lens. After replacing the lens, repeat the photo capturing process of a white wall, white paper, white computer screen, or the sky. You will want to check for dust spots and smears in the follow- up image.
  7. If you still see spots after cleaning the camera, you may need to send it in to a shop to be cleaned by an employee.
