Canon EOS-1D X Mark III DSLR Camera (Body Only) - Manual (Page 806)

Cleaning Manually
Dust that could not be removed by automatic cleaning can be removed manually with a
commercially available blower or similar tool.
Always use a fully charged battery.
The image sensor is extremely delicate. If the sensor needs to be cleaned directly, having it
done by a Canon Service Center is recommended.
