## Key points

- Don’t blow on a camera sensor with your mouth.
- Saliva can leave marks visible in photos.
- Try the built-in cleaner or a rocket blower first.

## Summary

Photographers should avoid blowing on an exposed camera sensor with their mouths when trying to remove dust. Saliva can leave stubborn stains that appear in photos, making a minor speck of debris a more serious and potentially costly problem.

The article recommends first using a camera’s built-in sensor-cleaning function, which vibrates to shake off dust and can often be set to run automatically. If specks remain, a rocket blower can direct air at the sensor; pointing the camera down helps gravity carry loosened particles away. For persistent dirt, professional cleaning is safer than experimenting and risking a scratch.
