How To Safely Clean A Mirrorless Camera Sensor

How To Safely Clean A Mirrorless Camera Sensor

The sensor of a digital camera is one of the most delicate parts of the device. While lenses can be replaced, a damaged sensor poses a significantly trickier repair job. But, from time to time, you’re going to need to get in their to clean the thing and when it comes to the mirrorless variety, you don’t have to get yourself into a tight ball of anxiety in preparation.

As Photofocus’ Levi Sim shows, cleaning a mirrorless camera sensor is incredibly straightforward — when you have the right tools. As long as you’re careful, there’s nothing to get anxious about.

What you do have to figure out is just how much cleaning you need to do.

In terms of keeping dust and other lightweight particles off your sensor, a paintbrush will do the job. Understandably, you don’t want to use one that’s had paint (or even worse, some sort of solvent) on it, so make sure you have a special brush reserved explicitly for sensor cleaning.

If there’s oil or similar grime on the sensor, you’ll need swabs. Depending on the type of sensor, different sized swabs are available.

For those who aren’t a fan of video tutorials, Sim has a written version available too.

  • Is there a difference between cleaning a mirrorless vs a DSLR sensor? I’d have thought not. Other than the obvious thing of putting the camera in cleaning mode.
