How to clean mirror inside dslr camera

Learn the step-by-step process to effectively clean the mirror inside your DSLR camera for optimal performance and image quality.

Keeping your DSLR camera clean is essential for maintaining the quality of your photos. One important part of the camera that often gets overlooked is the mirror inside the camera body. A dirty mirror can lead to dust and smudges appearing in your photos, so it’s important to clean it regularly.

Before you start cleaning the mirror, make sure to turn off your camera and remove the lens to prevent any damage. You’ll need a few tools for this task, including a blower, a soft brush, and a microfiber cloth. Avoid using harsh chemicals or abrasive materials that could scratch the mirror.

To clean the mirror, start by using the blower to gently remove any loose dust particles. Next, use the soft brush to sweep away any remaining debris. Finally, use the microfiber cloth to gently wipe the mirror in a circular motion, being careful not to apply too much pressure.

    When using the blower, is it okay to point it directly at the mirror, or should I keep it at an angle? I’m a bit worried about blowing dust further inside the camera.

      It's best to hold the blower at an angle rather than pointing it directly at the mirror. This helps prevent dust from being pushed further inside the camera.

  2. How often should I really be cleaning my DSLR mirror? I use my camera quite frequently, especially for outdoor shoots, and I want to maintain its quality without overdoing it.

      It's generally recommended to clean your DSLR mirror whenever you notice dust or dirt affecting your image quality. For regular users, checking after significant shoots can help maintain optimal performance.

  3. Don’t forget to clean your workspace too! I once cleaned my camera in a dusty area and ended up with more dust on the mirror afterward.

  4. I disagree that you should clean your mirror too often. I've found that cleaning it every few months works for me, and I don’t have issues with image quality. Over-cleaning might just risk damaging it.

    • Logan Carpenter July 26, 2026 at 6:15 pm

      That’s a fair point. I guess it really depends on how much you use your camera. I’d be cautious but also want to avoid unnecessary wear.

  5. I recently followed these steps to clean my DSLR mirror, and it worked wonders! I was worried about damaging my camera, but using the blower and microfiber cloth made it easy. Just remember to be gentle! It’s also a good idea to clean the sensor while you’re at it, just be extra careful with that part.
