How to Clean a DSLR Mirror?

Whether you invest in an expensive digital camera, it’s vital to understand how to maintain it. If your photographs have stains, smudges, or other flaws, it’s time for your DSLR to get cleaned.

DSLR cameras are amazing pieces of technology, but they can be a bit tricky to clean. If you don’t clean your camera properly, you could end up with a lot of dust and dirt on the sensor, which will affect your pictures. In this blog post, we will teach you how to clean your DSLR mirror safely and effectively.

Why Do You Need to Clean Your DSLR Mirror Camera?

In the same way that any other piece of equipment benefits from cleaning, your camera reaps the same benefits. To begin with, by cleaning your camera, you ensure that the mirror and sensor are free of dust, dirt, and other debris that lowers the quality of your photographs.

The last thing you want is to capture a beautiful photograph of a loved one or an amazing landscape, only to discover that the picture quality is terrible due to the dirty camera.

Second, regular maintenance will ensure that your camera keeps operating at its best.

When it comes to maintaining your vehicle, you probably don’t think about how often it requires an oil change. Your camera, like your automobile, also needs routine maintenance in order to keep the mirror and sensor clean, particularly given the number of hazardous dangers it faces [1].

Frequency of Cleaning

How often you need to clean your DSLR mirror camera depends on how often you use it. If you’re shooting a photo every day, then you’ll want to clean the camera once a week. If you only take pictures occasionally, then cleaning it once a month should suffice.

Frequency of Cleaning

No matter how often you shoot pictures, always be sure to check for any dirt or debris on the lens and mirrors before taking each picture. By doing so, you can avoid ruining photos with spots and streaks.

For most of us, a few dust specks here and there aren’t going to ruin our day, and even if there are visible dust specs, they may be removed in Photoshop. However, if your camera is really dirty and you don’t clean it, the spots will only get worse over time.

Second, if you frequently exchange your lenses, your cleaning routine will need to be more frequent. The front element of your lens is constantly exposed to the environment and can easily attract dirt, dust, and other particles.

When the lens is removed from the camera body, dust will enter regardless of whether or not you change lenses. That big opening is a tremendous invitation for the dust to enter via the mirror and sensor because it provides so much breathing room.

This is especially true if you have a lot of outdoor shooting in dusty or windy places.

Finally, the frequency with which you clean your sensor is determined by how pleasant it is for you to perform it.

Preventative Measures

It’s important to emphasize that there are a few things you can do to extend the time between DSLR camera cleanings:

  • Minimize lens changes. If you can help it, don’t change lenses as often. This will minimize the amount of dust that gets into the camera body and onto the sensor;
  • Be aware of your surroundings. When shooting outdoors, be conscious of your surroundings and try to avoid areas with excessive dust or sand. If possible, shoot in sheltered areas where there’s less chance for windblown particles to enter your camera;
  • At all times, avoid changing lenses in a dirty or windy situation. If you’re changing lenses and there’s a lot of dust in the air, try to find a clean, sheltered area to do it in;
  • Keep your camera stored in a dry place. If possible, keep your camera stored in a dry place when not in use. Humidity and moisture can cause corrosion on the mirror and other internal parts of your camera.

Preventative Measures

  • When replacing lenses, hold the camera body perpendicular to the ground. This will keep the dust out of the camera and make it easier to clean when you get home.
  • Wipe down the lens caps and body caps on a regular basis. The less dust there is on your camera’s lens, the less dust it picks up;
  • Clean your camera bag on a regular basis. There’s no sense in cleaning your DSLR camera if you put it into a bag that already contains dirt and other contaminants;

These are just a few tips to help prevent dirt, dust, and other particles from getting into your camera and onto the sensor. By following these simple guidelines, you can minimize the amount of cleaning that’s necessary and extend the time between cleanings.

Cleaning Tools

  • Blower. A blower is probably the most essential tool for cleaning your DSLR camera. It’s used to remove any loose particles from the lens and mirror;
  • Lens brush. A lens brush can be used to clean dirt, dust, and other debris from around the edges of the lens barrel;
  • Cotton swabs. Cotton swabs are great for removing fingerprints and other smudges from the front element of your lens;
  • Isopropyl alcohol. Isopropyl alcohol can be used to clean the sensor if it becomes dirty. Be sure to use a cotton swab or microfiber cloth when doing so, as you don’t want to scratch the surface of the sensor.
  • Sensor gel stick. A sensor gel stick is used to remove dried-on contaminants from the surface of the sensor. If your camera has a lot of built-up dirt and grime, this may be the best way to clean it;
  • LensPen [2]. A LensPen can be used to clean fingerprints and other smudges from the lens barrel. It also comes with a brush on one end and a cleaning cloth on the other end for more thorough cleaning;

Cleaning a DSLR Mirror Camera

1) Cleaning the viewfinder

If dust appears in your viewfinder but the pictures are clean, it’s simply because your viewfinder needs to be cleaned. To reach into the corners as needed, use a soft, lint-free cloth or a cotton swab. If there is a lot of dust, you can use compressed air to dislodge it [3].

2) Cleaning the lens

Before cleaning the lens, make sure it’s free of dirt and dust by blowing on it or using a blower. If there is still dust or other particles on the lens, you can use a cotton swab dipped in isopropyl alcohol. Be very careful not to scratch the surface of the lens.

As you work, keep the camera open and your tools handy so that you can check your lens as well. Examine the outside lens for dust or smudges after removing the lens cap. Simply breathing on it may often clear away any condensation and then wipe it off with lens tissue or a clean microfiber cloth. If this doesn’t do the trick, add a drop of lens cleaner and then wipe it down with the lens tissue.

Wipe in a circular motion, starting in the middle and working your way out. Allow for drying after cleaning the lens before inspecting it to see whether it needs another round or not.

Remove the lens from the camera and repeat the procedure for the rear lens.

Tips for users: do not use any type of household cleaner (Windex, 409, etc.) or glass cleaner on your camera lenses as they may contain ammonia which will damage them!

3) Cleaning the mirror

To clean the mirror itself, hold the camera so that the front is facing down and gently blow on the mirror with your blower. This will remove any loose particles. If there is still dirt or grime on the mirror, you can use a lens brush or cotton swab dipped in isopropyl alcohol to clean it off. Just be sure not to touch the mirror surface with anything but the brush/cotton swab as this could damage it.

If your DSLR mirror becomes dirty, you’ll need to clean it using a special tool designed for that purpose. One such tool is called a sensor gel stick. This is a long, narrow rod with a sticky substance on one end that is used to remove dried-on contaminants from the surface of the sensor. Gently rub the gel stick back and forth over the entire surface of the sensor until all of the dirt and grime has been removed.

  • Place the swab in a clean sink and fill it with enough water to cover it. Gently wipe away any grease or grime from the viewfinder with a wetted swab, making light circular motions. When attempting to remove the grit from the edges, don’t push down;
  • Use a clean cotton swab to wipe away any remaining filthy solution from the viewfinder until it is thoroughly dry;
  • Swab the viewfinder clean with a new swab until it is free of any grease or grime. The extreme edges are difficult to clean (at least without specialized equipment);
  • Remove any dust from the cotton swabs and dry the viewfinder with an air blower;
