How To Clean Your Camera Sensor

Knowing the proper way to clean your DLSR and lens is essential to keep your equipment in good condition for clicks.

There are cleaning kits at affordable prices. The best one out there is the sensor gel stick.

For a more thorough cleaning, such as removing grease stains the lenses and dirt sensor will require liquid solutions and own brush to sensor.

The order given to clean your equipment is as follows:

  • Camera exterior (body and lens);
  • Lenses;
  • Sensor;
  • Caps, filters, cases and other accessories.

Camera exterior

The dirt from outside can get in more sensitive parts. Remove excess dust with the blower, wipe the corners buttons with a brush and finish with a clean cloth.

The lenses deserve special care because they can be damaged easily. First, use the spray in front of the lens. With a cotton swab or brush, clean the nooks and crannies. Finally, disconnect the camera lens to clean the back of the lens with the spray bottle.

To clean the “finger” spots, use only own tissues Microfiber (similar to “dusters” to clean glasses). If necessary, blow the lens with his mouth and apply slight movements on it with his handkerchief. The moisture “puff” facilitates the removal of dirt.

In most stubborn dirt, use specific liquids for lens cleaning. Before that, however, spray the air with surface to remove dust grains. Finally, clean the front and back of the lens, inside and out.

We stress the importance of spraying your lens with air before using a flannel. Even with slight movements, the dust grains may scratch the surface. And to ensure the protection of the front of the lens, choose the UV filter use. This filter is inexpensive, and although not its main function, the lens protects against accidental shocks, touch of fingers and dust.


* Clean the covers whenever possible;

* Please keep your cleaning accessories in clean places;

* Do not store your lenses in humid to prevent the proliferation of fungi on the inside of the lens;

* Be careful when using compressed air sprays. The high pressure and the substances contained in the air jet can damage your equipment;

* Do not risk your lens with homemade recovery methods, such as using toothpaste. Look for expert assistance.


DSLR Cameras sensors are also likely to have accumulated dirt on its surface. This is mainly for the exchange of lenses. The following are the consequences of the accumulation of dirt on the sensor.

To see if there is dirt on the sensor, shoot a smooth, clear surface, using the smallest aperture of your camera. The smaller the aperture, the more obvious will be the “shadow” caused by dirt.

Advanced cameras have automatic cleaning system. Just press the commands according to the manual. The camera D300 Nikon, for example, select the “Clear the sensor” option ( “Clean image sensor”) and then “Clear Now” ( “Clean now”). This model also offers an option where the sensor cleaning is done every time the camera is turned on or off ( “Clean at startup / shut down”).

If your equipment needs a more thorough cleaning, take it for assistance or use the camera sensor cleaning device we recommend. Do not forget to see if the sensor cleaning performed outside the authorized service violates the terms of the warranty.

To clean the sensor safely remove dust from the camera inside with the spray, holding the camera with the hole down, before exposing the sensor.

To expose the sensor, activate the “sensor cleaning”

If your camera does not have this feature, set the speed for 30 seconds, shoot and clean the sensor while the shutter is open. Make sure the battery is fully charged so that the camera does not close suddenly.

With the exposed sensor, use the spray again to remove dust from it. Make a new test to see if the sensor is clean.

If there is still impregnated dirt sensor, use a brush suitable for sensors. Spray the air with brush to clean it and make the bristles are charged with static. The static causes the dust sensor “stickiness” on the brush. Brush the top of the sensor after a single time.

You need a second hand? Then spray the brush again and brush the sensor in the manner indicated. Make a new image test.

If you shoot in humid environments often (waterfalls, beaches or in the rain), probably the sensor is impregnated with a type of dirt to be removed only with the use of solutions for sensor cleaning.

The “wet” cleaning method is the most risky. Apply the liquid in the swab, as indicated by the manufacturer, and lightly brush the top end of the sensor. Then, with the other side of the swab, brush the back from start to finish.

When in doubt or lack of materials needed, not risk. Take your equipment for service.


* Make changing lenses in a clean and dust in the air;

* When removing the lens, keep the body bore down to prevent the dust settled on the inside;

* Do not remove the lens from your camera without need, and when you do, put the lid on the lens and the camera body orifice;

Do not use ordinary cotton swabs to clean lenses and sensors;

Do not improvise cleaning solutions. You can cause irreversible damage;

* Inquire about the conditions of the warranty of your device at the time of purchase;

* Never apply cleaning solution directly on the sensor;

* The eyeglass lens cleaning should not be used in sensors, unless the manufacturer informs this.

Dirts in the mirror may appear in the preview image. This will not affect the resultadoda photo, but it can affect the functioning of the autofocus system in extreme cases. Anyway, this indicates that there is dirt accumulating inside the camera. Clean the inside with the spray air with the camera hole down.

Caps, filters, cases and other accessories.

The covers should be cleaned whenever possible, not to get onto your lens and camera. filters also deserve the same lens care because their dirt can contaminate the lenses.

Keep clean contacts, as in the case of batteries and flashlights. Remove dust and humidity to prevent the formation of rust. Keep tripods and other accessories free of dirt and moisture.

Sand, salt spray, dirt and dust accumulate easily inside backpacks and cases. Upon returning from a trip or external session, remove all content and make cleaning the inside.

The less time dirt and moisture is in contact with your equipment, the easier it is to remove them. It is best to clean up after the session, not when you’re shooting.
