First of all, you should get the sensor exposed. Once the whole sensor becomes visible, you should clean the lens with the gel stick. Then you should clean the dust off the gel using the adhesive paper that comes with the gel stick. Remember: don’t make a rush when cleaning the camera. You don’t want to drop the camera accidentally.
You can use the gel several times repeating the process over and over again. Once you are done, you should turn the camera off, install the lens and set the aperture to f/32. Now, take a photo of a white wall or a white piece of paper. If the picture is free of any spots, the lens is clean.
Usually, sensor gel sticks should not be used in a room with a temperature lower than 40F. The ideal temperature is 70F if you want the best performance. Using the product in too low or too high temperatures will not give you the best performance. In worse cases, you may end up reducing the shine of the sensor, which will adversely affect the image quality. Therefore, you may want to check the temperature of the room first.
Since the stickiness of the gel varies based on the coating technologies applied on the sensor filters, we suggest that you don’t use one sensor gel stick for cleaning the lens of different cameras, as one shoe can’t fit everyone.
Normally, the cleaning product can be used on all digital cameras that come with interchangeable lenses. The good news is that most camera manufacturers have cameras that have interchangeable lens.
Some mirrorless cameras feature a coating technology that allows the gel sticks to leave behind some residue on the sensor filter surface. As a result, you will need to clean the sensor thoroughly. You should use the right type of sensor gel stick for cleaning these cameras.
Cameras that don’t come with a mirror are not easy to clean. Therefore, it’s a lot better to go for a camera that can be easily cleaned. A lens that is not clean won’t allow you to take high-quality pictures, as the quality of the pictures depends largely on the clarity of the lens or sensor. Therefore, cleaning the lens with a quality cleaner is highly recommended.
