How to maintain a digital camera

Stains on the lens will seriously reduce the image quality, appear spots or weaken the image contrast. Fingers touching the lens is inevitable, and dust and gravel will also fall on the optical devices.

Cleaning tools are simple: lens paper or fine tools with fiber cloth, lens brush, cleaning suit. Never use cardboard, paper towels or napkins to clean the lens. These products all contain scratched wood pulp, which will seriously damage the fragile coating on the camera lens.

When cleaning paper is not used, put the microfiber cleaning cloth into the original container to keep it clean. Microfiber cloth is very washable and can be washed with clothes regularly. Try not to use cotton T-shirts or other fibers, because coarse gravel may seep in. If you use a brush to clean the dust and debris on the lens, do not touch the hair on the brush with your hands or fingers. The oil on your skin will infect your hair and then stick to the lens.

Another way to clean the dust on the lens is to use the lens cover frequently. If your camera has a lens cover, you can fix it on the camera body with a belt, rubber belt or a "lens fixing" device.

Hot and cold weather can also affect the camera. If the camera was originally placed in an air-conditioned room and then immediately placed in a hot and humid environment, fog spots would appear on the lens and viewfinder. At this time, it is necessary to clean it with a suitable paper towel or cloth. If you bring the camera into the room from the cold and dry outdoor, you'd better put it in your bag to preheat it, and then take it out and put it in the house. And carefully hold the camera to see if it is "sweating". If you are sweating, you should take action at once. Professional photographer's advice: take a plastic zipper lock bag with you. In very humid or dusty climate, you can dig a small hole in the side to install the camera lens and put the camera in a bag to prevent fog, moisture and dust from entering the camera, which can prolong its service life.

Finally, don't put the camera in the back seat of a hot car. The car is like a stove, which will deform the plastic and damage the wires.

Many manufacturers will suggest that if you don't use the camera for more than two weeks, you'd better take it out, because the battery will leak and rot, sometimes affecting the circuit connection, making the camera unable to work normally.
