How to clean the camera lenses?

The steps and methods for cleaning camera lenses are as follows:
Using air blowing: First, use air blowing (also known as blowing balloons) to blow off large particles of dust on the surface of the lens. Blow the air blowing port downwards several times to remove the dust inside. Then hold the camera or lens in hand, tilt it downwards so that the air outlet is at a 45 ° angle to the lens, and blow away the dust on the surface of the lens. ‌
Using a lens pen: If air blowing cannot remove dust from the surface of the lens, a lens pen can be used. Lens pens usually have a soft bristled brush on one end for removing dust, and a carbon chalk on the other end for wiping grease and stains. First, use a soft bristled brush to remove large particles of dust, and then use carbon chalk to wipe from the center of the lens outwards in circles. ‌
Use a grease free cotton swab: For stubborn stains, a grease free cotton swab can be used in combination with high-purity alcohol or cleaning solution for cleaning. Tilt the cotton swab at an angle of about 60 °, gently wipe the surface of the lens from left to right, then wipe from right to left, and finally use a cotton swab that has not been soaked in alcohol to gently scan the lens and absorb any remaining alcohol.
Use sensor cleaning stick: For CMOS sensors, a sensor cleaning stick can be used. After dipping in an appropriate amount of cleaning solution, wipe the CMOS from left to right with even force. After wiping once, flip it over in the same direction and wipe it again. If the stains are still not removed, it is recommended to seek professional assistance to avoid irreversible damage to the sensor. ‌
Attention:
Avoid using regular tissues, towels, or clothing to clean the lens, in order to avoid scratching the lens or leaving fibers. ‌
Cleaning should be carried out in an environment with less dust and air flow to reduce the intrusion of dust. ‌
Static electricity will attract dust, so when using the camera in a dry environment, you can use an antistatic spray.
By following the above steps and precautions, it is possible to effectively clean the camera lens, extend its lifespan, and maintain clarity.
