There is dust in the lens of the camera. How to clean it?

If you want to clean, the correct method should be to blow off the dust on the lens surface with a balloon (also called an ear washing ball). This kind of balloon blowing is generally sold in photography shops, and the price ranges from a few yuan to dozens of yuan. However, you should be careful not to use the self-service compressed air tank as much as possible, because too much pressure may blow dust into the gap of the lens, and don't blow it directly with your mouth. In that case, there will be a lot of saliva particles blowing on the lens surface, which will be more difficult.

If blowing balloons can't clean the dust on the lens surface, you can also try to clean the lens with a soft brush, so that dirt and other dirty things can be taken out. For stubborn stains, such as fingerprints, we will use suede, lens cleaning cloth or lens paper with lens cleaning liquid to clean them. When scrubbing, be careful not to squeeze the lens surface hard, because the lens surface is covered with a fragile coating, which can be easily wiped off by hard cleaning.

You must go to a regular professional photography shop to buy lens paper. Don't buy inferior lens paper just because it is cheap. This kind of lens paper often contains a certain amount of wood pulp, which will seriously damage the coating on the lens of digital camera. At that time, you may "regret".

There are many arguments about whether to use lens cleaning liquid to clean the lens. Some inferior cleaning solutions can really damage the lenses. Therefore, we suggest that if the stubborn stains on the lens can be simply cleaned with tools such as suede, then there is no need to use cleaning solution. Use it as a last resort, and be careful not to use too much and not to touch the cleaning solution outside the lens. Because some cleaning solutions are acetone, it is easy to make the edges of black lenses fade and the lenses are seriously deformed.
