How to clean a DSLR camera lens

Cleaning steps:

1. Blow with a blower

The correct method should be to first blow out the lens surface with a blower (also called an ear cleaning ball) This type of blower is sold in general photography stores, and the price ranges from a few yuan to dozens of yuan. However, be careful not to use self-service compressed air tanks as the pressure may be too high and the dust may be blown away. Do not blow directly into the gap of the lens with your mouth. Otherwise, a lot of saliva particles will be blown onto the surface of the lens, which will make it more difficult to deal with.

2. Wipe gently with lens cleaning cloth/lens paper

If the dust on the surface of the lens cannot be cleaned with a blower, we can also try to use a soft brush to clean the lens. Generally speaking, You can remove dust and other dirt. For stubborn stains, such as fingerprints, we have to use suede, lens cleaning cloth or lens paper combined with lens cleaning fluid to clean. When scrubbing, be careful not to squeeze the lens surface too hard, as the lens surface is covered with a fragile coating that can easily be wiped off by vigorous cleaning.

When purchasing lens paper, be sure to buy it from a regular professional photography store. Do not buy low-quality lens paper just for the sake of cheapness. When wiping the lens, never use hard paper, paper towels or napkins to clean the lens. Be sure to use tissue paper, and do not squeeze hard when scrubbing, because the surface of the lens is covered with a layer of coating that is relatively susceptible to damage. These products contain scratchy wood pulp, which can seriously damage the delicate coating on your camera lens, and you may regret it later.

3. Wipe lightly with a lens pen

Be sure to blow off the lens surface before using the lens pen to ensure there are no dust particles, and then press the lens pen vertically and clockwise from the center of the lens Rush out, and after one time, pay attention to blow off the lens toner that falls off the surface of the lens, then observe the effect, wipe again and blow again! Repeat 4-5 times and the lens should be as bright as new! Experts have said that any behavior of wiping the lens will damage the lens coating! Although the lens pen is a relatively safe tool, you should use it with caution. Always blow more and less than wipe the lens! The blower must be good, and if necessary, it must be equipped with a better UV protective lens.

4. Use lens cleaning fluid to remove stubborn stains (use with caution)

There is a lot of debate about whether to use lens cleaning fluid to clean the lens. Some inferior brand-name cleaning fluids will indeed damage the lens. Cause damage, so we recommend that if you can simply use suede and other tools to clean away stubborn stains on the lens, you don’t need to use cleaning fluid. When using it as a last resort, you must be careful not to use too much, and don’t get the cleaning fluid on it. Go outside the lens, because some cleaning fluids contain acetone, which can easily discolor the edges of the black lens. In severe cases, it can also cause deformation around the lens. Remember!
