Transparent coated on lens elements that helps reduce reflections and flare to improve image contrast.
Lens Coating A layer or multiple layers of thin, anti-reflective materials applied to the surface of lens elements to reduce light reflection and increase the amount of transmitted light.
Lens coatings have two drawbacks. First, they must be kept scrupulously clean at all times, as oils and dirt interfere with the way they work. Fingerprints are extremely obvious on coated glass.

Fingerprints can be very harmful to the lens coating and should be removed as soon as possible. Use a lens cleaning cloth (or roll up a piece of photographic lens cleaning tissue and tear the end off to leave a brush like surface).
In the years before lens coating was generally practiced this had advantages for contrast and resistance to lens flare.
Ethanol and cotton flannel are recommended by Nikon, so I doubt that they would harm lens coatings if used in moderation.
Next, inspect the front element by tilting it an angle, so a strong light reflects from it, revealing the lens coating. Look for a consistent finish and no marks scratches, swirls, or places where the coating has disappeared.
Thank you for the instructions for cleaning lenses.But I have some ideas like this: is there any risk for promoting molds growing and for damaging the lens coating?
Thank you very much

means they have a wider aperture, making them better for low-light situations. Pro zoom lenses will also retain this aperture throughout the zoom range. Pro lenses are also more likely to be be built better - more rugged, with better lens coatings ...
