When our camera lenses gather dust, the instinctive response is to blow on them to clear it. Unfortunately, this method is not only ineffective, but also harmful to the lens due to the acidic elements in your breath. DIY Photography shares a response from Nikon support that explains what you should do instead (you can also refer to the video above for a visual guide):
The ideal way to clean a lens is to use a lint-free lens cleaning tissue and a small amount of Lens Cleaning Solution. Avoid using any products with abrasives or solvents, and stick to Lens Cleaning Solution only.
Start by using a small blower brush to gently blow or brush away any loose dust or particles.
Then, apply a drop or two of cleaner onto the tissue (never directly on the lens) and wipe the lens in a circular motion, starting from the center and working outward to remove any spots or smudges.
If you don't have the recommended tools, a clean, dry, soft, lint-free cloth can be used to wipe the lens. Avoid breathing on the lens to fog it for cleaning, as the acids in your breath can harm the lens coatings. Instead, use the blower bulb, followed by brushing and wiping the lens in a circular motion starting from the center and working outward.
The same technique can be applied to clean the viewfinder eyepiece of Nikon cameras.
It may be tempting to immediately remove dust from your lens, but it's better to leave it alone for a bit than to try blowing it off. Instead, give yourself the eight minutes needed for a proper cleaning. Your lens will appreciate the extra care.
