Your lenses will be delighted if you care for them tenderly and probably it might be nice for you as well if you occasionally clean them from dust, grease stains and other kinds of dirt that a lens accumulates in your everyday use. There are a lot of ways and means to take in order to keep your lenses and especially the front lens in mint condition. This site offers some quick how to, quide lines and a video tutorial to keep your lens as new and we also tell you which products to use.
2. Gently brush away the remaining dust and / or dirt with a Cleaning Brush.
3. Soak a Micro Fiber Cloth with Cleaning Solution and clean the lens in a circular motion.
Do not clean your lens too often
A mistake often made is using the Micro Fiber Cloth before you blow away dust and dirt, which can result in dragging around dust particles and scratching the lens. The fact that a lens and the front lens gets a little dusty at times is normal, it is difficult to avoid but do not clean the lens too often (and do not use alcohol etc) since a perpetual rubbing and cleaning can damage the lens and its surface treatment (coating).
PS. Be careful when changing lenses
When changing lenses (in order to clean the backside of the lens, as seen in the video above) you open up and expose the inside of the camera. The camera will then be open for dust particles to enter and in case the sensor of the camera is effected by dirt and stains, this can have visible impacts and effects on the image and any dirt on the sensor can be difficult and tricky to remove without consulting a camera repair shop. Because of this it is important that whenever you change a lens, try to be as quick as possible and to the greatest extent possible, do not change lenses in dusty environments.
