It's obvious that the cleaner the lens, the sharper your pictures will be. Dirt, dust, and fingerprints will degrade the image quality of even the finest optics. However, it's important to avoid using incorrect cleaning materials which can permanently damage your photo equipment. Used properly, the cleaning supplies in this kit are certified safe for use on your valuable digital and film photo-equipment and optics. The environmentally-friendly Hurricane Air Blower is a real dust-blaster. It's nothing like those tiny blower brushes which are capable of producing only a gentle breath of air. When you squeeze this deluxe Air Blower you get a focused gust of air that really pushes the dust off. Using the blower should always be the first step in cleaning your photo equipment. Use it to remove dust and dirt from the surface of your lenses before you attempt to clean them with lens tissue. Otherwise you may find that you are grinding grit onto the delicate lens surface and may scratch it. The blower may also be used — carefully following your camera manufacturer's instructions and exercising due caution — to clean the camera's image sensor. [Of course, it is recommended that image sensor cleaning be done only by those who are confident in their ability to do so.] A Lens Cleaning Cloth is included for convenient in-the-field cleaning. This kit also contains Lens Cleaning Liquid which is used to lightly moisten a sheet of Lens Tissue to aid in the removal of stubborn fingerprints and environmental pollutants from your lenses and filters . The included Cotton Swabs are very useful for caring for the exterior (non-optical) surface of your equipment. ♦ The Cameta Microfiber Cleaning Cloth is designed using the latest 21st Century technology to clean fingerprints, oily smudges and other contaminants from LCD monitors and lens optics quickly, safely and easily. ♦ Used regularly, this SLR Camera Care Cleaning Kit will keep your equipment sparkling clean.
