The Best Way to Clean a DSLR Lens
Cleaning a DSLR lens can seem a daunting task to the new camera owner, especially if your previous experience is limited to point and shoot cameras. Don't worry, taking care of your DSLR lens is simple, and there are a few easy but important tips to keep the lens clean and safe. An inexpensive UV filter and a lens hood can keep dirt and dust from the lens glass, and microfiber cleaning cloths and soft brushes take care of the rest.
Filters and hoods
The first and best step to cleaning your lens is prevention. Any steps you take to keep your lens clean and avoid having to touch the surface are well worth it. Attaching a UV filter to the lens will keep dust and oil from ever getting on the lens glass, and protect from bumps and scratches. You're also saving wear and tear on the sensitive lens surface by cleaning the filter, not the lens. Another tip is to use a lens hood. These simple devices are made to cut down on lens flare in bright light, but are an invaluable tool for protecting the end of the DSLR lens from damage. If you use your DSLR outdoors or hang the camera around you neck for extended periods, get a lens hood. Next time you bump the camera lens on a door or rock, you'll be grateful.
Blowers and brushes
A blower is your first step in cleaning the lens or filter surface of dust, and is readily available at any good camera store. These are also used to clean the interior of cameras, especially the sensor, and work great as a quick clean for the lens. Use the blower to blast any dust from the lens with forced air without having to touch the lens surface. Be sure to squeeze the bulb on the blower a few times before using on the lens to get rid of any dust in the nozzle. To remove stubborn dust and grit, use a soft camel's hair brush to gently sweep off any particles without scratching the lens or filter surface.
Cloths and cleaners
To clean the lens or filter surface of oil and smears, use a lens tissue or microfiber lens cloth. These will not scratch your lens surface and are good at removing oil and fingerprints. Add a drop or two of alcohol-based lens cleaning fluid to the cloth or tissue and gently clean the lens in a circular motion. Use the lens tissues only once and then throw away. Keep clean microfiber cloths on hand, and use them also only once before washing. Don't risk rubbing grit hidden in a dirty tissue or cloth over the lens surface. Another handy method is to use a lens pen. These retractable tools have a lens pad with solution on one end and a brush on the other, and are great for use in the field and for quick touch-ups. Always remove dust and particles first with a brush or blower before touching the lens with a tissue or cloth.
