Its very important to clean your binoculars because a lot of stuff gets in there when you are out on your outdoor adventures. So, removing the dust and debris that gets stuck in there is important. But it is also worthwhile mentioning that you don’t want to clean your binoculars very often.

The reason is that the lenses are coated with a layer reflective and a protective coating or more coatings. Most high-quality binoculars are coated anyway. What this lens coating does is to allow a greater amount of light through the lenses to create clearer, brighter and sharper images.

Step 1: Blow of Dust and Debris

Step 2: Use a Lens Pen

This step is to help get more dust off the lenses. This brush is very soft and with the binoculars in the same position as step 1, use the lens pen to brush the lens surfaces. This will remove most of the dust on the surface. Once you are sure the dust has been removed. then move to step 3.

Step 3: Use Microfiber Cloth and Lens Cleaner

Use the cloth in conjunction with the lens cleaner. Spray the cloth a little with the cleaner and gently wipe the lenses off with the microfiber cloth. This will remove water spots and things like that. Do this to both lense by spending some minutes wiping the surfaces. Do not wipe or press too hard on the lenses.

If for any reason you don’t have the cleaner you can use lens wipe to clean your lenses surface. It’s good enough.

Step 4: Repeat Same Process for the Eyepieces

Whether you are using your eyecups or not, once in while dust can also find their way into your eyepieces. So its good to get them off as well. So just simply repeat the same process above and you are good to go.

Be gentle.
