There are many varieties of hunting binoculars for deer also.  If you keep your binoculars clean and dust-free, their lifespan will increase. 

How To Clean Binoculars Properly With 5 Helpful Steps

Here are a few steps that you can follow to clean the binoculars. By following these steps you can also clean your binoculars for under 200 to under1000$.

Five Steps To Clean Binoculars

Are you looking for the best ways to clean the binoculars and prevent binoculars from fogging safely without getting damaged? Here are some simple steps that you have to follow to clean your binoculars safely. 

Use Silica Gel To Clean Binoculars

1. Clean The Dirt

Using a blower or soft camel hairbrush on the lenses of your binoculars is the first step toward cleaning them. When you wipe the lenses, please avoid using your breath to fog them, as the moisture will trap dust particles on the glass.

If you use compressed air canisters, you might want to avoid them as well since the chemicals inside can destroy your lens coating. 

To eliminate dust and grit, you must prevent pressing them into the lens, which could cause scratches. Suction is best, but you are unlikely to accomplish this unless you have access to a vacuum cleaner.

It is more practical to use a puffer brush, which has a soft brush attached to a small rubber balloon. Available online and in-camera shops, these are inexpensive tools. 

Hold the binoculars up as the offending material falls away and blow a few puffs from a distance. Then sweep the brush in circular motions, and any dust or dirt will almost certainly have been shifted.

  You can use a soft-bristle brush instead of a puffer if you can’t find one. You can use a clean paintbrush or a make-up brush; the softer, the better, but make sure it’s clean; otherwise, you may worsen things.

2. Use A Cleaner

Gently moisten the lens with a cotton swab dipped in lens-safe solution in a circular motion. Never use window cleaner or eyeglass cleaner. Both of these products are too harsh for your lenses. What kind of moisture absorber do you have in your binocular case? Maybe silica gel? Don’t remove it, and it is doing a valuable job. 

Your binos will have cooled down while you were observing the skies. The cold surfaces of the lenses, including the outside, can cause condensation to form when you bring them inside. Any passing dust mole will adhere to your binoculars due to this moisture, and it may also promote fungi growth. 

To prevent premature deterioration of your binoculars, you should dry them before storing them. After allowing them to come to room temperature, wipe them down with a soft dry cloth. Pay special attention to the optical surfaces.

Afterward, store them with the absorbent in their case. If you want to recharge silica gel, put it in a low oven for an hour or two and let it dry. Silica gel can only absorb a limited amount of moisture. 

3. Use A Fiber Lens Cloth

Use this cloth only to clean the binocular lenses, and then store it in a plastic zipper bag between cleanings to prevent dust accumulation. Use only soft, smooth fabrics such as tissue, paper towels, or toilet paper because fibrous cloths can leave a scratch-causing residue.

4. Clean Binocular Body

Make sure dust is removed from the binocular body by blowing it with your blower. Using a damp cloth, gently wipe it with care so that it does not touch your already-clean lenses.  You should not use the same fabric as when you cleaned your lenses. The cloth you use for your lenses is delicate and should not be used for anything else.

5. Keep Binoculars On Cover

Most binoculars for stargazing come with carrying cases that keep them dust-free and protected when they are not in use. Don’t forget to cap those lenses and store them somewhere clean and dry.

Use a soft camel hair brush or compressed air to remove loose dirt from your lenses. You can then gently clean the lenses by spraying a cleaning solution on the lens cloth.

Keeping the binoculars dry will be easier if you put them inside a plastic bag with a desiccant inside. In this way, the desiccant will absorb the excess moisture and eliminate the cause of the fogging.

When your binoculars become cloudy or foggy on the inside, learning how to clean binoculars inside can be very helpful. Most often, this is condensation caused by an instant change in temperature. A leak in the camera could cause it.

To remove dirt loosened by the bristles of a lens cleaning pen, hold the binoculars upside down and use canned air to blow off the loosening material.

You should use canned air only if it provides short bursts of air and is not too close to the lens, as this can cause ice to form.

It’s going to take more than just water or a lens pen if there is evidence of spores such as tendrils. The most common remedies for cleaning fungus are alcohol, vinegar, dry air, and UV light. Click for Night Vision Scope here.
