Preparing for cleaning

Before you begin the cleaning process, prepare your cleaning area. You will need a steady work surface, such as a table or countertop, that is free from dust and debris. You may also want to use a mat or cloth to protect the lenses from accidental scratches.

You’ll also need a few specialized items to do the job properly. Gather soft cloths for wiping down and drying the binoculars, lens cleaning solution designed specifically for optics, cotton swabs for getting into tight crevices, compressed air for blowing away stubborn dust particles, and professional quality lens-cleaning wipes if possible.

Additionally, you will want to familiarize yourself with your binocular model before proceeding with any type of cleaning — especially if it’s an older pair of binoculars that has not been used in some time. Make sure you are comfortable working with all of the parts and pieces before delving deeper into the actual cleaning process.

Gather necessary materials

  1. Gather necessary materials: In order to properly clean binocular lenses and barrels, you’ll need a few basic materials. Some of the items that you must gather beforehand include microfiber cleaning cloths, dry soft cotton cloths, optical cleaning solution, eyeglass screwdriver, air blower, lens paper and lens brush. All of these items should be easily acquired from optical stores or online retailers; however it is recommended to avoid buying non-optical grade products as they can damage your binoculars.
  2. Cleaning the lenses: Before starting the cleaning process, make sure your binoculars are switched off and all the caps are removed. Use your blower to remove loose dust and particles from the lens surface before using any liquid cleaning agent on them. Subsequently, apply optical cleaning solution on a microfiber cloth and rub it in circular direction on both surfaces of each lens until spots are gone – make sure not to allow excessive amounts of fluid between lens ridges as this could cause them to dry in an undesirable manner. Finally use a dry shirt made out of pure cotton material though remove fluids if necessary with lens paper or tissue paper instead of directly using it for manual wiping process.

Choose a clean, well-lit workspace

It is important to pick a workspace that is free of dirt and dust to avoid getting it on the binoculars during cleaning. It should also be well-lit since you will need to clearly see the lens surfaces while you clean them.

Choose a quiet area in your home, then spread a lint-free cloth or towel on the table or on the floor. This will provide a soft, nonabrasive surface on which you can lay your binoculars while cleaning them. Your chosen workspace should also have good airflow, so open up windows to create air circulation in the room.

Remove any debris or dirt

Using a soft brush, like a makeup brush or an old toothbrush, to gently remove any dust and debris that may have collected between lenses or the body of your binoculars. If stubborn bits of dirt remain use a non-abrasive cloth for cleaning. This cloth should have been provided with you binoculars, but if yours didn’t come with one then use a lint-free microfiber cloth. It is important not to use paper towels as they can contain tiny particles of wood dust that can harm the lenses on your binoculars.

Gently wipe and polish lenses using swirling motions until all dirt is removed. Take extra care when wiping and polishing the objective lens (the larger lenses connected to the objective tabs) as this lens cleans best when polished lightly without pressure. Once your cloth is saturated with dirt and oil, it can be changed out for another clean piece of cloth so that you don’t transfer debris back on to the lens surface.

III. Cleaning the lenses

Cleaning the lenses of your binoculars is one of the most delicate processes in binocular maintenance. The most important thing is to take utmost care and use the correct technique and materials. Depending on how your lenses have aged, you can choose from either air or liquid methods for cleaning, although dust should always be removed with a soft brush or by blasting with compressed air.

Unless you are using specialized cleaning tools, avoid touching the lenses directly as this leave smudges that can blur and alter overall image quality. If necessary, use lens cleaning paper which removes dirt without leaving scratches on the surface of the optics.

Small bits of dirt such as pollen can block illumination as well as degrade image resolution by diffracting incoming light. The same goes for dried liquid blobs caused by rain or condensation on the lens surfaces – this usually requires specialized lens cleaners that gently remove all kinds of debris that are otherwise difficult to remove through regular cleaning techniques. You can also use a product specifically designed for this purpose – it comes in the form of a gel that is applied sparingly to the lens and wiped off gently with a tissue in long, smooth strokes until it dries out completely; repeat if necessary.

Use a soft brush to remove debris

A soft brush is the ideal tool for removing debris and dust from your binoculars. Use a disposable makeup brush or dry cloth to lightly brush the lenses, making sure to work the bristles in small circles to avoid scratching the surface. Take extra care when cleaning around the lens and eyepiece rings.

You can also use a can of compressed air or vacuum cleaner with an adjustable nozzle attachment to remove debris from hard-to-reach areas. Make sure not to use a vacuum cleaner on exposed lenses as it could cause scratches.

Apply lens cleaner

To start to clean the lenses, hold your binoculars firmly in the palm of one hand. Dip a lens cleaning cloth into the solution and gently rub across the lenses. Be sure to not press hard as this could permanently damage your binoculars. Clean in a circular motion, covering each lens twice. Use a separate area of the cloth each time you begin so that no dirt from earlier passes is present when you finish.

You may also want to use a moisture-free cleansing brush to reach any crevices on the surface of the lens. For best results, try blowing air onto the lens prior to cleaning with a brush or cloth for further cleaning power and clarity of vision.

Wipe gently with a microfiber cloth

Gently wiping the lenses down with a microfiber cloth is the final step in cleaning your binoculars. A soft microfiber cloth is required, as larger fibres may damage the intricate workings of your optical instrument. Make sure to move the cloth in a circular motion starting from the centre and radiating outward – this ensures no residue is left on any surface of your binoculars.

Optics experts recommend cleaning binoculars with a new microfiber cloth every week or two, to ensure that any residues are removed which can cause scratches or distort your view if left over time.


Cleaning your binoculars on a regular basis is essential for preserving its image quality and keeping it fully functional. Be sure to use the right cleaning tools to avoid any damage and gently brush away any dirt or debris from the exterior of the binoculars. Use only in-resistant lens cleaning fluid and wipes specifically made for optics cleaning, and never use alcohol, ammonia or other harsh tools.

After each use, wipe down the outer lenses with a soft microfiber cloth to remove any fingerprints or smudges.

Regular cleaning and inspection of your optics will go a long way in increasing the lifespan and usability of your binoculars. A few simple steps can easily be done to maintain your binoculars at home.

Start by wiping dirt, dust and debris from the external lenses of the binoculars using a lens cleaning cloth; or you can use compressed air. When using the cloth, start from the center and slowly work outwards to wipe away dirt or smudge marks. For stubborn smudges, apply some lens cleaner to a microfiber cloth before wiping off the lenses. Once this is done, examine for minor scratches on the lenses’ coatings that require repairs or replacements depending on their severity. If nothing is found, move on to inspecting and lubricating the internal mechanisms which include hinges, prisms and focusing pieces.

One common mistake made by most beginners is soaking their binoculars in water when cleaning it; however this could potentially damage some parts that are not waterproof like eyecups or o-rings inside the tubes; thus care must be taken when cleaning with water only as advised by most manufacturers’ manuals. It’s therefore always best to start hand-cleaning with a dry cloth first followed lubrication if necessary; so keep your hands dry while engaging in such activities!

Overall, proper care for your binoculars can extend its life really long into many years and have yours performing like new each time you get them out for use!
