How to Properly Clean your Binoculars

Proper cleaning of your Uscamel binoculars guarantees that you will enjoy them for a long time. What many people don’t know is that mechanical abrasion can damage the optical surfaces if they are cleaned incorrectly. This is quickly reflected in the image quality. In this blog post we give you tips for correct cleaning.

Deposits

Over time, a thin film of grease builds up on the lenses of the binoculars, for example when you touch them with your fingertips. This alone does not damage the optical surfaces. However, a microscopic layer of crystalline dust usually settles on this lubricating film, which is invisible to the naked eye. If you now try to remove the greasy film from the optical surfaces using a cloth, the circular movements will have a similar effect to sandpaper on the tempered surfaces of the binoculars.

The coating guarantees that as much of the light hitting the glass as possible reaches your eye – and is not reflected and thus “lost”, so to speak. The multiple layers of coating are wafer-thin. Repeated improper cleaning can damage them and permanently affect your viewing pleasure. Scratches caused by mechanical abrasion cannot be “polished out”. In the worst case, you have to replace the affected components at great expense.

What is the best way to clean deposits from your binoculars?

To clean, first use a fine brush, the bristles must not be too coarse, and use it to dust the surfaces thoroughly. Once the surfaces have been freed from the layer of dust, a microfiber cloth is used. Breathe on the surfaces lightly and then wipe them off with the cloth. Do this carefully and avoid circular movements. It is best to keep the cleaning cloth in a dust-proof bag to avoid dust here as well.

Fungal Infection

Fungal infestation inside the binoculars is usually impossible with high-quality, nitrogen-filled and waterproof models. However, if the binoculars are not stored properly, fungus can form on the outside of the optics. Particularly warm room temperatures and deposited layers of dirt and fat give fungi a good basis for thriving. Therefore, keep the binoculars in an airy place and clean them thoroughly before not using them for a long period of time.

To allow the film of moisture on which the fungus has spread to evaporate, you can expose the binoculars to direct sunlight for a while. Then clean the optical surfaces with water, glasses cleaning agent and a microfibre cloth.

What are General Binocular Care Tips?

Finally, it should be said that binoculars are of course not made to lie in a showcase with a polished finish. Dirt is sometimes unavoidable, especially on long hikes. They are also not a concern if you clean your binoculars gently. For a crystal-clear view at all times, please note the following tips:

Touch the lens openings of your binoculars as little as possible.
After each observation, replace the protective covers.
To remove deposits, use a fine-bristled brush.
Microfibre cloths remove grease and water stains (you can also use eyeglass cleaner if necessary).
Store the binoculars in an airy, not too warm place.
Thoroughly clean your binoculars before long periods of non-use.
