Cleaning Your Binoculars
Cleaning your bird watching binoculars can protect them from damage and increase their lifespan. Before beginning, read the maker or manufacturer’s guidelines that came with your binoculars for any specific instructions.
If no cleaning instructions are available follow the steps below, taking care to clean both the body and lenses using a gentle and delicate touch.
To clean the casing of your binoculars gently wipe the barrels, focus wheel, eyepiece rims and other parts of the binocular with a damp cloth. Be careful not to touch the lenses as you do so.
A can of compressed air can be used to blow debris from crevices around the focus wheel. Only use small puffs of air as a longer blast can create moisture that could get under the lenses.
To clean the binocular lenses begin by gently brushing away any loose dirt and dirt. You can use a small, soft clean paintbrush or makeup brush if you don’t have a special lens brush. Hold the binoculars upside down so any particles will fall from the surface.
You can also use compressed air to blow away dust but avoid breathing on your binoculars as the moisture from your breath can add to the dirt on the lenses
If your binoculars are waterproof, you can run the lenses under a gentle stream of water to rinse any dust away.
Use a wet cotton swab to soak up any remaining dust of visible particles but don’t rub it across the surface which can scratch the lenses. Use water or optics solution and avoid household glass cleaner which can degrade the lens coatings.
A lens cleaning pen or lint-free cloth can be used to wipe the lenses to remove smudges but do not apply more force than necessary.
When not using your binoculars cleaning equipment store it somewhere where it cannot get dirty or damp such as in a plastic bag.
