Continue reading to learn about the best ways to clean your binoculars and what techniques and products to avoid in order to prevent damage to the lenses and casing.

Read the User Manual

Often, when most people buy a new product, they usually skip reading the user’s manual. But doing so with your new binoculars can lead to serious damage, especially if they have special coatings on the lenses. So, before you even try one of the cleaning methods we’ve included here, make sure you read the manual from cover to cover. Most often, binoculars that do have coated lenses will come with special instructions and product recommendations in regard to what is and isn’t safe to use.

Cleaning the Exterior

the binocular’s housing is often subjected to plenty of use and abuse. It’s exposed to dirty hands, bad weather, and it can take a serious beating during transport or if you accidentally drop them. However, the durable rubber armor casing you’ll find on many top of the line models can actually provide quite a bit of protection against serious damage, and it’s what helps to lengthen the life of your binoculars. Cleaning the casing is much easier than cleaning the lenses and simply requires a damp cloth for a fast wipe down. This should be done prior to cleaning the lenses.

What Can Ruin Your Binoculars

Breathing and rubbing on the lenses can lead to frosting the glass. With the dust, the main ingredient is silica, otherwise known as very tiny rocks. Unfortunately, silica is harder than glass, so if you rub the dust across the lens, you can actually cause microscopic scratches in the lenses and ruin the thin layers of lens coating. You may not even be able to see the scratches, because they’re so small, but they can still scatter light. Over several weeks or months, the lenses will slowly cloud up.

So, before you start rubbing the lenses, make sure you get the dust off first.

The Right Way to Clean Lenses

Buy a lens cleaning pen. These are specifically designed to handle the sensitive surface of lenses, including delicate coatings. It will allow you to gently remove any dust from the surfaces of the lenses.

Another option is using a can of compressed air. Never use your breath because it contains tiny drops of water that can result in spotted lenses.

Cleaning Solution or Water

For the next step, take a Q-tip and lightly moisten it with a lens cleaning solution or water. This will help to remove any remaining dust from the surface of the lenses. If you have waterproof binoculars, you can run them under the faucet. Never use a cleaner that’s designed for cleaning windows or eyeglasses since it can damage the delicate coatings on the lenses.

Wiping the Lenses Clean

Once the dust is completely gone, you can then use a special microfiber lens cloth or lens tissue.

Never use toilet paper or paper towels since they’re too abrasive. They also usually contain wood fibers that can scratch the surface of the lenses.

When you wipe down the lenses, make sure you’re very gentle.

How Often Should I Clean My Binoculars?

Your binoculars should be cleaned whenever you notice a change in image clarity. Most binocular owners can agree that they should be cleaned right before you use them, each time. This can help to prevent a serious buildup of dust and dirt, which can cause damage to the lenses if not removed promptly.

Obviously, image clarity is a big deal, especially when it comes to birding binoculars. If you notice that there’s a significant change in clarity, even after you’ve cleaned the lenses, then your binoculars may need to be professionally serviced. This can be caused by a shift in the lenses or prisms. To learn more about birding binoculars and how they work, click here to read our birding binoculars buyer’s guide.

What Do I Need for Birdwatching Aside from the Binoculars?

Can I Use Any Type of Binoculars for Birding?

But you’ll soon realize that these binoculars don’t have the type of clarity it takes to properly identify a bird. On average, you’ll need birding binoculars that offer at least 8x magnification.
