Keep Your Optics Looking (& working) Like New

Since your rifle optics do so much to enhance accuracy and target acquisition, it’s not the type of equipment that should ever be taken for granted. As with most things, regular cleaning and maintenance are the key to keeping your gear factory fresh.

No matter what your shooting discipline may be, properly maintaining your gun, its component parts and accessories is a must if you have any expectation of optimizing performance and consistency. It’s easy to let your cleaning routine slip, especially with something like optics. They just keep on doing what they do, right? Well, by neglecting these relatively simple tasks, you may experience reduced clarity and accuracy, an increased need for costly repairs, or even permanent damage over time. Equipment maintenance should be considered an ongoing priority rather than just a series of one-off responses to extreme situations or crises.

The Right Tools

Before jumping right into the cleaning and maintenance process, be sure to have everything you need to do the job right. Always be sure to avoid just grabbing something random within easy reach, especially when coming in contact with lenses. If the materials aren’t up-to-spec, you may end up doing irreparable damage to your equipment.

Essential items would include:

• Lens pen to safely remove smudges and fingerprints
• Soft bristle or blower brush to remove loose debris
• Compressed air to blow away dust before wiping
• Lint and scratch-free microfiber cloths or tissues for wiping lenses
• Cotton swabs for precision cleaning of tight spaces and turret knobs
• Lens cleaning solution for removing grime
• Hex wrenches for precise scope component adjustments and disassembly

Cleaning Tips

Routinely removing dust, dirt, fingerprints, and residue will help to keep your optics operating  optimally. Here are some tips for properly cleaning your rifle scope:

 Know Your Optics

Different types of rifle optics, such as scopes, red dot sights, and holographic sights, may require specific cleaning methods. Familiarize yourself with the manufacturer’s guidelines and recommendations for your particular optic. Some scopes may have coatings that require special care, and using the wrong cleaning agents can cause irreparable damage.

Start by Removing Loose Debris

Before applying any cleaning solution, use a blower brush or compressed air to remove loose dust and debris from the lens surface. This helps prevent scratching during the cleaning process.

Use Lens Cleaning Solution

Apply a small amount of lens cleaning solution to a soft cloth or lens cleaning wipe. Do not apply the solution directly to the lens to avoid excess liquid getting into the scope. Since most optics are usually coated, use only wipes that are recommended for such surfaces.

Gently Wipe the Lens

Wipe the lens gently in a circular motion, starting from the center and moving outward. Use light pressure and repeat as needed until the lens is clean. Avoid using excessive force, as it may damage the lens coating.

Address Stubborn Stains

For stubborn stains or fingerprints, use a lens pen or a lens brush with a cleaning tip. These tools are designed to safely remove smudges without scratching the lens.

Clean & Maintain the Exterior

Wipe down the exterior of the scope and mounting system with a clean, dry cloth to remove any moisture, dirt or residue. Be sure to be extra diligent if you’ve been shooting in wet or dusty conditions, or if there has been any exposure to salt water. Always be cautious around adjustment turrets and other sensitive areas. Using cotton swabs is a good way to clean between any gaps or hard-to-reach areas.

Beyond everyday care, there are a number other things that you can do to help keep scopes performing like new:

• Inspect the rings, bases, and any other components securing the optic to the rifle. Tighten any loose screws and ensure the mounting system is secure.
• Snug loose turret and focus knobs using hex wrenches
• Lightly lubricate moving parts like turrets and zoom rings using gun oil to prevent binding

It is not recommended that you disassemble your scope for inspection or maintenance unless you REALLY know what you’re doing. You may want to seek out the help of a professional service for things such as interior fog issues, replacing O-rings, re-application of coatings or the replacement of lenses.

 General Hints & Tips

Here are some randoms for consideration:

Regularly inspect your optics for signs of damage or excessive wear and address any issues promptly.

Avoid over-cleaning your optics as this may damage or remove lens coatings and can affect image quality.

If you frequently shoot in dusty or humid environments, consider investing in lens covers or caps to protect your optics when not in use.

Handle optics with clean hands and avoid touching the lenses directly to minimize the transfer of oils and fingerprints.

Before you attempt any cleaning or maintenance, be sure to allow time for your equipment to acclimate to the ambient temperature (ie. moving from a cold environment to a warm one or vice versa)

Minimize breathing directly onto the lens. Moisture from your breath can contribute to fogging. Instead, use other methods such as warming the optics with your hands.

If your optics have a battery, remove it during long periods of inactivity to prevent leakage. Check and replace batteries as needed.

Always carry your equipment in a case for added protection.

Storing Your Optics

Proper storage helps prevent damage and moisture buildup, reduces the risk of fogging and can extend the lifespan of your equipment. When not in use, store your rifle with optics in a cool, dry, well-ventilated place and avoid extremes in temperature or exposure to direct sunlight for long periods. Store your rifle scope in a protective case or breathable pouch when not in use to prevent exposure to dirt, dust, and potential damage. Adding moisture-absorbing desiccant (silica gel) packets to your cases, bags or storage cabinets is also a good idea.

Regular cleaning and maintenance are essential for preserving the clarity and accuracy of your rifle optics. By following these guidelines, you can ensure that your equipment remains in top-notch condition, providing reliable performance when it matters most.
