How To Keep Your Scope From Fogging Up

Condensation or fogging up on a riflescope is a big issue. Fogging within a riflescope is a completely different story. Temperature fluctuations cause moisture to accumulate on the exterior of your scope lenses. Finding the interior of your scope murky indicates that the scope has been damaged. The seals are most likely compromised, and the nitrogen inside the scope has spilled.

There are various methods for dealing with outside condensation on your riflescope. A little planning ahead of time is generally enough to keep moisture from forming on the glasses and weapon. If there is moisture within your scope, the only permanent solution is to mail it back to the manufacturer.

It is not uncommon for moisture to form on anything when exposed to the damp air outside. Condensation usually occurs when you move your rifle and sight from a cool, air-conditioned environment to a warm, wet environment outside.

It’s a good idea to keep your gun in your residence where it can stay cool and dry. Taking the chilled rifle out on a hot day with high humidity might cause moisture in the air to pool on the weapon, especially the cold lenses. 

There are numerous solutions to the fogging problem on riflescope lenses. Some of these methods may violate your scope’s warranty, so use caution.

Become acquainted with your rifle and scope

The temperature differential is the most common cause of moisture accumulation on the exterior of your sight and weapon. Moisture will gather on the rifle and sight as it cools if the scope and rifle are substantially warmer than the chilly outside air. Condensation occurs naturally. You may take many methods to protect your rifle and sight from fogging up or accumulating moisture.

• Allow your rifle and sight to acclimatize to the outside temperature for a few minutes. Bringing a heated rifle and sight from home or the automobile into a chilly setting nearly always results in moisture collection.
• Keep your cased rifle and sight in the coldest area of your vehicle if you must travel to your hunting spot. The plan is to gradually adapt the rifle and sight to the temperature during the journey.
• When you are at your hunting location, open the rifle and scope case and allow them to acclimatize to the temperature. If your scope has lens covers, remove them.
• Breathe away from your chilly scope lenses. Warm breaths may be an issue with scopes with different eye reliefs. A chilly scope lens will almost immediately condense the humidity in your breath on the glass of your scope.

Taking Care of Your Scope Lenses

Many hunters swear by various solutions to keep condensation from forming on the lens of their riflescopes. Some of these goods are dubious and may violate your scope’s warranty.

Can I Get the Moisture Out of My Riflescope?

The most often recommended way of eliminating inside moisture is to warm the scope. This procedure is not recommended for more costly scopes.

Which lens caps are appropriate for lenses?

Lens caps are useful for protecting the lenses of your riflescope. Flip-up hats are our preference. Some photographers like to use a bikini top lens cap. Whichever you select, make sure to use them often to safeguard the lenses and their coatings.

Which instruments are necessary for lens cleaning?

It is preferable if you clean your lenses with the correct equipment. Only a decent lens brush and specialist lens microfiber cloths should ever come into contact with your riflescope lenses. Do not spray anything, especially home window cleaners, on your riflescope or its lenses. These products include substances that can harm or remove lens coatings and harden seals, leading them to shatter.

Conclusion

Condensation on the exterior of your rifle and sight is normal. Many times, a little forethought and planning can assist to lessen or avoid these issues. Outside condensation should not influence the performance of your scope if it is in excellent condition.

Moisture within your scope is a far more dangerous problem. In most situations, a fogged lens on the interior indicates scope damage. The only long-term solution for this situation is to return to the manufacturer for repair or replacement. We hope you found this advice on how to keep your scope from fogging up useful.
