Why Does Moisture Appear Outside My Rifle Scope?

0. Condensation

Condensation

Condensation outside your gun and scope is a natural phenomenon and should come as no surprise. Any item exposed to moisture in the outdoor air will have water on the surface.

One of the main reasons this problem occurs is the temperature difference between the two areas.

Many people have a habit of storing weapons and lenses in warm storage. After taking them out for use, the cold can cause condensation. Fog also occurs when you leave the lens in a cold air area outside in a hot, humid environment.

Low-quality and cheap lenses are also more likely to become blurred after a period of use.

Since this is a natural phenomenon, it won’t be easy to prevent them entirely. A helpful piece of advice is to prepare yourself and explore some of the remedies below.

How To Keep Rifle Scope From Fogging Up?

How to stop rifle scope from fogging up?

There are a few ways to prevent your rifle’s lens from staying clean and clear. Let’s find out more in the section below.

Using High-quality Scopes

Using high-quality scopes will minimize the risk of blur during your hunt. Low-quality lenses are sometimes the cause of condensation problems.

Budget is always a sensitive issue when you go shopping. Most of us are often attracted to low-priced products without knowing that everything has a price. Buying low-quality lenses will cause focus problems and a limited field of view when hunting.

You will need to equip yourself with a high-quality lens for professional hunters. It helps increase performance when hunting.

Another plus when choosing high-quality lenses is that you won’t have to spend extra money on anti-fog gear. This type of product usually already comes with anti-fog technology and high-quality materials.

In the long run, they are the more budget-friendly option.

Avoiding Cold And Rainy Weather

External factors such as weather and humidity are the leading causes of fogging.

The first thing you need to keep in mind is carefully choosing a hunting location. Avoid environments that are too wet or cold. In winter, there is often dew. In the rainy season, there is rain that can increase the humidity in the air.

We recommend that you store your rifle scope in a warm and dry area, such as a garage or car. If you must drive to the shooting range, keep the device in the coldest place, like the trunk of your vehicle.

After arriving at the location, open the lid slowly to allow the device to acclimate to the outside temperature. If your lens has a cap, flip it open.

Wearing Face Mask

The optic is usually in very close contact with your eyeballs, nose, and mouth. So, they are effortless to fog up when you exhale and breathe in.

In wet and cold conditions, take care when breathing.

One of the best ways to prevent this is to use a mask. This method is very effective but causes some inconvenience in the long run as it makes some people feel short of breath. If you have the same problem, consider practicing breathing through your nose.

Breathing through your nose allows air to flow more easily and prevents condensation directly on your lenses.

Using Anti-Fogging Treatments

The most common method is to use anti-fog tools. You can find a variety of models and features in the market. Each type has its characteristics, so consider carefully to make the best decision.

To understand the method of cleaning rifle scopes, please refer to the video below.

Microfiber Cleaning Cloth

Microfiber cloths

Microfiber cloths are the most suitable device for cleaning your optic. Usually, they will come with the lenses when you make a purchase. Use this kit regularly to wipe and clean the lens.

The advantage of this towel is that it is affordable, thin and light, easy to use and carry. You can also use it to clean your eyeglasses.

Keep plenty of these towels in your tool bag to change as needed for professional hunters.

Cat Crap Lens Cleaner

Cat crap lens gel and microfiber cloth are a great combination. You can use them to clean glass surfaces thoroughly. In addition to this gel, there are many similar choices on the market.

Touch Care Cleaning Set

If you don’t want to use gel, consider using a spray bottle to clean your optic lens. However, you must not spray the solution directly onto the surface.

Direct spraying of cleaning solution onto glass surfaces may result in internal condensation. This problem is quite severe, and sometimes you will have to replace your lens.

Spray the cleaner on a paper towel or soft cloth, then wipe the surface in a circular motion.

You can also use optic cleaning liquids instead of sprays. Although they are pretty bulky if you want to carry them often, the cleaning ability of this solution is quite effective.

Lens Cap

Don’t leave your lenses open all the time unnecessarily. A good piece of advice is to close your scope tightly. It will help prevent moisture and fog from reaching the surface.

Only remove the cover when you want to use your device. It is best to remove it first for a second and wait for the temperature on the glass surface to equalize with the outside.

Why Does My Scope Have Moisture Inside And How To Avoid It?

3. Riflescopes

Riflescopes

If moisture collects on the inside of your rifle’s lens, the most likely reason is that the seals on the tube have been damaged. When the seals fail, the nitrogen inside leaks out and allows moisture to get inside.

Condensation inside the lens is usually a sign that the user can no longer use the device.

You can contact the company to exchange or return the product if the product is still under warranty. However, cheap lenses usually won’t have such after-sales service.

If you’re still looking for ways on how to keep a rifle scope from fogging up inside, try these methods:

  • Place the lens inside the oven at a warm temperature.
  • Place the lens under natural sunlight to dry out the moisture.
  • Use a blow dryer to remove water.

For expensive scopes, we do not recommend taking these steps. The best way is to contact the manufacturer directly.

Final Thoughts

We hope that this article of ours has helped you understand how to defog a rifle scope.

Internal and external condensation is an unavoidable problem when using scopes. Be prepared with all necessary equipment and cleaning aids to ensure the complete hunting experience.
