How to Clean Gun Scope Lens

Step#1: Inspect the riflescope lenses

You need to know the extent of dirt on your riflescope lenses before you start cleaning them. Inspecting the lenses makes it easy to understand the dirt and materials you will require to remove the dirt.

At this step, check out the objective and ocular lenses if they allow them to air dry before taking any cleaning procedure. It also applies to cases where the lenses have specs of mud, allow them to air-dry first. Then, once it’s dry, you can use the recommendable canned air to get rid of it.

Step#2: Removal of dust and any other debris on the lenses

The camel’s brush and the micro-fiber cloth can help you remove dust and any other debris off the lenses with ease.

To get rid of the dust, gently move your soft brush from one side of the lens to the other to a point where there is no more dust on the lens. However, there are instances where micro-dirt becomes stubborn. You can use air blasters or an air blower to remove the tinny dirt.

Step#3: Removal of fingerprint and oil stains or any other chronic stain

Fingerprints and smudges of oil on your riflescope lens can lead to blurred vision on your target. Low-quality lens cleaning solutions will not remove these stains from your lenses, and this is why you should consider using the recommendable optic cleaning fluid by the scope manufacturer.

You will need to use lens tissue and with the recommendable cleaning solution. Apply the solution on the lens tissue and not on the lenses directly; gently apply gentle pressure as you clean the lens in a round motion. Start the cleaning of each lens from the middle, progressively going outwards.

If you were not successfully eliminating the dried specs of mud in step#1, use a microfiber to peak up the left dirt. If the specs are still stuck on the lens, dampen your camel hair’s brush with your optic cleaning fluid and gently work on the mud stains until they dissolve and you have removed them from the lens. Avoid pouring the lens cleaning solution onto the lenses directly because the solution can wick around the edges of the mounts of your lenses; this is not good for your scope.

Do not rub the mud stains or any dirt directly on the lens, as this can leave scratch marks on your lenses.

After every use of the camel hairbrush, you either discard it or clean it before storing it. When storing it, it’s advisable to lock it in a zip lock bag.
