You will also need a strong light, such as a flashlight, that you can direct at a grazing angle against the eyepiece surface. This will reveal grit particles on the lens.

Blow the dust off your eyepiece

Once you are all set, start by blowing off any dust visible on the surface of the eyepieces. You can use the rocket blower for this purpose. It is not recommended to blow with your mouth or use a can of compressed air.

Fire up the rocket blower, aim the nozzle at the eyepiece, and blowhard. Repeat the process from different angles until all the dust is blown off. After that, examine your eyepiece carefully under a strong light to make sure there is no dust or any other foreign matter on the surface.

Clean the surface

Now, it's time to remove the persistent dust particles from the surface of the eyepiece. To do that, lightly moisten a cotton swab with the cleaning solution. Don’t overdo this; You want it damp, but not dripping wet.

With the damp cotton swab, begin at the centre of the lens and wipe outward very gently, in a circular motion, cleaning all the way around the lens. Don't forget to replace the cotton swab frequently as you clean the lens.

Dry the eyepiece

Once your eyepiece is squeaky clean, you can dry it with a clean, soft microfiber cloth. With your index finger in the cloth, wipe the lens in a circular motion, exactly like you did in the previous step.

Lastly, you can use the blower to blow off any lint fibres from the swabs that remain on the lens. Let the eyepiece air dry for at least an hour before you put it back on your telescope or storage case.
