For instance, in July 2024, improper use of gun cleaner and CLP on optical lenses caused permanent etching and degraded clarity. The solvents damaged protective coatings, leading to irreversible harm.
Amateur astronomer Jack S. demonstrated in March 2025 that using a proper cleaning kit, like the Apertura Optics & Sensor Cleaning Kit, is the safest way to maintain optical gear.
Cleaning Instructions
Proper cleaning keeps your optical gear in top shape. Here’s how to do it:
1. Remove Dust
Use compressed air or an air blower to clear away loose dust. This helps prevent particles from getting into the seals.
2. Brush Away Debris
For stubborn particles, gently use a lens brush – like the Leupold Optics Lens Pen. A soft-bristled toothbrush works well for tight areas.
3. Clean the Lens Surface
To tackle fingerprints or smudges, put a small amount of optical cleaning solution or 90%+ isopropyl alcohol on a microfiber cloth (never directly on the lens). Wipe in a spiral motion, starting from the center and moving outward.
4. Clean the Housing
Tidy up external parts like adjustment turrets and mounting rings with the following methods:
| Area | Cleaning Method |
|---|---|
| Turret Knobs | Compressed air and a soft brush |
| Mounting Rings | Damp microfiber cloth |
| Focus Ring | Dry brush first, then a damp cloth |
| Battery Compartment | Compressed air only |
Make sure all components are clean before moving on.
5. Final Wipe and Dry
Use a dry microfiber cloth for a final wipe. Allow the optic to air dry completely to avoid water spots or coating damage.
