Step-by-step guide to cleaning the sensor and optics

Preparing Your Workspace and Camera

• Start by choosing a clean, dust-free environment. Avoid areas with airflow or open windows, as airborne particles can settle on your camera sensor during cleaning.
• Gather your cleaning kit: a bulb blower, sensor cleaning swabs, cleaning fluid (like Optical Wonder or a dedicated sensor cleaning solution), lint-free cloths, and a soft brush. Make sure all tools are specifically designed for camera sensor cleaning to prevent scratches or residue.
• Power off your camera and, if possible, remove the battery. For astro cameras like ZWO ASI, disconnect all cables and accessories. Place the camera on a stable, clean surface or a dedicated cleaning board.

Removing Loose Dust and Debris

• Use a bulb blower to gently blow dust off the camera sensor and surrounding area. Hold the camera sensor facing downward so gravity helps remove particles. Don’t use compressed air cans, as they can introduce moisture or propellant residue.
• If stubborn dust remains, a soft, anti-static brush can help. Lightly sweep the sensor surface, but avoid touching the sensor with your fingers or any unapproved tools.

Wet Cleaning for Stubborn Stains

• If you notice dry stains or smudges that the blower and brush can’t remove, it’s time for a wet clean. Apply a few drops of cleaning fluid to a sensor swab (never directly onto the sensor).
• Gently swipe the swab across the sensor in one smooth motion, then use the other side for a second pass. Discard the swab after one use to avoid reintroducing dust or solution residue.
• Inspect the sensor under a bright light. If stains persist, repeat with a fresh swab and cleaning solution. Don’t overdo it—excessive cleaning can risk damage.

Cleaning the Optics and Exterior

• For the camera’s optical window or lens, use a separate lint-free cloth and a small amount of optical cleaning solution. Wipe gently in a circular motion, starting from the center outward.
• Clean the camera body and board with a dry microfiber cloth. Avoid letting cleaning fluid seep into seams or electronic components.

Final Checks Before Use

• After cleaning, reassemble your camera and inspect for any remaining dust or streaks. Take a test image of a bright, uniform surface (like the sky or a white wall) to check for sensor dust or stains.
• If you notice persistent marks, repeat the cleaning process with fresh tools. Don’t rush—patience leads to the best results and protects your camera investment.
