Diagnosis
You're right to be cautious. The front has a camera lens, a microphone port, and the important IR sensor for the rollover detection. Harsh cleaners can haze the lens or damage the sensor's coating.
How to Fix It
Power down and unplug the camera. Use a dry, ultra-soft microfiber cloth (like the kind for glasses or camera lenses) to gently wipe the dome and body. For stubborn fingerprints or smudges, slightly dampen a corner of the microfiber cloth with distilled water—not tap water—and wipe gently, then immediately dry with the dry part of the cloth. Never spray liquid directly onto the unit.
If That Didn't Work
For dust in the small microphone hole or around the base, use a clean, dry, soft-bristled brush (a new makeup brush or camera lens brush works) to gently dislodge it. You can also use a can of compressed air held upright, from a short distance, for a quick burst to blow dust out of crevices.
Heads Up
Absolutely avoid window cleaner, disinfectant wipes, vinegar, or anything abrasive. These can permanently damage the anti-reflective coating on the camera lens, which will ruin your video quality and potentially interfere with the AI's detection accuracy.
