Listener Question. My Gear Is Covered In Soot From The Great Dorset Steam Fair!

To clean a camera and camera lens covered in soot and steam you need to work slowly and gently. Dry the camera out in a warm but natural environment. Remove any dust gently with a small brush. Use a blower/ blower brush to get rid of harder-to-remove bits. Use a magnifying glass to spot unwanted debris. Work slowly. Clean the outside first, remove the lens and see if any soot has got inside and remove that.

Work logically and with care. But, if you have any doubts about doing this pay someone reputable to get your camera cleaned professionally.
