Start with a gentle exterior cleaning: wipe the camera body with a soft cloth lightly dampened with a mild cleaning solution, and gently rub the affected surfaces, especially the rubber grip. The odor is likely from smoke residue/tar on the exterior, so repeated wiping and light scrubbing are usually more effective than strong chemicals. Avoid aggressive solvents.

For lingering odor, place the camera in a closed box for a day or two with an odor absorber nearby, not touching the camera. Community suggestions that helped were:

• a small open container of baking soda, or
• a small bowl of white vinegar in the box.

If using vinegar directly for wiping, dilute it 1:1 with water and use only a damp cloth, not a wet one. Don’t let liquid get into buttons, seams, ports, or the camera interior.

For optical surfaces, clean separately with proper lens/optics cleaning materials and extra care.

In short: gentle wipe-down, repeat as needed, avoid harsh solvents, and use baking soda or vinegar nearby in a sealed box to help remove residual smell.
