Can I use a pressurized computer duster/canned compressed air to clean a DSLR lens or around the camera? Is it safe, or can the strong air pressure cause problems?

I've not seen this recommended for a number of reasons:

  • The high-pressure air can cause dust to move from a bad place to a worse place (as opposed to being removed altogether).
  • The condensation caused by the pressure drop & cooling of the compressed air causes stuff to get frosty. This should be temporary, but isn't likely to help in the short run.
  • You really don't want any of the liquid propellants used to create pressure in the can to stick to anything inside your camera.

Generally, no—it’s not recommended to clean DSLR lenses with canned compressed air.

Main risks:

  • The strong airflow can blow dust deeper into the lens/camera or move it from one problem area to another instead of removing it.
  • Compressed gas can cool rapidly as it sprays, which may cause temporary frosting/condensation.
  • Canned dusters may spit liquid propellant, and you do not want that residue on lens glass or inside the camera.

For lens cleaning, safer options are a manual rocket blower, a soft brush, and proper lens-cleaning tissue or microfiber with lens-cleaning solution when needed. Use the least aggressive method first, and avoid blasting high-pressure air into the camera body or lens openings.
