Is it safe and a good idea to clean DSLR lens using computer dust removal, which has powerful air pressure ?


1 Answer 1


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.
  • \$\begingroup\$ Excellent. I'll go ahead and buy a lens cleaning pen. Can you please suggest one? \$\endgroup\$
