Air compressors with filters may stop oil & crud.

Remember that when compressed air is released the rapid expansion of the air causes it to cool. If there is water vapor in the compressed air you may find it deposited as water drops on the surface you are blowing off. Commercial building systems often have a drier so the compressed air has a very low dew point.

Canned air is no better - you are risking your optics with their quality control.


I'd use a bulb type blower to keep all this water stuff to a minimum.
