The cleaning of particles from library materials (paper, textile, and collagen materials) using a high-speed CO2 snow jet was investigated. The measurements included\ndetermination of the cleaning efficiency, and evaluation of possible adverse effects. The method was compared with nitrogen jet cleaning.

However, application on collagen materials caused\ndegradation of the surface.
