  • the cleaning effect itself is based on the fact that the dry ice particles, which are ultimately CO 2 in solid form, penetrate into the joint filler or the joint filler residues or between the joint filler and the joint edges, sublimate there, which is associated with a considerable increase in volume. and thus detach residues and impurities sticking to the joint flanks.
  • the compressed air transporting the dry ice particles also blows joint filler residues, dust and other impurities out of the joint.
