This paper deals with the comparison of two kind of methods for cleaning of air ducts. One is mechanical brushing with different brushes and the second one with compressed air cleaning. In the laboratory and field tests it appeared that the brushing methods were more efficient in metal ducts, whereas the compressed air cleaning was more efficient in plastic ducts. Concerning the oils residues stuck with dust, they were difficult to remove with both the cleaning methods.
