Method for the removal of solid residues deposited on walls, characterised in that the crust 1 of solid residues formed on a surface of the support or structure 2 to be cleaned is broken up by means of the shock wave and/or vibrations produced by the firing of a detonating fuse 3 placed superficially in contact with the said crust of solid residues or of its support 2. <IMAGE>
